Abstract: A method for sign-on and sign-out for a computer system. The method includes receiving a first sign-on request for the computer system and obtaining, from the first sign-on request, a first user identifier where the first user identifier corresponds to a first user for the computer system. The method then includes obtaining, from the first sign-on request, a first uniform resource locator (URL) and determining whether the first URL includes a first root name for the computer system. When a determination is made that the first URL includes the first root name for the computer system a first cookie associated with the first user is issued and a first sub-domain name is obtained from the first URL. Also, a second cookie may be issued associated with the first sub-domain name and, when the first cookie and the second cookie are issued, the first user may sign-on to the computer system. In one or more embodiments, the method may include receiving a sign-out request.
