Ahhh... Have'nt pay attention to these features in 17.3.1:
From Cisco IOS XE Amsterdam 17.3.1 onwards, to control the HTTP and HTTPS requests sent to the web authentication module, new commands that are listed below are introduced under the global parameter map parameters.
The following commands were introduced:
secure-webauth-disable
webauth-http-enable
Now at least i got the login webpage.... Thinks i will do from here.....
Thanks Kasper
