I have installed FreeRADIUS and FreeIPA on the same machine running Fedora 33. IPA is working as expected and can have clients join and authenticate. LDAP command line tools (ldapsearch, ldapmodify) can successfully bind to the server both locally and over the network using the same credentials.
But when I try to start radiusd (either in debug mode or as a daemon) I get the error "Server is busy". CPU and RAM usage when testing is less than 10% so I don't think the server is overloaded. Below is the LDAP instantiation log. I have tried to find a log of attempted LDAP binds but have been unsuccessful.
Any advice would be greatly appreciated!
