In Compatibility security, the LDAP V2 realm is configured as a custom security realm.
The LDAP tree and schema is different for every LDAP server. WebLogic Server includes templates for the supported LDAP servers. These templates specify default configuration information used to represent users and groups in each of the supported LDAP servers.
The Create a New Basic Realm page appears.
When configuring the Caching realm, select the LDAP Realm V2 option from the pull-down menu for the Basic Realm attribute on the Caching Realms: Configuration: General page. The Basic Realm attribute defines the association between the Caching realm and the alternate security realm (in this case, the LDAP V2 security realm).
