What is single sign on

Single Sign-On means having one entry point into the portal that requests user's authentication. As you move throughout various applications within the portal, the user is not required to login again for each page (or section or application).

The main advantage is that the user does not get frustrated having to log in many different times. In some instances, the ID and password may change from application to application. This would require the user to know many different ID/password combinations. Not to mention the nusance of typing it all in at every point.

Security should be discussed during the Initiaion phase of your development. You could do some really simple things like storing the ID/Password as a cookie, or passing it as a tag in the URL. Each of these may not be secure enough for your portal. You may want to look at using Active Directory authentication if you are using a Windows 2000 platform.

I go with ink about the Single sigon. Microsoft uses the single signon feature in their website. Check this link. it discusses about the security issues:
