I am using JBoss Portal 2.6.3. We have a requirement to develop a Portal application, where authentication information should be windows login information.
If a user has logged in to his windows machine, as soon as he loads the link to Portal, he should be automatically authenticated and taken to the Portal home page without asking any login credentials. His username needs to be displayed on the home page.
How can this be achieved with the JBoss Portal security mechanism? I believe this could be possible in a normal web application and can the same mechanism can be probably used here?
