AP Openwrt managed by Mikrotik routeros

Hi, We have a customer who has about 20 Ubiquiti Picostation M2 Access Points whose native firmware has been replaced with Openwrt Backfire 10.03.1 by the previous company that managed the assistance.
I wanted to know if there is a Mikrotik hardware device that in addition to performing the functions of WLC (wireless lan controller via Capsman, therefore unique SSID, management of each individual AP, etc.) also allows the implementation of a captive portal with the following types of authentication:

  • Internal db
  • Radius
  • Active Directory
  • Social (Facebook, Twitter, Instagram, Google Gsiute, Google gmail
  • Mail
  • sms

Thank you

Captive portal can be aranged by mikrotik, but none of MT Devices cannot be a controller for OpenWRT.

ok, then in this case is it possible to flash these ap with os router so that they can be managed by a Mikrotik device?

UBNT devices are not supported by RouterOS, only think that you can do is to install them back AirOS and then to manage them with UNMS and Unifi Controller

ok thank you. regards
