openssh unix dev - Nov 2004 - Searching for original UID at remote (sshd) host

Hi,

does there exist a functionality in the current code, which allows the 
setting of an environment variable at the server side that represents 
the original user id at the ssh client side. The intention for that is, 
that i will know who the real user at the ssh client side is, if the 
user sets the option "-l <user>" in the ssh command. In the
current
code, I found only the options.user  structure, which contains the 
username for the new session, but there is no parameter  for 
transferring the original user name if the -l option is used. I need the 
original UID for an auditing mechanism at the server side.

Example: user1 at host1>ssh host2 -l user2   : host2 does't know, that 
user1 has made the ssh connection from host1

No, the server side would have to trust the client to not lie about the
uid anyway.

If you are happy with this trust, then you could probably cook something
up with the existing environment passing support (see SendEnv and
AcceptEnv in client and server config manpages)
