Use this page to establish trust between WebLogic domains. A trust relationship is established when principals in a Subject from one WebLogic domain are accepted as principals in the local domain.
The domain credential is generated when WebLogic Server is started. This process ensures that by default no two WebLogic Server domains have the same credential. To enable trust between two WebLogic Server domains, you must explicitly specifiy the same value for the credential in both WebLogic Server domains.
