GAL Searches in Zimbra Client
The Zimbra client can search the GAL. The GAL search returns a list of directory entries that match the user’s search.
When the user supplies a name to search for, that name is turned into an LDAP search filter similar to the following example:
(|(cn = %s*)(sn=%s*)(gn=%s*)(mail=%s*))
(zimbraMailDeliveryAddress = %s*)
(zimbraMailAlias=%s*)
(zimbraMailAddress = %s*)
The string “%s” is replaced with the name the user is searching for.
