I have two groups defined in /etc/groups as:
  file-owner:x:300:user
  user:x:400:

when I run the command id on the terminal, I see file-owner is added as an additional group.

  # id user
  uid=300(user) gid=300(user) groups=300(user),400(file-owner)

However, running id from a script started bu SLM with <SLM:user>user:user</SLM:user> gives:
  uid=300(user) gid=300(user)


Is this a known bug?





This is causing me a problem because I cannot read a configuration file that is owned by the user/group file-owner, with
 zero permissions for others

   ls -l /tmp/my-configs.txt         
   -r--r-----   1   file-owner   file-owner   1054552  Jun 11  12:22  /tmp/my-configs.txt

I run a process with id user:user but I cannot read the configuration file owned by file-owner.
