Re: LDAP and AD?


To avoid a dual password database, which need synchronization,
I tried another approach. I authenticate the user on the MS Win NT PDC
using PAM SMB or PAM Winbind (included in the latest SAMBA release).
I only use OpenLDAP database for NSS LDAP to  associate UID GID numbers
with real usnames or groups.

We 'll soon migrate our WinNT PDC servers to  Win2K Active Directory.
Then I will try the Active Directory NIS server found int the MS WinSFU
(Service For Unix) package.
If it doesn't work, I will try the solution proposed by Kervin.
Our main goal is to minimize the impact of the dual account
management between MS Win and Linux environments.
