This project is read-only.
SSO within multiple ASP.NET applications in different sub-domains

Single Sign On Between Multiple ASP.NET applications with same domain but different sub-domains and all of them using forms authentication

In case you still find the SSO not working, it can be due to different version of .NET framework and so different cryptography.
make sure you have following with correct .net framework version in web.config of all applications
1) compatibilityMode=”Framework45” configured in machinekey element
2) <httpRuntime targetFramework=”4.5″ />
