Hey Rob,
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 .

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?
[root@client01 etc]# cat /etc/idmapd.conf|grep -v "#"| sed -e "/^$/d"

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.
