ADS Synchronization and UPDATE Errors, "There is no such object on the server"
There are errors when there are updates on an ADSAccount, as well as when the the AD full sync occurs.
When there is an AD update on an account, the process shows an error saying: "There is no such object on the server":
" Processing task ADSAccount Update failed.
[System.DirectoryServices.DirectoryServicesCOMException] There is no such object on the server."
On the AD full sync process there is another error, "Error accessing LDAP directory."
" Processing task FullSync failed.
 Processing task DoFullsync failed.
 Error loading list of DOMAINDNS from target system.
 Error accessing LDAP directory.( Message: The specified directory service attribute or value does not exist."
The account specified for LDAP login has a blank or incorrect password.
Also, we have seen cases when due to connectivity issues with a domain controller prevent the updates from completing. In this case a reactivation of the process step will allow the update to continue once any connectivity issues have been resolved.
Confirm the account specified for "LDAP login" has the correct password set:
Verify that the domain controller specified in the master data for your domain (Domain controller (sync.)) is accessible and responding to LDAP requests.
