Description samurai.no.dojo 2017-11-16 11:47:44 UTC 
/bin/groups (sys-apps/shadow-4.5) returns list of supplementary groups doubled.
but /usr/bin/id works as expected.

Reproducible: Always

Steps to Reproduce:
1.run /bin/groups user

Actual Results:  
wheel uucp cdrom video cdrw usb users mail plugdev vboxusers wireshark wheel uucp cdrom video cdrw usb users mail plugdev vboxusers wireshark user

Expected Results:  
wheel uucp cdrom video cdrw usb users mail plugdev vboxusers wireshark user

This also breaks app-admin/puppet-agent which relies on groups for is "user" resource.
I can reproduce this on three machines.

I now have sys-apps/shadow-4.5-r1 and I cannot reproduce this bug anymore.

I do still have this problem even with sys-apps/shadow-4.5-r1
Comment 8 samurai.no.dojo 2018-08-28 13:27:54 UTC 
It does not happen with sys-apps/shadow-4.6
Comment 9 Francesco Turco 2018-08-28 14:32:55 UTC 
It's strange but I can now reproduce this bug again with shadow-4.6.
Comment 10 Francesco Turco 2020-03-17 10:25:17 UTC 
With sys-apps/shadow-4.8.1-r1 everything seems OK. Can anyone else confirm?

With sys-apps/shadow-4.6, I got the following :

user@user ~ $ /bin/groups user
wheel audio cdrom video usb vboxguest user
