I am working with a customer running RHEL V6.4. They are using ldap for authentication.
No problem authenticating a users login but the gids are not consistantly being
translated
to group names when running id,ls -l or other commands that display the group
information. They are using sssd with caching enabled.
They are using encrypted communications between the client and server but at my request
they switched to unencrypted (port 389) so we could capture a tcpdump. The dump was
taken
for an ls -l command and it does show two differnt gid's sent to the ldap server and
the
correct group names are being returned.
However, the ls command only shows the gid values and not the names.
They mentioned that if they run getent group groupname, sssd will cache that information
for a while until the entry times out and then the group names are no longer displayed.
so 'id' or 'ls -l' display the names for some time and then only the
numbers are displayed?
Please add the debug_level option to sssd.conf, see man sssd.conf for
details. The higher the level the better. The most interesting log files
here are /var/log/sssd/sssd_nss.log and /var/log/sssd/sssd_DOMAIN.log.
Fell free to send them to me directly if you need some help debugging.

I am not sure how to further debug this and cannot explain why when the ldap server
returns the correct group names, it is not being displayed by the host commands.
Can anyone suggest some other techniques to find out where the group names are being
dropped ?
Any help greatly appreciated.
