  ****************************************************************
  If ibm-allGroups is configured VMM explicitly validates each
  group that is being returned from the LDAP as a value of the
  ibm-allGroups operational attribute to make sure that each and
  every entry that is being returned is actually a group not a
  user. This additional validation requires a JNDI call for each
  of the entries that needs to be validated which will have an
  impact in the overall login time.
  

Problem conclusion

• VMM no longer does the additional validation of the groups
  that are being returned whenever ibm-allGroups is configured
  and returns the data that is being returned from backend LDAP
  directly to the user.
  
  The fix for this APAR is currently targeted for inclusion in
