because the other way using internal gal with shared addressbook doesn't work, i want to know if this could work:

Is it possible to edit items in the external datasource?

For example:

  • ExternalGAL is the datasource connected to an external LDAP server
  • ExternalGAL is named the addressbook at galsync@mydomain.com

When i login into galsync@mydomain.com and edit an item in the addressbook ExternalGAL, are these changes synced with the LDAP server?
