No. For example, if smart card authentication is in use, the PIN entry field should not be shown until and unless the smart card is inserted in the reader. If challenge-response authentication is in use, it would incorrect to display the response field until the user ID has been entered and a challenge presented. There are a number of scenarios in which it is just wrong to present a password field. It is correct for the Unity lock screen to not always displaying a password entry field when it has not been instructed to do so by the underlying auth mech. Any authentication dialog that does so, and actually authenticates the user as a result, possibly has a critical security vulnerability. It would be a good idea to audit your local authentication setup if you are seeing this bug. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
