ssh-agent and TMPDIR

[Jerome BENOIT <g6299304p@rezozer.net>]

Hello List,

I have just built and installed openssh 1:5.8p1-3 from sid on my squeeze box
in order to getssh-agent to honour $TMPDIR.
In /usr/share/doc/openssh-server/changelog.Debian.gz I read:

    - ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
      temporary directories (closes: #357469, although only if you arrange
      for ssh-agent to actually see $TMPDIR since the setgid bit will cause
      it to be stripped off).

How can we make $TMPDIR be seen by ssh-agent ?

Thanks in advance,
Jerome
