2 Server Environment:
SharePoint 2013 On Server 2008 R2
SQL 2008 R2
AD is 2 domain servers - primary and secondary - Server 2003 w/ 2003 AD Functional Level
SharePoint User Profile service is configured and I can get the Synchronization service started so I am not "stuck on starting". Also, I have verified with AD tools that I can connect to the AD servers and that All replicate dir permissions are set correctly according to Spence Harbar's setup "Bible" :-)
When I try to run a Full Sync via the SharePoint user profile import (the SP2010 way) I get the following error on the DS_FULLIMPORT step in FIM
The replication operation encountered a database error / error code 8451
When I run the AD Import I get the following Error in the SharePoint ULS logs:
ScanDirSyncChanges: Exception thrown by Dirsync request: page 0, LdapServer 'xxx.xxx.dom, rootDn 'DC=XXX,DC=dom', exception 'System.DirectoryServices.Protocols.DirectoryOperationException: The server cannot handle directory requests.
I can find almost nothing on this anywhere. There was a .Net 2.0 hotfix for the 2nd error but that has been applied in a service pack already.
Help. I have built and rebuilt the User Profile Service multiple time with the same results. I'm at a loss.
