Normal users don't have the necessary permissions to do the lookup on LDAP. The authentication process is done usally by root then when you are logged in you can't do lookups. I've documented this here http://www.csse.uwa.edu.au/~ashley/fedora-ds/fedora-ds-26072006.html In Section 3.3 Binding Linux/Unix Machines to LDAPs (way at the bottom) Short story is turn on NSCD, this service binds as root but caches the information for the local user. Usually information you should cache is passwd, group and aliases information which you have to edit /etc/nscd.conf You might want to check this out for NSCD http://www.csse.uwa.edu.au/~ashley/fedora-ds/Fedora%20Miscellaneous%20Problems-23082006.htm Regards Ashley On Wed, 13 Jun 2007, Diwakoe wrote: > Dear all, > > I'm using FC6 with FDS authentication and running well but can not > show groups name only GID when command 'groups' execute on console. > Sometimes we get confuse when we saw some folder not show group name > only gid. > > --- > $groups > id: cannot find name for group ID 10001 > 10001 > --- > > Is there any trick how to show group name not gid on konsole. > > > Thanks, > Diwa > > -- > Fedora-directory-users mailing list > Fedora-directory-users at redhat.com > https://www.redhat.com/mailman/listinfo/fedora-directory-users > > > !DSPAM:272,466f7488187291087211254! > -- Ashley Chew - Systems Administrator School of Computer Science and Software Engineering University of Western Australia Tel: (+61 8) 6488 7082 - Fax: (+61 8) 6488 1089 Ashley[@]csse.uwa.edu.au - http://www.csse.uwa.edu.au/~ashley "There is no such thing as Fate, Fate is what you make of it!"
