Public bug reported:
pam_group is a pam module that grants group membership to users on a
per-session basis (http://www.linux-pam.org/Linux-PAM-html/sag-pam_group.html).
We would like to use it to grant access to epoptes for many users. However,
epoptes does not honor this group membership. It seems, epoptes does not check
for groups granted by pam_group, just those defined locally in /etc/groups.
See attached screenshot: As seen from the output of "groups", user "kup" is
clearly a member of group "epoptes". However, epoptes complains that he is not,
and refuses to start.
Group membership to "epoptes" was granted to "kup" by pam_groups. Other users
listed in /etc/groups can start epoptes.
This seems to be a bug in the way epoptes checks for group membership.
