Build and Implement A Single Sign-On Solution

Single sign-off

Without a unified strategy, developers re-implement custom security for each network application. This can result in a variety of scalability and maintenance problems. Single sign-on solutions can be that unified framework for security and authentication, alleviating much of the burden on users, administrators, and developers.

The concept of single sign-on, the technologies, and the implications for users and administrators are complex, so I have only scratched the surface in this article. But I have provided you with some practical ways to implement a single sign-on scheme using the proven CAS application from Yale University, and have also detailed a method to extend this technology so you can use it to authenticate users to a LDAP server (specifically, to an Active Directory Server using the Kerberos protocol).
