Re: Problem with authentication against FreeIPA

22 Aug 2019

      Hello there good people of FreeRadius,

I got a bit of an issue setting up authentication between <whatever_service_will_use_radius> and the backend FreeIPA cluster.
Been trying different approaches for a while but it keeps failing when it tries to do a bind with the user to LDAP. I'm pretty sure there is something small but fundamental I'm missing here and have spent way too much time trying to figure it out on my own.
Below is the debug log which should give you all the details but please feel free to ask if anything there is unclear.
