I want to run a Linux/PHP application that will help manage a document repository. To avoid separate user logons/passwords, I located one (DocMGR) that can authenticate via LDAP. The problem is that the LDAP criteria for this app does not meet the setup on our Active Directory. Furthermore, I'm not a domain admin so I can't make changes to the existing configuration (not that I would want to anyway).
Can I set up a separate, Linux-based (openLDAP?) server to replicate the LDAP data and allow users to authenticate against IT instead of the Windows servers? After the initial installation, I would want this to update and replicate with the AD information without any further intervention on my part. Is this possible?
