Ok, do you know if the LDAP attributes uidNumber and gidNumber are replicated to the Global Catalog in your environment? By default they are not.
You can check this manually as well with ldapsearch on the Global Catalog port 3268:
ldapsearch -H ldap://your-ad-dc.your.ad.domain:3268 -b
'DC=your,DC=ad,DC=domain' samAccountName=groupname
If gidNumber is missing in the Global Catalog object please try if setting
ad_enable_gc = False
in the [domain/...] section of sssd.conf makes the group lookup more reliable.

Hi Sumit,
After adding in the ad_enable_gc=false, it doesn't seem to stop the errors we are getting, the last problem we got (today) was a logged in user had only his uid and the primary GID, not sure if this is a different issue but i'm starting to get the feeling that there is something misconfigured on our SSSD client setup.
Although, since I rolled this out, the machines with the new config did not get the "non-POSIX POSIX group in the cache" problem we've been discussing, so it may be solved, or coincedentally the specific error hasn't come up again.
As an aside, I've noticed that when the backend fetches new data for the cache, sometimes it will just update the ts_cache and sometimes it will update both the cache and the ts_cache. What determines this behaviour? I'm asking because when the cache fetches and updates, it actually fixes the problem when it updates the cache but when it only changes the ts_cache the issue remains, i've added a couple of examples to explain:
Updates both cache and ts_cache [sdap_save_group] (0x0400): Storing info for group group@domain.com [sysdb_set_entry_attr] (0x0200): Entry [name=group@domain.com,cn=groups,cn=domain.com,cn=sysdb] has set [cache, ts_cache] attrs.
Updates only the ts_cache: [sdap_save_group] (0x0400): Storing info for group group@domain.com [sysdb_store_group] (0x1000): The group record of group@domain.com did not change, only updated the timestamp cache
Realistically it should see that the incoming data is different to the cached data no?
Sorry for the heavy message, please let me know if you need any specifics and I'll be glad to provide. Really appreciate the time you're giving to help us out.
Kind Regards, Jamal
