Windows Sync: Full re-syncronization fails

I have just configured Windows sync (I use RHDS 8.0/RHEL 5.1). When
initiating a full re-syncronization I get these log-entries from the
Linux side:

Internal event: The LDAP server returned an error.

Additional Data
Error value:
00002105: LdapErr: DSID-0C0907C9, comment: Error processing control,
data 0, vece

Anyone familiar with these problems?

Looks like AD received an invalid LDAP message. I've seen this before
when the DirSync control is not formed correctly. But I'm not sure how
this could happen. I suggest running tcpdump or wireshark to capture
the LDAP traffic between Fedora DS and AD to see what LDAP message is
being sent.

Do you know if it is possible to log all ldap-queries sent to AD from DS? I have
enabled all possible logging, but I cannot find the query from the full re-sync
operation in the logs.

Best regards,

Erling

Thanks for the suggestion. I will try tomorrow.
