[Users] Secondary Group Association

[Tavis P]

I'd like to be able to have OpenSER run with a secondary group
association other than its primary group (set in openser config as
group=groupname, or if group= is left out then uses the primary group in
/etc/passwd)


I've tried setting group= twice however then it only takes the last
assignment.
I've tried leaving out any group= definition in openser.cf however it
then only uses the primary group in /etc/passwd


Is it not possible?  If so then what changes would be required to make
it work?
