admin authorization for management

[Charles Smith]

Hello,

If I run the update-manager or other graphics front-end for apt-get, I'm prompted to enter my own password.  I'd like to have to enter the root password instead.

There's this Authorizations dialog.  Is that the way to do what I want to do?  Change org.freedesktop.self from Authorization to "Admin Authorization"?  Unfortunately, I've already disabled the administration rights of the user in question.  How can I run this dialog from the command line?

TIA,
