Hey Guy's,
Getting below message which in turn fails to list proper UID / GID on NFSv4 mounts from within an unprivileged account. All files show up with owner and group as nobody / nobody when viewed from the client.
Is there a way to structure /etc/idmapd.conf to allow for proper UID / GID resolution? Or perhaps another solution?

The people basedn should probably be cn=users,cn=accounts,... and the group base cn=groups,cn=accounts,... Unles it cleverly smashes that together with LDAP_base, I'm not sure what it does. The 389-ds access logs will tell you if it is trying at all (note the logs are write-buffered so you won't see immediate updates).
If you have compat enabled then idmapd may be getting multiple entries, one from cn=compat and one from the main tree and that could be confusing it.

Nothing. Once at restart of the host do I see something from ls but on second execution of ls or any type of directory interaction, nothing happens. Then it repeats randomly.
[General] Verbosity = 9 Domain = nix.my.dom [Mapping] Nobody-User = nfsnobody Nobody-Group = nfsnobody [Translation] [Static] [UMICH_SCHEMA] LDAP_server = idmipa01.nix.my.dom LDAP_base = cn=accounts,DC=NIX,DC=MY,DC=DOM LDAP_people_base = DC=NIX,DC=MY,DC=DOM LDAP_group_base = DC=NIX,DC=MY,DC=DOM
The people basedn should probably be cn=users,cn=accounts,... and the group base cn=groups,cn=accounts,... Unles it cleverly smashes that together with LDAP_base, I'm not sure what it does. The 389-ds access logs will tell you if it is trying at all (note the logs are write-buffered so you won't see immediate updates).
If you have compat enabled then idmapd may be getting multiple entries, one from cn=compat and one from the main tree and that could be confusing it.
No difference. Even the IP defined users are having this issue.
However, and this may be a very dumb question, but you raised 389-ds logs. I'm using IPA Server, not 389-ds unless you're implying I may need packages? The IPA servers come with 389-ds-base installed but do I need this or something else on the IPA clients as well?
In the existing IPA logs, no other log entries corrolate with the nfsidmapd messages on the client.

and I'm not sure what variables idmapd.conf uses for password and user. Still, I've left the LAB KDC open so no users and passes are needed for simple lookups.

might be to blame. It's the first line that shows localdomain, but it should not. My hosts file:

You might be able to correlate that to the 389-ds access log to see what queries are being executed.
You probably need to set LDAP_people_base and LDAP_group_base as well.
I think ipa-client-automount only sets the Domain value and doesn't configure the ldap section at all.

Nothing. Once at restart of the host do I see something from ls but on second execution of ls or any type of directory interaction, nothing happens. Then it repeats randomly.
Can you expand on this? What are you seeing on the client side? What queries do you see in LDAP related to the request (any?) Remember that the 389-ds access log is buffered so it can take up to 30 seconds for the logs to update.

You might be able to correlate that to the 389-ds access log to see what queries are being executed.
You probably need to set LDAP_people_base and LDAP_group_base as well.
I think ipa-client-automount only sets the Domain value and doesn't configure the ldap section at all.

When starting idmapd or stopping it, logs on the LDAP server don't change. But UID and GID's change to nfsnobody when I set Nobody-User and Nobody-Group to nfsnobody in /etc/idmapd.conf .
I don't know that merely restarting the service is going to spark queries against LDAP. You'd probably need to do something to provoke that (like doing an ls).
Nothing. Once at restart of the host do I see something from ls but on second execution of ls or any type of directory interaction, nothing happens. Then it repeats randomly.
Can you expand on this? What are you seeing on the client side? What queries do you see in LDAP related to the request (any?) Remember that the 389-ds access log is buffered so it can take up to 30 seconds for the logs to update.

Got it. Here is the 389-ds log at the same time as the client prints these nfsidmap messages:

