title: Domino Web SSO : Invalid username or password was specified
body: <p>I configured a Web sso for my domino server.  When I opened the .xsp page, a yellow background HTML log-in form appeared and asked me to type my user name and password.</p>
  
  <p>But after I entered the correct user name and password(I'm sure they are correct), this yellow log-in form asked me to type over and over again!</p>
  
  <p>I was totally confused. Anybody knows what's the problem? Thanks in advance.</p>
