The AcctSync Approach
The Windows PDC has two important components
- Central user database is LDAP only, not a complicated mix of protocols/systems
( relatively speaking ).
- Client computers are unaware of modifications.
The password filter DLL catches windows user password changes and sends those
to a registered script. That script updates the LDAP server. The
OpenLDAP replica running on the windows machine is a regular OpenLDAP replica
and receives all changes done on the master ldap server. It uses the
Perl backend to make updates to the windows operating system.
