Petro123listtoview,
Намек что у тебя уникальный случай и тебе нобелевку дадут?
SSO есть для этого.
что конкретно из этого у нас есть? правильно, ничего
Single sign-on (SSO) (i.e. accessing the application without providing a username and password) will occur if all the following are true:
The client computer and the server are part of the same Active Directory domain.
The user session on the client computer is a user from the AD domain.
The client computer has access to a domain server (i.e. the server responsible for the user login)
The browser is Internet Explorer.
The URL used points to the FQDN of the server (i.e.
http://SERVERNAME.DOMAIN.NAME/ not just
http://SERVERNAME/
The authorized users must have read access to the application directory if you are using impersonate. The application will be running with their credential basically. (more details in the MSDN article)
