Hi all, I''m driving crazy. I hope that you can help me. I cannot to establish a sync from Fedora DS to Active Directory (Windows 2000 Server). It seems to me a certificates'' problem. In the Fedora Directory Server, Server Certs Tab, I installed the Fedora''s cert (this cert is signed by my self-signed CA). In the CA Certs Tab, I installed the self-signed CA''s Cert. On the windows Side, in the PassSync, I installed the Fedora Cert. The PassSync works fine and I can syncronize the users'' password when this are changed. On Windows 2000 server, I installed, also, the CA''s cert. Is it exact? Or are there any errors? When I create the Sync, from fedora, 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''". If I try to connect it to my server Win using 389 port, and only the Windows Groups are been synchronized (in the Fedora Directory I see only Windows Groups and no user). Another question: In my Windows Box, shall I install kerberos? Thanks all.
