Corporate single sign-on solution based on Microsoft ADFS 2.0

Year: 2011
Purpose: To provide users with the single sign-on point for the access to a number of corporate applications.

Description: Single sign-on is a kind of an aceess control system that provides user with permission for multiple independent software systems. With single sign-on user logs in only once and gains an access to all systems without being prompted to log in again at each of them.
Intelligence-soft engineers developed and implemented custom single sign-on solution protecting a number of corporate web applications with united authentication/authorization system. Solution is based upon Microsoft Active Directory Federation Services vers.2.0. Hardware configuration includes 3 servers running Windows Server 2008 R2:
  • ADFS Proxy Server published to internet and serving web clients with login form and several supporting applications
  • ADFS Server itself with Active Directory (about 500000 user accounts) and Federation Services handling clients authentication requests
  • Application server running a number of ASP.NET 4.0 applications protected by the single sign-on system
In addition a number of Windows Server 2003 machines and a number of application servers running non-Windows legacy applications (Java, php) are also integrated with the system in such a way that user, who passed authentication once, may navigate between different applications located on these machines without individual login in each of them.
The convenience for the users is not the only advantage of the single sign-on system. It also provides system administrator with single place for tracing users behavior - instead of scanning many log files located on individual servers for each application, sysadmin may get all required information in a single sign-on system log.
And finally the system provides addiitional level of security because sensitive information (username, password, e-mail and other personal data) is stored in highly protected storage - Active directory, that is much more secure than individual user databases in each application.
Implementation of single sign-on solution included the development of several custom web applications such as:
  • User self-registration wizard
  • Edit My Account application providing users with an easy-to-use tool for the management of their personal data
  • Collection of custom Login forms
  • Administration utility for the management of user accounts stored in Active Directory
  • My Account Dashboard application providing user with simple navigation across different other applications running under the same single sign-on umbrella.
  • A number of GUI-less layer applications intended for the work as intermediaries between the single sign-on system and various legacy 3-rd party applications in order to accommodate their authentication protocols.

Programming languages and technologies used: ASP.NET, C#, ADO.NET, MS Windows Server 2008 R2, MS SQL Server 2008, Active Directory, ADFS Services, WIF, SOAP, SAML
