am missing any configuration for mapping

realm as below;

<Realm className="org.apache.catalina.realm.JNDIRealm"
    connectionName="uid=admin,ou=system" connectionPassword="secret" authentication="simple"
    connectionURL="ldap://localhost:10389" userSubtree="true"
    userBase="ou=User,ou=ActiveMQ,ou=system" userSearch="(uid={0})"
    roleBase="ou=Group,ou=ActiveMQ,ou=system"
    roleName="cn"
    roleSubtree="true"
    roleSearch="(member={0})" />
Solution

  • Role Search pattern was wrong , i correct it as 

    roleSearch="(member=uid={1})

    Now it works for me thanks