[General] Verbosity = 9 Domain = nix.my.dom [Mapping] Nobody-User = nfsnobody Nobody-Group = nfsnobody [Translation] [Static] [UMICH_SCHEMA] LDAP_server = idmipa01.nix.my.dom LDAP_base = cn=accounts,DC=NIX,DC=MY,DC=DOM LDAP_people_base = DC=NIX,DC=MY,DC=DOM LDAP_group_base = DC=NIX,DC=MY,DC=DOM
The people basedn should probably be cn=users,cn=accounts,... and the group base cn=groups,cn=accounts,... Unles it cleverly smashes that together with LDAP_base, I'm not sure what it does. The 389-ds access logs will tell you if it is trying at all (note the logs are write-buffered so you won't see immediate updates).
If you have compat enabled then idmapd may be getting multiple entries, one from cn=compat and one from the main tree and that could be confusing it.
No difference. Even the IP defined users are having this issue.
However, and this may be a very dumb question, but you raised 389-ds logs. I'm using IPA Server, not 389-ds unless you're implying I may need packages? The IPA servers come with 389-ds-base installed but do I need this or something else on the IPA clients as well?
In the existing IPA logs, no other log entries corrolate with the nfsidmapd messages on the client.
Method = umich_ldap,nsswitch,static GSS-Methods = umich_ldap,nsswitch,static
However it still lists:
Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: user_dn : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: passwd : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: use_ssl : no Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: ca_cert : <not-supplied>
and I'm not sure what variables idmapd.conf uses for password and user. Still, I've left the LAB KDC open so no users and passes are needed for simple lookups.
After setting the above, the messages in the logs changed slightly:

(Port 389 between client and server are open.) Seems like the line:
Mar 15 01:29:24 ipaclient01 nfsidmap[1853]: key: 0x62dd191 type: uid value: tomk@localdomain timeout 600
might be to blame. It's the first line that shows localdomain, but it should not. My hosts file:
[root@ipaclient01 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.236 ipaclient01.nix.my.dom ipaclient01 [root@ipaclient01 ~]#
Guessing key get's it's info from /etc/hosts directly and I should look at that?

Hey Guy's,
Getting below message which in turn fails to list proper UID / GID on NFSv4 mounts from within an unprivileged account. All files show up with owner and group as nobody / nobody when viewed from the client.
Is there a way to structure /etc/idmapd.conf to allow for proper UID / GID resolution? Or perhaps another solution?

You might be able to correlate that to the 389-ds access log to see what queries are being executed.
You probably need to set LDAP_people_base and LDAP_group_base as well.
I think ipa-client-automount only sets the Domain value and doesn't configure the ldap section at all.

When starting idmapd or stopping it, logs on the LDAP server don't change. But UID and GID's change to nfsnobody when I set Nobody-User and Nobody-Group to nfsnobody in /etc/idmapd.conf .
I don't know that merely restarting the service is going to spark queries against LDAP. You'd probably need to do something to provoke that (like doing an ls).
Nothing. Once at restart of the host do I see something from ls but on second execution of ls or any type of directory interaction, nothing happens. Then it repeats randomly.
Can you expand on this? What are you seeing on the client side? What queries do you see in LDAP related to the request (any?) Remember that the 389-ds access log is buffered so it can take up to 30 seconds for the logs to update.

Got it. Here is the 389-ds log at the same time as the client prints these nfsidmap messages:

Ok I have zero experience with nfsidmap over LDAP but a few observations:
- Your search base is wrong. For users it should cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM - It is searching on a non-existent objectclass From what I can tell you need to set NFSv4_person_objectclass=posixaccount NFSv4_name_attr=uid
An alternate thing to try is to set Method=sss instead of umich_ldap and see if that helps.

Cheers, Tom
[General] Verbosity = 9 Domain = nix.my.dom [Mapping] Nobody-User = nfsnobody Nobody-Group = nfsnobody [Translation] [Static] [UMICH_SCHEMA] LDAP_server = idmipa01.nix.my.dom LDAP_base = cn=accounts,DC=NIX,DC=MY,DC=DOM LDAP_people_base = DC=NIX,DC=MY,DC=DOM LDAP_group_base = DC=NIX,DC=MY,DC=DOM
The people basedn should probably be cn=users,cn=accounts,... and the group base cn=groups,cn=accounts,... Unles it cleverly smashes that together with LDAP_base, I'm not sure what it does. The 389-ds access logs will tell you if it is trying at all (note the logs are write-buffered so you won't see immediate updates).
If you have compat enabled then idmapd may be getting multiple entries, one from cn=compat and one from the main tree and that could be confusing it.
No difference. Even the IP defined users are having this issue.
However, and this may be a very dumb question, but you raised 389-ds logs. I'm using IPA Server, not 389-ds unless you're implying I may need packages? The IPA servers come with 389-ds-base installed but do I need this or something else on the IPA clients as well?
In the existing IPA logs, no other log entries corrolate with the nfsidmapd messages on the client.
Method = umich_ldap,nsswitch,static GSS-Methods = umich_ldap,nsswitch,static
However it still lists:
Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: user_dn : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: passwd : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: use_ssl : no Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: ca_cert : <not-supplied>
and I'm not sure what variables idmapd.conf uses for password and user. Still, I've left the LAB KDC open so no users and passes are needed for simple lookups.
After setting the above, the messages in the logs changed slightly:

