[Freeipa-users] SSH access to only specific hosts useding ssh keys

[Tym Rehm]

So I want a user "bob" to ssh into server1 as the username of "support"
with support at server1, but not let Bob ssh into support at server2. I have
Bob's ssh public key added to the support user. I can block Bob from
server1 or server2 with HBAC, but I have to add support to both servers and
since Bob's keys are added to Support. The support account is able to ssh
into both servers.

I've looked into ID view, but I'm having troubles find a good document on
how to setup ID views.
