[Bug 1380084] [NEW] SSH client requires SSH_AUTH_SOCK=0 will not work without it, can't use key auth without SSH_AUTH_SOCK=0

[Nathaniel Homier]

Public bug reported:

I expect that when using key based authentication I do $ssh user at 0.0.0.0 I expect to be asked for the key password.  Instead I get Agent admitted failure to sign using the key.
Permission denied (publickey).

Using SSH_AUTH_SOCK=0 solves the problem allowing me to be asked for the
key password.

What should happen is that I should not have to specify SSH_AUTH_SOCK=0
on the CLI, I should only have to type $ user at 0.0.0.0
