We have had a recurring issue with ZCM which is characterized by an inability to authenticate users in eDir.

To eliminate a link in the chain I have proposed installing eDir on the Windows box that ZCM is running on, so it would have a local replica to talk to. My search-fu didn't find anything on this, so I'm asking here.

Is this a supported configuration? We have a small installation so I'm not overly worried about system load.

Alternatively, we are considering setting up multiple LDAP sources as mentioned in the docs under "10.5 Providing LDAP Load Balancing and Fault Tolerance" but one of the NTS guys told us that LDAP fault tolerance isn't fully functional under Windows. I'm not sure if that's still the case though.
