Groupnames Dissapearing from IPA GIDs

Post by sbuchanan0613 » 2018/07/20 15:30:48

Hello,

Hopefully i'm posting this to the correct place.I have setup the Free-IPA LDAP suite (DNS/NTP/LDAP/CA/KRB) on CentOS 7.5.1804.and have been running this with not too many issues for a couple months now. For some reason the following is happening and i'm not too sure what is causing it.

#id -Gn test-user

cannot find name for group ID 10023

Then if I run
# getent group <groupname>
This resolves with a full list of users associated with that group

Lastly when I rerun; #id -Gn test-user
the cannot find name or group ID error message dissipears and the group name resolves to the GID.

This will last a couple of hours and then will be unresolvable again.
Any help would be appreciated

Environment:
Client W/ Issues: CentOS 7.4.1708
SSSD Version: 1.16
NTP is connected to the IPA server and in Sync within 46ms
Kerberos Ticket Exists
IPA-Client Version: 4.5.0

IPA Host: CentOS 7.5.1804
SSSD Version: 1.16
NTP is allowing connections and pulling time from external sources
Kerberos Ticket Exists
IPA-Server Version: 4.5.4

Please let me know if I need to attach any logs.

Thanks in advanced,

Steve

Heres a snippet of the debugged sssd.log:
