Until I read the referenced message, I'd have said "won't work" - but there might be a way to get it up & running.
What's the actual goal of the replication (above "having a slave")? OpenLDAP is no direct substitute for AD.
It might be helpful to provide info on which SLES you are using and which version of OpenLDAP is installed, for others to jump in.
Thanks for the reply. That's pretty much the goal, having a slave to the Active Directory server. This "slave" is to be used in an all-Linux environment, and the existing AD server exists in an all-Windows environment. Essentially, it is to bridge the gap.
The version of SLES is 11 (Just purchased a few months ago).
