Migration from WebLogic Server 6.x

Because the security framework in WebLogic Server since version 7.0 and later has been completely overhauled from previous versions, existing security solutions must be updated to work with versions 7.0 and 8.1. This includes existing security realms and any custom security code. This section provides a brief overview of this topic. More information can be found at http://e-docs.bea.com/wls/docs81/upgrade/upgrade6xto81.html#security.

Compatibility Realm

In providing an overhauled security framework, BEA has tried not to alienate existing users by providing a security compatibility mode. If you boot WebLogic Server 8.1 using a WebLogic Server 6.x config.xml file, two security realms will be created: the myrealm realm as described earlier and the compatibility realm. The compatibility realm, along with Realm adapter authentication providers, will allow access to existing users, groups, and access control lists (ACLs). This realm is deprecated and should be used as an interim method while you reconfigure your application to work with 8.1 security.

Realm Adapter Authentication Provider

The realm adapter authentication provider is a special type of authentication provider that enables you to continue to use users and groups stored in a Windows NT, Unix, RDBMS, or custom WebLogic Server 6.x security realm. It provides limited capability to 6.x security realms. Refer to WebLogic Server documentation to make sure that your applications will work with the limited feature set offered by such backward compatibility.
