When starting idmapd or stopping it, logs on the LDAP server don't change. But UID and GID's change to nfsnobody when I set Nobody-User and Nobody-Group to nfsnobody in /etc/idmapd.conf .
I don't know that merely restarting the service is going to spark queries against LDAP. You'd probably need to do something to provoke that (like doing an ls).
[General] Verbosity = 9 Domain = nix.my.dom [Mapping] Nobody-User = nfsnobody Nobody-Group = nfsnobody [Translation] [Static] [UMICH_SCHEMA] LDAP_server = idmipa01.nix.my.dom LDAP_base = cn=accounts,DC=NIX,DC=MY,DC=DOM LDAP_people_base = DC=NIX,DC=MY,DC=DOM LDAP_group_base = DC=NIX,DC=MY,DC=DOM
The people basedn should probably be cn=users,cn=accounts,... and the group base cn=groups,cn=accounts,... Unles it cleverly smashes that together with LDAP_base, I'm not sure what it does. The 389-ds access logs will tell you if it is trying at all (note the logs are write-buffered so you won't see immediate updates).
If you have compat enabled then idmapd may be getting multiple entries, one from cn=compat and one from the main tree and that could be confusing it.

Hey Guy's,
Getting below message which in turn fails to list proper UID / GID on NFSv4 mounts from within an unprivileged account. All files show up with owner and group as nobody / nobody when viewed from the client.
Is there a way to structure /etc/idmapd.conf to allow for proper UID / GID resolution? Or perhaps another solution?

Mount looks like this:

You might be able to correlate that to the 389-ds access log to see what queries are being executed.
You probably need to set LDAP_people_base and LDAP_group_base as well.
I think ipa-client-automount only sets the Domain value and doesn't configure the ldap section at all.
