domain

Hi,

I have a requirement to login to portal, and access different applications in different servers from the portal on click of their corresponding links. Here I have to pass the login credentials to the individual applications and access without logging in second time. i'. e., I have to implement Single sign on and should be able to access cross domain applications.How I can do it in mvc.net, as all my applications are in mvc.net.

Any help will be appreciated.

Thanks in advance.

What I have tried:

I have read a lot of articles available online, but some of them are for a single domain, some are for classic asp.net, etc..

I can implement it using Azure Active Directory, unfortunately I can not do that due to some email id related constraints.

I have tried the following, but nothing worked for me:
