Error description

Server.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: All WebSphere Application Server users       *
*                 using LTPA authentication and assigning      *
*                 users to one or more groups.                 *
****************************************************************
* PROBLEM DESCRIPTION: WebSphere was validating all groups     *
*                      returned from LDAP for a given user.    *
*                      This validation was unnecessary as the  *
*                      information had just been received by   *
*                      LDAP and was unlikely to change.  If    *
*                      LDAP queries for group information      *
*                      took an excessive amount of time the    *
*                      admin server load is high, this could   *
*                      add a significant amount of time to     *
*                      the authentication process.             *
****************************************************************
* RECOMMENDATION:                                              *
