zabbix for monitoring FreeIPA server?
by Tony Brian Albers 24 May '19

Hi guys, Anyone got this working? And if so, how did you do it? I know I can monitor the components separately, but if you know of anything that can do it easier I'd be happy to know about it. /tony -- -- Tony Albers Systems administrator, IT-development Royal Danish Library, Victor Albecks Vej 1, 8000 Aarhus C, Denmark.

ipa-getkeytab: PrincipalName not found
by Harald Dunkel 26 Apr '19

26 Apr '19

Hi folks, maybe I missed something, but shouldn't admin have sufficient privileges to run # ipa-client-install --hostname stretch1.vs.example.de --no-ssh --no-sshd --no-nisdomain --no-sudo --no-ntp --no-dns-sshfp # reboot : : # kinit admin # ipa-getkeytab -s ipa1.example.de -p HTTP/stretch1.vs.example.de -k /etc/apache2/apache2.keytab ? ipa-getkeytab failed with Failed to parse result: PrincipalName not found. I would have expected it to create the principal on the fly. "admin" was created at freeipa install time on the first server, AFAIR. It is member of the "admins" and "trust admins" groups. I am concerned that I corrupted something. Every helpful comment is highly appreciated. Harri

FreeIPA AD Trust with Samba4 ... is it possible?
by D Anderson 01 Apr '19

01 Apr '19

Hello all, I am confused by some of the conflicting documentation about whether this is possible or not. Almost all of the documentation/working examples seem to use an actual Windows Domain Controller. Specifically the part on DNS , as the Samba4 internal DNS server has several know limitations. https://wiki.samba.org/index.php/Samba_Internal_DNS_Back_End#Limitations| >The internal DNS does not support: >zone transfers https://wiki.samba.org/index.php/DNS_Administration#Administering_DNS_on_Wi… >Conditional forwarders are not implemented yet I THINK I got DNS actually working , but had to use solution like here https://www.redhat.com/archives/freeipa-users/2012-October/msg00194.html Although Petr says to stay away from forwarders in IPA Is it better to attempt AD as subdomain of IPA (which I'm currently doing) , or IPA as subdomain of AD ? On both samba4 and freeipa machine I can currently dig SRV records for both domains , but when I attempt ipa add-trust, I see in httpd error logs >[Fri Aug 10 11:58:43.122526 2018] [:error] [pid 6169] ipa: ERROR: Attempt to solve forest trust topology conflicts >[Fri Aug 10 11:58:43.125865 2018] [:error] [pid 6169] ipa: ERROR: non-public: NTSTATUSError: (-1073741601, 'The specified domain did not exist.') Which leads me to believe that no, DNS is not working correctly ( I have all firewall/iptables off and selinux off). I can give more concrete/examples , but before get lost in the weeds wanted to know on broad consensus is it even possible or known bad issues with Samba AD ? Like here https://www.freeipa.org/page/IPAv3_AD_trust#Samba , it says >In order to get properly working MIT krb5-based Samba4 build one have to use --without-ad-dc --with-system-mitkrb5 options when configuring WAF top level build. Which I'm confused ... how to get I get AD trust, if I'm setting up samba without AD abilities?? Yet here https://www.freeipa.org/page/Windows_authentication_against_FreeIPA It recommends a. If you have an AD ( Microsoft ) , use it b. If you don't have a Microsoft AD , setup Samba4 >but it can be configured to trust FreeIPA Does anyone know of a complete A..Z example of how to do that? (what options were used to configure Samba and Freeipa, etc) Thanks

Hi List, I have a master server that had a replica installed. The replica has been uninstalled. When I try to run "ipa-replica-manage del --force replica.server" it fails with: invalid 'PKINIT enabled server': all masters must have IPA master role enabled How can I delete this replica? Thanks, Ralph

nfsidmap/nss_getpwnam fails to resolve users with IPA/NFSv4+krb5
by Robert Sturrock 12 Mar '19

