To be able to be admin in each computer, I use pam_group feature to select additional groups for user. (/etc/security/group.conf). Login directly on the console give me good group membership (the one defined in group.conf), but login from lightdm results in an error message in auth.local: pam_group(lightdm:setcred): unable to set the group membership for user: operation not permitted. Of course, the group membership is not set as it should.
