CommuniGate Pro supports Directory-based Domains. Account information in those Domains is stored in the Directory, and the LDAP module can be used to modify Account data in the Directory. Directory-based Domains resemble the architecture of some older Messaging Systems, and CommuniGate Pro supports it for compatibility and migration reasons. See the Directory-Based Domains section for more details.
The LDAP module can also be used to perform basic provisioning operations within regular Domains. This feature is called LDAP Provisioning. If the DN specified in the request "looks like" a DN of a Directory record that some CommuniGate Pro Account has (or could have), the LDAP module does not perform any operation on the Directory at all. Instead of passing the request to the Directory, the LDAP module sends a command directly to the Account Manager, and the Account Manager creates/removes/renames/updates/reads the specified Account. See the Directory Integration section for more details.
