Hi, I'm new and found my way here via WAR's blog post.
Big +1 for TACACS+ support.
I manage a bunch of cisco routers and now have half a dozen or so vyos routers in the mix too. I need to grant junior admins rights to these while limiting their ability to break stuff and currently use TACACS+ for this with the cisco routers we manage. I would love to do the same for the growing fleet of vyos virtual routers.
