I have two Ubuntu 12.04 systems, one a desktop, and the other running as a NIS/NFS server (a desktop with lightdm disabled). When I login, I get the dialog (not error) "Authentication is required to change user data" The Details section of the dialog says "org.freedesktop.accounts.user-administration"
Any help helping me figure out how to make this dialog go away is appreciated.
BTW, not entering the password has no effect whatsoever.
