I sent this previously from the wrong email address so mailman did not send it to the list. Resending and I apologize for if eventually there is a duplicate.
I think it's a bad idea to have an ldap group and a local group with the same name for this exact reason - especially if the gids do not match.
Are you using the NOTFOUND=continue directive?
Your group line in nsswitch.conf might be: group: files [NOTFOUND=continue] ldap

Hi, More info:
the file in filesystem recording uid/gid is based on the uid/gid number, and the gid of local group and gid of OpenLDAP group is different. so the options maybe use `ldap files` in /etc/nsswitch.conf and then use chown to update the gid of the corresponding files and dir.
This is pretty ugly.

I got a non-technical problem here.
I have managed to solved the problem of using OpenLDAP to store user and group infomation and successfully logined into Linux Servers using OpenLDAP.
In the Linux Server, i got LO! CAL groups named like `devel` and `www`, and LOCAL users belong to these groups. Through the /etc/sudoers file, I give different groups with different privileges.
In the OpenLDAP database, i defined my own `devel` and `www` groups. and users in OpenLDAP belongs to their corresponding groups.
The problem is , if i add ldap into /etc/nsswitch.conf, then only the first pair of (users/groups) get the right privileges from /etc/sudoers. That means, if I put `ldap` before `files`, only the users login through OpenLDAP can use the privileges defined in /etc/sudoers. But if I put `files` before `ldap` in /etc/nsswitch.conf, then only Local (users/gr! oups) pair got the privileges from /etc/sudoer2.
I got a bad solution here: give different names to groups from OpenLDAP, and define new privileges in /etc/sudoers for these groups. and after migration, delete the old local groups and old sudo privileges. But this seems to be not that good a solution.
I wonder, what might be the best or right way to migrate from (local user/group) to (ldap user/group) smoothly.
Any clue or advice will be greatly appreciated.
Thank you In advance.
