Hi all, I'm Luigi In my Fedora Server, I installed the Directory Server (I'm using fedora-ds-1.0.2-FC5). In my Windows 2000 Server, instead, I installed Password Sync, that it works fine. In fact, If I modify an user's password, the password is changed in Fedora server too (only if the user is created in Fedora Server too). I can see the Windows' LDAP tree with the ldp client ( or other LDAP client) using 389 and 636 ports. In the Configuration tab (Directory Server), Replication -> userRoot node, I created new Windows Sync Agreement for my Windows 2000 Server, using port 636. I completed the wizard with no errors. But when I right- click into sync and I initiate full re-syncronization, this error appaers: "The consumer initialization has unsuccesfully completed. The error received by the replica is: '81 - LDAP error: Can't contact LDAP server'". I try to connect it to my server using 389 port, and only the Windows Groups are been synchronized (in the Fedora Directory I see only Windows Groups and no user). Must I install the certificates into Fedora Administrator Server too ? (actually I installed the certs only in Fedora Directory Server). In Windows 2000 server, I only installed the CA's certificate that I installed in Fedora-ds. Must I do other setting in Windows 2000 Server or in Fedora Directory Server? help me, please. Thanks all.
