Proxy Authorization

Proxy authorization is a special form of access control. Proxy authorization or proxy authentication is when an application is forced to use a specific username/password combination to gain access to the server.

With proxy authorization, an administrator can request access to Directory Server by assuming the identity of a regular user. The administrator binds to the directory with his own credentials and is granted the rights of the regular user. This assumed identity is called the proxy user. The DN of that user is called the proxy DN. The proxy user is evaluated as a regular user. Access is denied if the proxy user entry is locked or inactivated or if the password has expired.

An advantage of the proxy mechanism is that you can enable an LDAP application to use a single bind to service multiple users who are accessing Directory Server. Instead of each user having to bind and authenticate, the client application binds to Directory Server and uses proxy rights.
