## Overview

Use this page to configure a Realm Adapter Authentication provider.

The Realm Adapter Authentication provider allows you to use users and groups from 6.x security realms in this release of WebLogic Server. Use the Realm Adapter Authentication provider if you store users and groups in the 6.x Windows NT, UNIX, RDBMS security realms or 6.x custom security realm. (There are no equivalents to the 6.x Windows NT, UNIX, RDBMS security realms in this release of WebLogic Server). A Realm Adapter Authentication provider can be configured instead of or in addition to the WebLogic Authentication provider.

When using Compatibility Security, a Realm Adapter Authentication provider is by default configured for the CompatibilityRealm. However, you can configure a Realm Adapter Authentication provider in any security realm.

The Realm Adapter Authentication provider also allows use of implementations of the `weblogic.security.acl.CertAuthenticator` class with this release of WebLogic Server. The Realm Adapter Authentication provider includes an Identity Assertion provider which provides identity assertion based on X.509 tokens.
