Re: problem about smooth migration from files to ldap

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

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.

 Hi all:

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.
