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

Hi,
I am using OpenSSH 4.2p1.
I need to make sshd process to inherit some environment variables (EVs) from its parent process.
It looks like sshd process only inherits a limited number of EVs: HOME, LOGNAME, MAIL, PATH,PWD,SHELL,SSH_CLIENT,SSH_CONNECTION,TZ, and USER.
Is it possible to make the child sshd process inherit some EVs from its parent process? Those EVs are dynamically set after submitting a job.
Please let me know how to do it if it's possible.

26847 /gridware/n1ge6u6/bin/sol-sparc64/qrsh -nostdin -inherit hes-hpc4 sleep 120; ec
26850 /usr/local/bin/ssh -x -n -p 59527 hes-hpc4 exec '/gridware/n1ge6u6/utilbin/sol-
26848 sge_shepherd-412 -bg
26849 /usr/local/sbin/sshd -i <<< Why the sshd process inherits only some EVs from its parent process?
26852 /usr/local/sbin/sshd -i
26853 /gridware/n1ge6u6/utilbin/sol-sparc64/qrsh_starter /gridware/n1ge6u6/default/sp
26854 ksh -c sleep 120; echo BATCH;ulimit -t
26855 sleep 120
The parent sge_shepherd process sets some environment variables dynamically. Onne of them is called "ENVIRONMENT".
Using the ENVIRONMENT variable attribute [ either interactive or batch], users' computational resources can be set differently.
Since sshd didn't inherit the ENVIRONMENT variable, the variable didn't get passed to its child process, qrsh_starter as shown above. So resources doesn't get set properly.
Thanks,
