Upgrading can reset LDAP mapping
If you are upgrading from a system earlier than MyID 10.7 that was connected to another LDAP directory type, the Custom LDAP mappings option will not be available, and configuration settings regarding attribute mapping may be reset to the Active Directory values.
Specifically, if mappings have been removed as the directory does not have an equivalent field, these will be re-added with ADS values. Existing mappings that are modified should remain unchanged, and custom additional field mappings should not be removed.
