[swapnil rawat]

HI All,
      I am new to jcifs . I am asked to achieve SSO in my application
      I am using jcifs ntlm http authentication protocol.
      I am successfully able to apply SSO to my application but the
only problem    is  i have to provide username and password into my
web.xml file.

How could i achieve SSO without configuring the username and password
in my web.xml file
any help is truely appreciated
Thankyou
