Hi, I upgraded for one of our products the SSH server to the portal OpenSSH 7.7p1 release. While testing I observed a change in the behavior for expired passwords. The commit 7c8568576071 ("upstream: switch over to the new authorized_keys options API and") dropped the 'allowed pty' option when the password has expired. By adding this hack here, I got it back to the old

Maybe I am not testing the signin correctly. Here is what I am doing. I sign into the client/workstation (hereafter referred to as C/W) via ssh as the local "admin" from another C/W so I can open many terminals to tail log files. Then "sudo -i" into "root". All testing is run as "root". When I sign into "root", I see this: > admin at lws4:~$

Hey everyone, I wanted to add support for denying PTY allocation through OpenSSH. I'm not certain if this is quite thorough enough for all cases, but for me it might work for the moment. I know that you can currently do this through authorized_keys, but as far as I know that only works for an actual key. In my use case, I wanted a user with no password which is forced to run a specific
