How do I implement a Single Sign On (SSO) or something similar in functionality to work with multiple web applications using the same .NET 3.5 Membership database on MS SQL server 2005?
Some of the web apps use the same second-level domain names e.g. a.site1.com and b.site1.com, however one has a different second level e.g. www.site1.com
The desired functionality is for a single logon and authentication that will 'travel' across the multiple web applications.
Thanks in Advance!!
