Ok, I worked with IBM support on this a bit and I think we've figured out
what is happening.... although I'm kind of distressed about the cause.

My CGI program switches user handles so it can operate as the authenticated
user.  Here's the basic logic ...

1. Program starts, user profile is QTMHHTTP
2. Retrieve current user from the PSDS and save it.
3. Switch to the user profile identified in the REMOTE_USER environment
variable.
4. Do work
5. Switch back to the saved user profile (QTMHHTTP)

This, however, does not work properly ... something about the QTMHHTTP user
not having the necessary authority to do a recv.  If, on the other hand, we
switch back to QTMHHTP1 instead ... our program works.

This flies in the face of the concept of leaving the execution environment
in as close to the same state it was when the program started ... and it's
got me just a bit concerned.

Anyone know why I would need to switch to a different user profile when my
CGI program is done?

Thanks!
