6:48 a.m.
I have an inherited IPA domain that is a subdomain of an active directory domain, e.g.
ipa.ad1.com as a child of ad1.com. The IPA domain has AD Trust enabled and a one way
domain trust to another AD sub domain, e.g. we want to use user logins from the AD domain
users.ad2.com which is a child domain of ad2.com. We are also using AD security group
from the user.ad2.com domain to apply group based access control. e.g. we are using
simple authentication on SSSD to limit who can login and using AD groups to define sudo
access. This users domain and AD servers is managed by another team.
Everything was working for some time and then we started seeing intermittent problems with
authentication, a quick restart of the IPA server would resolve the problem temporarily,
but then it would stop again. Even if we could login using SSH keys the sudo access would
not work, it would appear to lose group membership details.
I have recently updated all of the IPA nodes to RHEL9 and made sure that DNS is updated
correctly.
The sssd.conf configuration on the IPA server looks as follows
[domain/ipa.ad1.com]
debug_level = 6
id_provider = ipa
ipa_server = ipa-3.ipa.ad1.com
ipa_domain = ipa.ad1.com
ipa_hostname = ipa-3.ipa.ad1.com
auth_provider = ipa
chpass_provider = ipa
access_provider = ipa
cache_credentials = True
ldap_tls_cacert = /etc/ipa/ca.crt
krb5_store_password_if_offline = True
sudo_provider = ipa
autofs_provider = ipa
subdomains_provider = ipa
session_provider = ipa
hostid_provider = ipa
ipa_server_mode = True
subdomain_homedir = /home/%u
default_shell = /bin/bash
override_shell = /bin/bash
[sssd]
services = nss, pam, sudo, ifp
domains = ipa.ad1.com
domain_resolution_order = users.ad2.com
[nss]
homedir_substring = /home
[pam]
[sudo]
[autofs]
[ssh]
[pac]
[ifp]
allowed_uids = ipaapi, root
[session_recording]
I have debug level 6 enabled on SSSD and when I check the domain status I see the
following more often than not. The ad2.com forest domains are offline. They go online
and then as soon as someone tries to login again then either both or just the
users.ad2.com domain go offline which causes the login to fail.
ipa.ad1.com Online status: Online
ad1.com Online status: Online
ad2.com Online status: Offline
users.ad2.com Online status: Offline
When I look at the SSSD domain logs I see the following (I have replaced internal domain
names or hostname)

As far as I can tell the users.ad2.com domain is "Active", but the bind fails to
the domain which forces a domain check to take place. Ultimately, this fails and the
domain is flagged offline so the authentication fails.
There seems to be some odd lines where the users.ad2.com validation is trying to connect
to servers from the ad1.com domain and global catalog validation which is failing. Not
sure why this would be taking place.
This seems to culminate in the line
(2023-06-07 16:25:55): [be[auth.ssdis.loc]] [fo_resolve_service_send] (0x0020): [RID#1162]
No available servers for service 'sd_gc_AD2.COM'
I can see actions taking place but cannot determine why they are taking place. I can
kinit as a users.ad2.com user successfully. Likewise I can getent users and groups
successfully and see the details correctly. Yet authentication and authorisation is
failing for SSH logins
Any help or guidance on resolving this problem would be appreciated.

I have an inherited IPA domain that is a subdomain of an active
directory domain, e.g. ipa.ad1.com as a child of ad1.com. The IPA domain has AD Trust
enabled and a one way domain trust to another AD sub domain, e.g. we want to use user
logins from the AD domain users.ad2.com which is a child domain of ad2.com. We are also
using AD security group from the user.ad2.com domain to apply group based access control.
e.g. we are using simple authentication on SSSD to limit who can login and using AD groups
to define sudo access. This users domain and AD servers is managed by another team.
Everything was working for some time and then we started seeing intermittent problems
with authentication, a quick restart of the IPA server would resolve the problem
temporarily, but then it would stop again. Even if we could login using SSH keys the sudo
access would not work, it would appear to lose group membership details.
I have recently updated all of the IPA nodes to RHEL9 and made sure that DNS is updated
correctly.
Hi,
this might be related to https://github.com/SSSD/sssd/issues/6600 but it
looks like not exactly the same issue.
Can you share /etc/krb5.conf and all files from /etc/krb5.conf.d/ and
/var/lib/sss/pubconf/krb5.include.d/
bye,
Sumit
The sssd.conf configuration on the IPA server looks as follows

I have debug level 6 enabled on SSSD and when I check the domain status I see the
following more often than not. The ad2.com forest domains are offline. They go online
and then as soon as someone tries to login again then either both or just the
users.ad2.com domain go offline which causes the login to fail.
ipa.ad1.com Online status: Online
ad1.com Online status: Online
ad2.com Online status: Offline
users.ad2.com Online status: Offline
When I look at the SSSD domain logs I see the following (I have replaced internal domain

********************** BACKTRACE DUMP ENDS HERE *********************************
As far as I can tell the users.ad2.com domain is "Active", but the bind fails
to the domain which forces a domain check to take place. Ultimately, this fails and the
domain is flagged offline so the authentication fails.
There seems to be some odd lines where the users.ad2.com validation is trying to connect
to servers from the ad1.com domain and global catalog validation which is failing. Not
sure why this would be taking place.
This seems to culminate in the line
(2023-06-07 16:25:55): [be[auth.ssdis.loc]] [fo_resolve_service_send] (0x0020):
[RID#1162] No available servers for service 'sd_gc_AD2.COM'
I can see actions taking place but cannot determine why they are taking place. I can
kinit as a users.ad2.com user successfully. Likewise I can getent users and groups
successfully and see the details correctly. Yet authentication and authorisation is
failing for SSH logins
Any help or guidance on resolving this problem would be appreciated.

I am still looking into my problem, a reboot of an IPA server seems to allow
authentication and AD group authorisation to work for a period of time and then it stops.
Authentication will continue to work if the user is cached in the SSSD cache, but trying
to use sudo fails as it can no longer get the membership details.

Hi,
assuming that auth.ssdis.loc is the domain with issues can you try if
adding
.auth.ssdis.loc = AUTH.SSDIS.LOC
auth.ssdis.loc = AUTH.SSDIS.LOC
to the [domain_realm] of /etc/krb5.conf makes is more reliable?
bye,
Sumit
