What to Do if Detecting and Applying Changes in Active Directory Fails?

If a non-admin account is used for the Active Directory connector, then the default permissions for this user are not sufficient. Some operations such as a resync process from Active Directory to Directory Server succeeds, but other operations such as detecting and applying changes in Active Directory could fail abruptly. For example, if you synchronize the deletions from Active Directory to Directory Server, then even full control is insufficient. To resolve this, you must use a Domain Administrator account for the Active Directory connector.
