This is the first request I've seen for TACAS support. Since IPA is a
unified identity solution at it's core it's not clear to me at the
moment what advantage there would be to TACAS other than as emulating a
TACAS server for legacy and/or 3rd party products which depend on the
TACAS protocol. If one wants to set up a TACAS daemon there is a
reasonable chance it could validate against IPA (more investigation
would be needed) and this would give you something which provide TACAS
protocol but be backed by IPA and it's management tools.
We do have plans on our roadmap to support RADIUS which is often used as
an alternative to TACAS.
But perhaps I haven't fully understood your request. So let me rephrase
it and see if I have it correct. You want something on your network
which speaks the TACAS+ protocol but whose identity management is backed
by our IPA server. Is that correct?
