Captive portal with login/password random MAC problem.

    Hello,

    I have a problem with a captive portal using login/password authentication (without ClearPass, configuration on virtual controllers managed by Aruba Central / Conductor).

    When I have two different captive portals on my VLAN - one with only email confirmation and the other with login/password - the second one does not work for devices using a randomized MAC address. When I set a fixed (real) MAC address on the device, everything works correctly.

    The symptom is that the client receives the role but does not get an IP address; in practice, the DHCP request does not reach the DHCP server. This was tested both with an external DHCP server and with the built-in Aruba DHCP.

    The network is open (no OWE). 

    Has anyone else observed similar issues?

    AOS 8.13 with APs650

    If you're managing the devices using Central, have you tried using Cloud Guest instead?
