Comment 4 for bug 685655

Output of polkitd when trying to authenticate in time-admin (the password dialog is never displayed):

** (polkitd:1752): DEBUG: system-bus-name::1.56 is inquiring whether unix-process:2283:1752924 is authorized for org.freedesktop.systemtoolsbackends.set
** (polkitd:1752): DEBUG: user of caller is unix-user:connor
** (polkitd:1752): DEBUG: user of subject is unix-user:connor

Authenticating in nm-connection-editor works as expected, and polkitd logs this instead:
