RequestTTY option is not respected when declared in .ssh/config

[humboink]

Using this .ssh/config file on a up-to-date ubuntu 12.10 64bits using ssh 1:6.0p1-3ubuntu1

  Host xxxx.xxxxxx.com
  RequestTTY yes

$ ssh xxxx.xxxxxx.com screen -x
Error: "Must be connected to a terminal." <--- config option is not respected !

While entering the same config directly in the command line works nicely :

$ ssh -o "RequestTTY yes" free.zboubi.com screen -x
Works ok

$ ssh -t free.zboubi.com screen -x
Works ok

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

I have been able to reproduce this on 12.10 (openssh-server 1:6.0p1-3ubuntu1). My gut feeling is that there is some kind of catch that we're missing but I have been unable to find anything. So far it does seem like a bug to me.

For a proper fix, the next step is to identify whether this bug is present in the upstream project, introduced in the Debian packaging or introduced in Ubuntu's modifications. If Ubuntu hasn't introduced the problem, we should get a bug filed in the appropriate bug tracker. Are you able to help with this, please?

This should probably be Confirmed rather than Triaged since we don't know what we need to do to fix this yet.

I did the following test, compiling the source code distributed on openssh.org:

openssh-6.0p1 : bug is present
openssh-6.1p1 : bug has been corrected, and contains the following Changelog

Can the openssh package be upgraded to 6.1p1 on ubuntu 12.10 ?
