Re: LDAP and AD?

I would not recommend NIS, not if you want anything to do with security.

Why not just continue to use Samba as your PDC? I haven't following Samba development, but I've heard people are already using the Win2k PDC support. Samba+MIT kerb+OpenLDAP

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.

Hi Jacques Landru,

I have a dream to have all passwords and users in LdapServer.


I think you and I had the same dream, how about that? :)

At any rate there are a number of ways to do synchronization already.  I
am working one more way to do this at http://acctsync.sourceforge.net/ .

I am taking the approach that iPlanet did with they NT directory sync
product.  It comprises of a NT/2000 password filter that catches user
password changes and updates the directory, and ldap server plugins that
update NT/2000 when a user is added or a password gets changed.

Although still in Alpha, I have wrote a generic password filter that
calls a external script on user password changes.  My goal is to use
this dll along with a 'passwd.pl' perl script to send this changes to
the OpenLDAP server.  Someone else has wrote a password filter that does
a direct ldap modify on the user's password attribute in the OpenLDAP
server.  The latter is more efficient, but I believe less flexible.
Either way there's a choice.

I have made modifications to the perl backend to have it compile
windows.  The patch is against CVS and is available from


I have tested the patch with activestate perl although, I believe
another perl 5.6 distribution would work with minimal effort.  I don't
know when/if the patch will be incorporated into OpenLDAP CVS.

The final piece of the puzzle is the perl scripts to do the work.  I am
planning to write these sometime this weekend. I'll also include
pre-built binaries if I get the chance as well.  If you are interested
keep an eye on http://acctsync.sourceforge.net/ .