(Port 389 between client and server are open.) Seems like the line:
Mar 15 01:29:24 ipaclient01 nfsidmap[1853]: key: 0x62dd191 type: uid value: tomk@localdomain timeout 600
might be to blame. It's the first line that shows localdomain, but it should not. My hosts file:
[root@ipaclient01 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.236 ipaclient01.nix.my.dom ipaclient01 [root@ipaclient01 ~]#
Guessing key get's it's info from /etc/hosts directly and I should look at that?

You might be able to correlate that to the 389-ds access log to see what queries are being executed.
You probably need to set LDAP_people_base and LDAP_group_base as well.
I think ipa-client-automount only sets the Domain value and doesn't configure the ldap section at all.

When starting idmapd or stopping it, logs on the LDAP server don't change. But UID and GID's change to nfsnobody when I set Nobody-User and Nobody-Group to nfsnobody in /etc/idmapd.conf .
I don't know that merely restarting the service is going to spark queries against LDAP. You'd probably need to do something to provoke that (like doing an ls).
Nothing. Once at restart of the host do I see something from ls but on second execution of ls or any type of directory interaction, nothing happens. Then it repeats randomly.
Can you expand on this? What are you seeing on the client side? What queries do you see in LDAP related to the request (any?) Remember that the 389-ds access log is buffered so it can take up to 30 seconds for the logs to update.

Got it. Here is the 389-ds log at the same time as the client prints these nfsidmap messages:

Ok I have zero experience with nfsidmap over LDAP but a few observations:
- Your search base is wrong. For users it should
cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM
- It is searching on a non-existent objectclass From what I can tell you
need to set NFSv4_person_objectclass=posixaccount NFSv4_name_attr=uid
An alternate thing to try is to set Method=sss instead of umich_ldap and see if that helps.
rob
Thanks Rob. But unfortunately none of those did the trick.
[General] Verbosity = 9 Local-Realms = NIX.MY.DOM,MY.DOM Domain = nix.my.dom [Mapping] [Translation] Method = sss,umich_ldap,nsswitch,static GSS-Methods = sss,umich_ldap,nsswitch,static [Static] [UMICH_SCHEMA] LDAP_server = idmipa01.nix.my.dom LDAP_base = cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM LDAP_people_base = DC=NIX,DC=MY,DC=DOM LDAP_group_base = DC=NIX,DC=MY,DC=DOM NFSv4_person_objectclass = posixaccount NFSv4_name_attr = uid
Well the weekend's here though so maybe I can spend a little more time focusing on this and finally get it solved. The tip to use sss as the Method was great and I aslo added it to the GSS-Methods as well but no luck. The fact that localdomain even appears in the logs bothers me. I don't think it should given the Domain is set correctly in the /etc/idmapd.conf file.

[General] Verbosity = 9 Domain = nix.my.dom [Mapping] Nobody-User = nfsnobody Nobody-Group = nfsnobody [Translation] [Static] [UMICH_SCHEMA] LDAP_server = idmipa01.nix.my.dom LDAP_base = cn=accounts,DC=NIX,DC=MY,DC=DOM LDAP_people_base = DC=NIX,DC=MY,DC=DOM LDAP_group_base = DC=NIX,DC=MY,DC=DOM
The people basedn should probably be cn=users,cn=accounts,... and the group base cn=groups,cn=accounts,... Unles it cleverly smashes that together with LDAP_base, I'm not sure what it does. The 389-ds access logs will tell you if it is trying at all (note the logs are write-buffered so you won't see immediate updates).
If you have compat enabled then idmapd may be getting multiple entries, one from cn=compat and one from the main tree and that could be confusing it.
No difference. Even the IP defined users are having this issue.
However, and this may be a very dumb question, but you raised 389-ds logs. I'm using IPA Server, not 389-ds unless you're implying I may need packages? The IPA servers come with 389-ds-base installed but do I need this or something else on the IPA clients as well?
In the existing IPA logs, no other log entries corrolate with the nfsidmapd messages on the client.
Method = umich_ldap,nsswitch,static GSS-Methods = umich_ldap,nsswitch,static
However it still lists:
Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: user_dn : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: passwd : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: use_ssl : no Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: ca_cert : <not-supplied>
and I'm not sure what variables idmapd.conf uses for password and user. Still, I've left the LAB KDC open so no users and passes are needed for simple lookups.
After setting the above, the messages in the logs changed slightly:
Mar 15 01:29:24 ipaclient01 systemd-logind: New session 5 of user tomk. Mar 15 01:29:24 ipaclient01 systemd: Started Session 5 of user tomk.

