[Bug 1061277] Re: ssh ignores ssh_config

[Robie Basak]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Indeed it should generate an error on startup if you get that wrong, and
it does for me:

With openssh-client 1:5.9p1-5ubuntu1:

$ ssh localhost
/etc/ssh/ssh_config: line 54: Bad configuration option: AllowUsers
/etc/ssh/ssh_config: terminating, 1 bad configuration options

Marking this as Incomplete for now. If you can provide accurate
reproduction steps then please add them to this bug and change the
status back to New.

I'm also marking as Importance: Low as it affects "unusual end-user
configurations" only, as per the bug importance guidelines. This is
unlikely to get fixed in Ubuntu without it being fixed upstream first,
so if you'd like to see it fixed it would be best to file a bug upstream
once you have detailed steps to reproduce.
