box with a message (OK or OK/Cancel) and/or launch the login prompt if the current user
does not have the requested privilege.

BridgeVIEW user does not have the requested privilege, and the input

appears when the OK button in the message dialog box is pressed.

the current BridgeVIEW user does not have the requested privilege.
user has privilege is TRUE if the current BridgeVIEW user has the
requested privilege.

requested privilege, prompt for login was TRUE, and the login dialog box
was cancelled.
