After an upgrade from a proxy server to an ASA, the users are prompted to login again

Core issue

This happens as the ASA does not support transparent authentication.


Proxy servers support transparent authentication, but when an ASA is used, the users have to login again. This happens because the ASA does not know about the user credentials.

In order to get the user credentials, the ASA has to communicate to a RADIUS server to confirm the user password.
