Can anybody share what all are the different options available to set in 'Rd-Auth-Type' attribute?
My requirement is to push captive portal page into default browser, other than CNA or CPA. By default it required only a lightweight browser to serve captive portal, so that most of the cases it'll go to CNA/CPA.
Also I neet it to be opened automatically.
If anybody familier with some other options than Rd-Auth-Type also can share.
