I have configure the webvpn on ASA 5520 using ASDM version 5.2. It works perfect with local authentication but it is not working with Radius. The radius server test is OK on the aaa server configuration page. however, when I try to log in with web access, I get a login failure. the suprising part is that even though I get a login failure, it shows authenticated on the radius server and also the syslog message of the ASA show authentication successfull.
