So users are going to the clientless portal on a ASA-5525 and entering their LDAP credentials without an issue. Once authecticated though, they get an error that says Connection failed Server <Portal name> unavailable. and have an option to hit back, Home or Logout. Hitting Home does nothing and Logout works as expected even providing the "Thank you..." message.
I have searched the web and tried all of the suggested fixes and got no where. The platform is an ASA 5525 runnin code level 8.6.(1)2
Any ideas what I can/should be looking at?
