iControl REST with RADIUS Authentication

I'd like an answer to this as well, it looks like the REST API only works with local auth.

Created a case with this topic and the F5 engineer told me, that it only works with local auth. I'll create a RFE (request for enhancement) which will be forwarded to the escalation department by the F5 engineer.

I couldn't get iControl to accept TACACS+ either (tried it on v11.5.2)

Token based auth is now enabled in 12.x. See iControl Auth with F5 Rest API
