Further searching of the forum shows this:

However, my desktop's version of 
/usr/share/polkit-1/actions/org.freedesktop.udisks2.policy doesn't have 
<action id="org.freedesktop.udisks2.filesystem-mount-other-seat"> and I 
don't know enough to be sure where (if anywhere) to modify.  However, it 
seems like a good idea to pass this on because somebody out there will 
probably know what's needed, now that we have an idea of where to look.
