You can create a custom
security realm that draws from an existing store of users such as
directory server on the network. To use a custom security realm, you
first create an implementation of the weblogic.security.acl.AbstractListableRealm
interface or the weblogic.security.acl.AbstractManageableRealm
interface and then use the Administration Console to install your
implementation.
The Create a New Basic Realm page appears.
The Settings page for the Custom security realm appears.
