Comment 8 for bug 880104

Just installed a 12.04 test VM and I still get the error message in /var/log/auth.log:
Mar 8 23:50:00 lightdm-test lightdm: pam_group(lightdm:setcred): unable to set the group membership for user: Operation not permitted

I also get an error message about ldap server not available:
Mar 8 23:50:01 lightdm-test dbus[736]: nss_ldap: could not search LDAP server - Server is unavailable
however I managed to connect ssh on the vm and I get all my additional groups...

I suspect a change in pam handling as "su - " does not get the group anymore... quite strange...
lightdm and su can't fetch my groups whereas ssh can...

I can post my pam files if needed.
