Directory synchronization is the process of synchronizing the usernames stored in PowerSchool's database with the sign in (user) IDs stored in your LDAP directory. For a user to successfully authenticate in PowerSchool via LDAP, the usernames must match in both PowerSchool and the LDAP Directory.
When LDAP is enabled, usernames are no longer directly editable through the PowerSchool user interface on either the Modify Info for Students or Security Settings for Teachers and Staff pages. Instead, you must use one of the Synchronization processes.
Synchronization can either be performed as a mass operation, using a selection of students or teachers and staff, or one at a time using the LDAP Lookup button on either the Modify Information or Security Settings pages.