(Port 389 between client and server are open.) Seems like the line:
Mar 15 01:29:24 ipaclient01 nfsidmap[1853]: key: 0x62dd191 type: uid value: tomk@localdomain timeout 600
might be to blame. It's the first line that shows localdomain, but it should not. My hosts file:
[root@ipaclient01 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.236 ipaclient01.nix.my.dom ipaclient01 [root@ipaclient01 ~]#
Guessing key get's it's info from /etc/hosts directly and I should look at that?

I don't know that merely restarting the service is going to spark queries against LDAP. You'd probably need to do something to provoke that (like doing an ls).
Nothing. Once at restart of the host do I see something from ls but on second execution of ls or any type of directory interaction, nothing happens. Then it repeats randomly.
Can you expand on this? What are you seeing on the client side? What queries do you see in LDAP related to the request (any?) Remember that the 389-ds access log is buffered so it can take up to 30 seconds for the logs to update.

Got it. Here is the 389-ds log at the same time as the client prints these nfsidmap messages:

Ok I have zero experience with nfsidmap over LDAP but a few observations:
- Your search base is wrong. For users it should
cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM
- It is searching on a non-existent objectclass From what I can tell you
need to set NFSv4_person_objectclass=posixaccount NFSv4_name_attr=uid
An alternate thing to try is to set Method=sss instead of umich_ldap and see if that helps.
rob
Thanks Rob. But unfortunately none of those did the trick.
[General] Verbosity = 9 Local-Realms = NIX.MY.DOM,MY.DOM Domain = nix.my.dom [Mapping] [Translation] Method = sss,umich_ldap,nsswitch,static GSS-Methods = sss,umich_ldap,nsswitch,static [Static] [UMICH_SCHEMA] LDAP_server = idmipa01.nix.my.dom LDAP_base = cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM LDAP_people_base = DC=NIX,DC=MY,DC=DOM LDAP_group_base = DC=NIX,DC=MY,DC=DOM NFSv4_person_objectclass = posixaccount NFSv4_name_attr = uid
Well the weekend's here though so maybe I can spend a little more time focusing on this and finally get it solved. The tip to use sss as the Method was great and I aslo added it to the GSS-Methods as well but no luck. The fact that localdomain even appears in the logs bothers me. I don't think it should given the Domain is set correctly in the /etc/idmapd.conf file.
I'm using NFS Ganesha for my NFS mounts ( It's a user space version of NFS. ) However, they don't need the idmapd service running and load only the idmapd libraries.
But the default value for the Domain in the idmapd libraries is localdomain and perhaps that's why it keeps showing up even though I explicitly set the Domain = nix.my.dom .

And perhaps that's why things don't work. Guess I'll see how all this works with the built in Kernel NFS module.

The people basedn should probably be cn=users,cn=accounts,... and the group base cn=groups,cn=accounts,... Unles it cleverly smashes that together with LDAP_base, I'm not sure what it does. The 389-ds access logs will tell you if it is trying at all (note the logs are write-buffered so you won't see immediate updates).
If you have compat enabled then idmapd may be getting multiple entries, one from cn=compat and one from the main tree and that could be confusing it.
No difference. Even the IP defined users are having this issue.
However, and this may be a very dumb question, but you raised 389-ds logs. I'm using IPA Server, not 389-ds unless you're implying I may need packages? The IPA servers come with 389-ds-base installed but do I need this or something else on the IPA clients as well?
In the existing IPA logs, no other log entries corrolate with the nfsidmapd messages on the client.
Method = umich_ldap,nsswitch,static GSS-Methods = umich_ldap,nsswitch,static
However it still lists:
Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: user_dn : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: passwd : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: use_ssl : no Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: ca_cert : <not-supplied>
and I'm not sure what variables idmapd.conf uses for password and user. Still, I've left the LAB KDC open so no users and passes are needed for simple lookups.
After setting the above, the messages in the logs changed slightly:

(Port 389 between client and server are open.) Seems like the line:
Mar 15 01:29:24 ipaclient01 nfsidmap[1853]: key: 0x62dd191 type: uid value: tomk@localdomain timeout 600
might be to blame. It's the first line that shows localdomain, but it should not. My hosts file:
[root@ipaclient01 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.236 ipaclient01.nix.my.dom ipaclient01 [root@ipaclient01 ~]#
Guessing key get's it's info from /etc/hosts directly and I should look at that?

