Change primary group
by Jannis Mann 19 Mar '20

19 Mar '20

Hi, I've sssd running with ldap provider and therefore use a binding account. In general everything works. I've a question regarding the primary group. When I login with any user who I permitted to in the sssd.conf all users have the Domain Users gorup as primary group. So if I create a file with User a ownership is UserA:Domain\ Users Same goes for UserB etc. Can I have influence on the primary group of the sssd users? Because this seems quite insecure for me. Because I use different permissions for different users (configured via sudoers files). But if every user is in the same group.. Thanks for your input! Jannis

Hey All, Is there an example of how this bug is triggered? https://pagure.io/SSSD/sssd/issue/3571 There's a BZ ntry but I can't access it. I'm not able to replicate this or devise an acceptable scenario using a user/group combination to trigger it. So I'm wondering if there's an example AD user/group case that always triggers this issue. -- Thx,

AD Users not found with error RefErr: DSID-03100781 in log
by Christoph.Kaunzner＠sonydadc.com 11 Mar '20

11 Mar '20

Hi All, I'm using sssd to authenticate users from AD and generally this works fine. However, I have one server that frequently can't resolve AD users: [root@HOST ~]# id aduser(a)domain.com id: aduser(a)domain.com: no such user or: [aduser@HOST ~]# crontab -l crontab: your UID isn't in the passwd file. bailing out. Around that time I see errors like this in the log: [sssd[be[domain.com]]] [sdap_get_generic_op_finished] (0x0400): Search result: Referral(10), 0000202B: RefErr: DSID-03100781, data 0, 1 access points ref 1: 'Domain.com' After a view minutes it works again. What puzzles me is that I have 2 other servers with the same config using that same user which don't have any problem. I'm running sssd- 1.16.4. 21.el7_7.1 on CentOS Linux release 7.7.1908 (Core) This is my sssd.conf: [sssd] debug_level=9 sbus_timeout = 30 reconnection_retries = 3 services = nss, pam config_file_version = 2 domains = domain.com [pam] debug_level=9 pam_verbosity = 3 reconnection_retries = 3 [nss] debug_level=9 reconnection_retries = 3 [domain/domain.com] debug_level=9 ad_site = SITE use_fully_qualified_names = true override_homedir = /home/%u dyndns_update = false ldap_schema = ad id_provider = ad ad_enabled_domains = sub.domain.com, domain.com ad_gpo_access_control = disabled case_sensitive = true cache_credentials = true min_id = 1000 ldap_id_mapping = False ldap_group_nesting_level = 4 ldap_user_primary_group = gidNumber ad_hostname = host.domain.com ignore_group_members = TRUE access_provider = simple simple_allow_groups = group1@domain.com,group2@sub.domain.com,group3@sub.domain.com Thank you, Christoph DISCLAIMER The content of this email and any files transmitted with it may be confidential and intended solely for the use of the individual named.

Re: Can I map an LDAP value of 123456 to a user name of u123456 ?
by patrick.hush＠comcast.net 11 Mar '20

Why on earth would you assign a numeric value to a uid? Just do a ldapmodify and replace the uid with a valid userid (eg. jsmith) and replace uidNumber with the previous value, then get rid of the: ldap_user_uid_number = uid ldap_user_gid_number = uid stuff, you can do this in one ldif with dn: uid=123456,ou=people,dc=example,dc=com changetype: modify replace uid, uidNumber uid: jsmith uidNumber: 123456 - dn: uid=123458,ou=people,dc=example,dc=com changetype: modify replace uid, uidNumber uid: foobar uidNumber: 123458 - (just keep going I'd do an export and work from that) > On March 10, 2020 at 9:30 PM Michael Lake <Mike.Lake(a)uts.edu.au> wrote: > > Example user: > > uid: 123456 > mail: Mike.Lake(a)uts.edu.au mailto:Mike.Lake@uts.edu.au > uidNumber: 200123456 > > ________________________________________ > From: patrick.hush(a)comcast.net mailto:patrick.hush@comcast.net <patrick.hush(a)comcast.net> > Sent: Wednesday, March 11, 2020 9:15 AM > To: End-user discussions about the System Security Services Daemon > Subject: [SSSD-users] Re: Can I map an LDAP value of 123456 to a user name of u123456 ? > > In LDAP what are the uidNumber and uid attributes for a sample user? > On March 10, 2020 at 2:45 PM Michael Lake <Mike.Lake(a)uts.edu.au> wrote: > > Hi > > But I'd still have the problem that my UNIX username needs to be POSIX compliant.

Fully qualified name is a name in the form of user@domain. I.e. if you have [domain/mydomain] in /etc/sssd/sssd.conf the fully qualified name will be number@mydomain. If they are used to login with their email address, you could also switch name attribute to the email address attribute if it is in LDAP.

Can I map an LDAP value of 123456 to a user name of u123456 ?
by Michael Lake 10 Mar '20

10 Mar '20

Hi all I am currently authenticating users with Centos 6 and sssd to an LDAP server. I'll be moving to a Centos 8 so have setup sssd to authenticate to the LDAP server on my test Centos 8 box. However, our users in our LDAP only contains all numeric identifiers for users. Centos 8 no longer accepts all numeric user names and group names Currently my sssd.conf contains: ldap_user_uid_number = uid ldap_user_gid_number = uid override_homedir = /homes/%u Our LDAP server contains "uid" values for users like "123456" I'll still be able to use the LDAP "uid" for UNIX uid and gid but what I would like to be able to do is have the user name (and group name) created by prefixing the LDAP "uid" values with a literal "u" to make them POSIX compliant. Hence a user 123456 with "uid" of 123456 in LDAP can login and end up with a username of "u123456". I can't see a way to do that with a simple template in the "man ssd.conf" Mike Lake UTS CRICOS Provider Code: 00099F DISCLAIMER: This email message and any accompanying attachments may contain confidential information.
