Hello,
User synchronization from Active Directory is working great, but there’s a minor issue that should be fixed, in my opinion. Once an extension is created and it’s linked to an user, it won’t be updated when a new sync happens. For example, it’s not uncommon for the “displayName” attribute to be changed. Also, sometimes the admin might want to move an extension from an user to another by simply changing the “ipphone” attribute. In this case, FreePBX should change the extension details and also change the linked user manager account.
