Well, this has nothing to do with struts itself. Well, the basic thing to do is to have a form with a username and password fields, and it submits to an action that authenticates the user. The action authenticates the user by comparing the username and password with those in database or LDAP, preferably with encryption. Of course a lot of other things can be done, like using JAAS, ACEGI, using a central authenticating server like CAS.
