CMX Connect Experiences Web Auth Form Login

Is there any way to validate Username and Password with external Radius, LDAP, Database or any other Repository?

I mean, allowing users (already existing in any other custom in house system) to connect through the Wi-Fi login process using the CMX web portal with their existing username and Password in that other system, via Radius , LADAP, API, OAUTH ....

And not only being able to connect authenticating only with linkedin, twitter and Facebook, or authentication with CMX local defined users.

Please see "Property Management System (PMS)" in below document.

Cisco Connected Mobile Experiences Configuration Guide, Release 10.2 - Cisco

Starting from 10.2.2, CMX should support the integration with PMS systems using “Unilink Rest Management”. CMX will communicate with a Nevotek server component. The connection to Nevotek is to allow CMX to connect to any PMS that they support. Unilink in the product name of the product offered by Nevotek the company. http://www.nevo-med.com/unilink.html

This's somehow what I was looking for !!

I would like to know (if it is possible) how this can be done, connecting with CMX but using any custom external user Database. Even if programming or scripting needs to be done. I used to work with LWA with external web server.

How CMX communicates with any server component for login users?

Also, see the following Design Guides.
