Re: How to make sshd inherit environment variable from its parent process?

That's not acceptible for this case because I want to control user's 
resources based on user's job types, which is determined by a dynamic 
environment variable called "ENVIRONMENT" when jobs were submitted to 
the job scheduler [grid engine].

I couldn't find any other way to set this variable without intervening 
user's own environment so far.
