on both samba hosts (donald and pluto) these commands work great:
My pluto:/etc/nsswitch.conf looks like that:
passwd: compat ldap
group: compat ldap
shadow: compat ldap
I want to add, that the described problem works fine if I try it on a share on "donald", my domain controller. The users are displayed fine under the security tab. So where could be the problem?

Hostname "donald" is my domain controller with samba 3.x + OpenLDAP server running. Hostname "pluto" is my other samba 3.x server which was joined to my domain. I use LDAP for my users+groups. I dont have winbind on my machines. On hostname "pluto" I have a share in smb.conf which says:

The SID is S-1-5-21-blablabla-1234567-blabla-500. I manually checked this SID at my LDAP database. Funnily I have two users with this same SID, one is called "root" and the is called "admin". Weird, but not important imho at this point.
Rid -500 is part of the well known SID, it should be for admin user and
shouldn't be used for root (http://support.microsoft.com/kb/243330)

Are you sure that there is a uid/gid mapping for your samba users on
your server. For instance, if you type "id myusername" or "getent
passwd", do you get a uid?
If not, you should check if your /etc/nsswitch.conf configuration is ok.
If you don't use winbind, you should have nssldap configured.
