[jcifs] Role based NTLM

[Manju_Panjwani at DadeBehring.com]

Newbie question-
I am trying to check whether user belongs to a particular group using  the
jci-fs extension filter

    http://sourceforge.net/projects/jcifs-ext/

I have made the required changes to web.xml file.
but the call to the method isUserInRole("GROUPNAME") always returns false.
For e.g. the user belongs to Administrators group but
request.isUserInRole("Administrators") always returns false
Do I have to configure the roles in TOMCAT as well? What else do I need to
configure?
Please help.
Thanks
