Hi,
The STAF PROCESS service code does not do anything differently for
different Linux systems.
What exact versions of Linux are you seeing this issue on? What is the
output from "uname --a" and "cat /etc/redhat-release" on these Linux
machines?
Are you sure that on these Linux machines that the PROCESS service's
PROCESSAUTHMODE is set to "None" and not "Disabled"? Because if not, the
command run via the PROCESS START request with the USERNAME option will
not be run as the specified user and will be run as root (with no error
message).
Provide the output of running the following commands (substituting staf1e
with the hostname/IP address of your Linux machine and substituting "test"
with the username that you want to run the process as.
# STAF staf1e PROCESS LIST SETTINGS
Response
--------
Default Stop Using Method : SigKillAll
Default Console Mode : Same

Process Auth Mode is Disabled
}

work?
Hi Sharon,
Well, it seems to work on most platforms. There is no problem on about
30 different UNIX and Linux systems, and several of them are Redhat;
there are just 3 of them that don't change the user ID. I suppose I
can start looking in the code for the process service; I just hoped
maybe somebody had seen this problem before.
When/if I find the solution, I'll let the list know.
