All of a sudden in 11.10 I am no longer even though administrator able to mount New volumes such as pen drives. etc. Also my User Account unlock is now greyed out. If I log in as a guest I can mount volumes but not as administrator. Everything else such as root etc seems ok its probably to do with the grayed in unlock on the user account. Ideas please.
Update: If I hover mouse over padlock even though I am logged in its says System policy prevents changes Contact your system administrator.