12 Mar '19

Hi All. We have IPA setup in an AD trust to support our Linux fleet. I’m running into a problem trying to get Ubuntu (16.04) clients to resolve names/ids on an NFS-mounted filesystem from an NFS server using NFSv4/krb5. Files and directories show up as ‘nobody’ or an incorrect numerical ID when listed with ‘ls’. RHEL7 clients seem to working fine with a very similar configuration (as far as I can tell). The particulars are: - AD forest has domains ‘localdomain’ and ‘student.localdomain’ (my user identity is ‘user@localdomain’) - IPA domain is ‘ipa.localdomain’ - The NFS server (RHEL7) and clients (Ubu16.04, RHEL7) are both enrolled to IPA (with 'Domain=ipa.localdomain’ in /etc/idmapd.conf). I have mounted the NFS volume on the clients with a simple: mount -t nfs4 nfs-server.ipa.localdomain:/export /mnt Listing my directory as myself (‘rns@localdomain’) on the Ubuntu client, I see: $ ls -ld rns drwx------ 18 nobody 4294967294 4096 Oct 25 15:18 rns .. with these corresponding nfsidmap messages: Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: key: 0x2c254c26 type: uid value: rns@localdomain@ipa.localdomain timeout 600 Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: calling nsswitch->name_to_uid Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nss_getpwnam: name 'rns@localdomain@ipa.localdomain' domain 'ipa.localdomain': resulting localname '(null)' Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nss_getpwnam: name 'rns@localdomain@ipa.localdomain' does not map into domain 'ipa.localdomain' Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: nsswitch->name_to_uid returned -22 Oct 25 16:49:42 ubuntu-16.04-client.sub.localdomain nfsidmap[6163]: nfs4_name_to_uid: final return value is -22 .. whereas on the RHEL7 client, I see: $ ls -ld rns drwx------. 18 rns@localdomain rns@localdomain 4096 Oct 25 15:18 rns Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: key: 0xf113fd2 type: uid value: rns@localdomain@ipa.localdomain timeout 600 Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: nfs4_name_to_uid: calling nsswitch->name_to_uid Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: nss_getpwnam: name 'rns@localdomain@ipa.localdomain' domain 'ipa.localdomain': resulting localname 'rns@localdomain' Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: nfs4_name_to_uid: nsswitch->name_to_uid returned 0 Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30590]: nfs4_name_to_uid: final return value is 0 Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30592]: key: 0x2125a5d2 type: gid value: rns@localdomain@ipa.localdomain timeout 600 Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30592]: nfs4_name_to_gid: calling nsswitch->name_to_gid Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30592]: nfs4_name_to_gid: nsswitch->name_to_gid returned 0 Oct 25 16:56:23 rhel-7-client.sub.localdomain nfsidmap[30592]: nfs4_name_to_gid: final return value is 0 Why does the Ubuntu client's nfsidmap think that my identity doesn’t map into ‘ipa.localdomain’ and therefore (presumably) returns the error code ‘-22’? (My identity resolves ok from the shell, using ‘id rns@localdomain’ and I can login and use local filesystems without issue). The idmapd.conf looks like this: [General] Verbosity = 4 Pipefs-Directory = /run/rpc_pipefs Domain = ipa.localdomain Local-Realms = LOCALDOMAIN, STUDENT.LOCALDOMAIN, IPA.LOCALDOMAIN [Mapping] Nobody-User = nobody Nobody-Group = nogroup [Translation] Method = nsswitch Any pointers appreciated! Regards, Robert.

Web app integration
by Alex Corcoles 11 Mar '19

11 Mar '19

Hi, I've read: https://www.freeipa.org/page/Web_App_Authentication , but there is some stuff that is not clear to me. 1) SAML As I recall, there's Ipsilon and Keycloak. Ipsilon is "dead" and Keycloak is the way to go, right? However, Keycloak setup is not trivial, correct? Running CentOS there is no straightforward way to install and integrate it with a FreeIPA domain, correct? 2) SSO What is the special sauce for users using a browser on an IPA-joined system to log in to apps without even seeing a login form? SPNEGO? I'm using mod_auth_gssapi for some apps, having httpd do the authentication and forward it through REMOTE_USER, but it doesn't do the magic. There are some hints on mod_auth_gssapi's docs, but nothing really clear. 3) How should you deliver apps? Suppose you are a web app developer and you want to deliver a web application which can easily integrate with FreeIPA. What's the most comfortable option you can give? (assuming, for instance, that you want the SSO magic sauce). Is there any difference between apps that will run on the FreeIPA's domain owner's systems or third party apps?

is anyone running Debian as freeipa-client
by Johan Vermeulen 16 Feb '19

16 Feb '19

Hello All, first of all, we have great success running Freeipa and Freeipa-clients on Centos. Thanks for making this possible! I think this is a really important peace of software for Linux. Now it would come in handy if I could field some Debian clients for some purposes. But on the current stable release there is no freeipa client. I have installed some freeipa-clients from unstable, but it's not ideal. I'm wondering, is anyone doing this at the moment. Is there some repo for this? Can this be compiled from source? Thanks for any help. Greetings, J.

external ocsp ?
by veer Schlansky 04 Feb '19

04 Feb '19

My company's PIV/AD credintial is user(a)example.com. We set up our IPA credintial as user(a)linux.example.com example.com and linux.example.com are completedly seperated domain/realms, no trust or interaction whatsoever. I took the user and CA certs on the PIV card and put them into ipa. I was able to authenticate to ipa webui with my PIV card. My question is does ipa do online certificate status protocol check for the user(a)example.com cert? Any way to verify that? Thanks.

de/selecting AD's users
by lejeczek 25 Jan '19

25 Jan '19

hi guys I wonder, and hope you guys could tell if it's possible in IPA, when there is one-way trust established between AD & IPA, to allow only certain account to login & access IPA's resources? An ideal scenario I'm looking for is where all users from AD are initially disallowed to login & access IPA domain, and then admin can allow such user on per user or group basis. Is something like that "built-in" IPA's feature? many thanks, L.

CA master reinstall via replication
by Rob Foehl 21 Jan '19

21 Jan '19

If I have a pair of IPA servers and need to reinstall the one currently holding the CA master, is it actually necessary to promote the other one, or can I just follow the procedure to rebuild the current master via replication and then verify its CA configuration[1] after the fact? Thanks, -Rob [1] Specifically, everything mentioned in https://www.freeipa.org/page/Howto/Promote_CA_to_Renewal_and_CRL_Master