Can you expand on this? What are you seeing on the client side? What queries do you see in LDAP related to the request (any?) Remember that the 389-ds access log is buffered so it can take up to 30 seconds for the logs to update.

Got it. Here is the 389-ds log at the same time as the client prints these nfsidmap messages:

Ok I have zero experience with nfsidmap over LDAP but a few observations:
- Your search base is wrong. For users it should
cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM
- It is searching on a non-existent objectclass From what I can tell you
need to set NFSv4_person_objectclass=posixaccount NFSv4_name_attr=uid
An alternate thing to try is to set Method=sss instead of umich_ldap and see if that helps.

Thanks Rob. But unfortunately none of those did the trick.
[General] Verbosity = 9 Local-Realms = NIX.MY.DOM,MY.DOM Domain = nix.my.dom [Mapping] [Translation] Method = sss,umich_ldap,nsswitch,static GSS-Methods = sss,umich_ldap,nsswitch,static [Static] [UMICH_SCHEMA] LDAP_server = idmipa01.nix.my.dom LDAP_base = cn=users,cn=accounts,DC=NIX,DC=MY,DC=DOM LDAP_people_base = DC=NIX,DC=MY,DC=DOM LDAP_group_base = DC=NIX,DC=MY,DC=DOM NFSv4_person_objectclass = posixaccount NFSv4_name_attr = uid
Well the weekend's here though so maybe I can spend a little more time focusing on this and finally get it solved. The tip to use sss as the Method was great and I aslo added it to the GSS-Methods as well but no luck. The fact that localdomain even appears in the logs bothers me. I don't think it should given the Domain is set correctly in the /etc/idmapd.conf file.
I'm using NFS Ganesha for my NFS mounts ( It's a user space version of NFS. ) However, they don't need the idmapd service running and load only the idmapd libraries.
But the default value for the Domain in the idmapd libraries is localdomain and perhaps that's why it keeps showing up even though I explicitly set the Domain = nix.my.dom .

And perhaps that's why things don't work. Guess I'll see how all this works with the built in Kernel NFS module.

No difference. Even the IP defined users are having this issue.
However, and this may be a very dumb question, but you raised 389-ds logs. I'm using IPA Server, not 389-ds unless you're implying I may need packages? The IPA servers come with 389-ds-base installed but do I need this or something else on the IPA clients as well?
In the existing IPA logs, no other log entries corrolate with the nfsidmapd messages on the client.
Method = umich_ldap,nsswitch,static GSS-Methods = umich_ldap,nsswitch,static
However it still lists:
Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: user_dn : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: passwd : <not-supplied> Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: use_ssl : no Mar 15 01:15:56 ipaclient01 rpc.idmapd: rpc.idmapd: umichldap_init: ca_cert : <not-supplied>
and I'm not sure what variables idmapd.conf uses for password and user. Still, I've left the LAB KDC open so no users and passes are needed for simple lookups.
After setting the above, the messages in the logs changed slightly:

(Port 389 between client and server are open.) Seems like the line:
Mar 15 01:29:24 ipaclient01 nfsidmap[1853]: key: 0x62dd191 type: uid value: tomk@localdomain timeout 600
might be to blame. It's the first line that shows localdomain, but it should not. My hosts file:
[root@ipaclient01 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.0.236 ipaclient01.nix.my.dom ipaclient01 [root@ipaclient01 ~]#
Guessing key get's it's info from /etc/hosts directly and I should look at that?

Solved.
Here's the solution in case it can help someone else.
To get a certain feature in NFS Ganesha, I had to compile the V2.6 release from source. When configuring to compile, idmapd support got disabled since packages were missing:
libnfsidmap-devel-0.25-17.el7.x86_64
Installed the above package and recompiled with nfsidmap support enabled and this issue went away. Users now show up properly off the NFS mount on clients.
