****************************************************************
There was a problem in Authenticating lookup using LTPAToken.
Although the same token is used in requests,  cached Subject was
not found.  As a result, Liberty was always calling LDAP to
retrieve user information to recreate a new Subject, causing the
performance issue.
In security trace (com.ibm.ws.security.*=all) ,
findSubjectByTokenContents always finds null even when same
user's token was used.
