Captive portal - external auth

OV2500 enterprise, anyone tried to configure captive portal, (UPAM portal page) but using an external authentication source (NPS server) There is the option in the config to choose an external source but it does not show up as it having changed when applied ?

Thanks

Hi, If I'm not wrong it is not possible. The upam does not return the credentials entered on the portal to the NAS for authentication against an external NPS. The credentials are validated by UPAM against its guest database. I guess it is done this way because of the licensing model for guests. But, I agree with that UPAM should support external databases for guest. This is a handicap for us at some end-customers.
