[Bug 1771011] Re: Doesn't accept environment variable with underscore in its name in AuthorizedKeysFile

[Joshua Powers]

Hi, thanks for taking the time to file a bug. Based on that last message
from SSH it makes me wonder if the syntax you have is correct.

1) Can you confirm PermitUserEnvironment is set to yes in your
sshd_config?

2) Can you provide more details of the line in question in your
authorized keys file? For example, if I add:

environment="FOO_BAR=1" ssh-rsa AAAAB

then connect:

root at x:~# env | grep -i foo
FOO_BAR=1

This question may also be better suited for the community forums as it
is more of a support issue.
