MIKROTIK - set proxy authentication

Is it possible to set mikrotik authetication to be used for set the connection of other applications to internet?

For example connect miranda IM using mikrotik proxy server:

I’ve tried:

    • to use hotspot login


    • bypass hotspot for selected MAC/IP (IP Bindings rule and and login without credentials)

but it doesn’t work..

My scenario:

    • one mikrotik in the AD domain


    • INTERNET/LAN interface


    • no DHCP on mikrotik


    • one hotspot with users and user roles created


    • web proxy on port 3128


    • masquerade for port 3128

Aha, it seems mikrotik doesn’t allow that:

Is it true?
