Doc Type: Known Issue
Doc Text:
When a user password is used to lock a console with vlock, the console can only be unlocked with the user password, not the root password. That is, even if the first inserted password is incorrect, and the user is prompted to provide the root password, entering the root password fails with an error message.

Description Petr Bokoc 2013-01-14 13:06:42 UTC
Description of problem:
vlock doesn't unlock the console with root password, only user password

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. lock a console using vlock as an user
2. when prompted, enter wrong or blank user's password
3. vlock then asks for root password, enter the correct one
Actual results:
console stays locked, vlock outputs a "wrong password" message

Expected results:
console should be unlocked

Additional info:
- if you use vlock when logged in as root, it asks for the root password twice. In this case it works, vlock accepts the second password even if the first one was incorrect.

- the same problem exists on fedora 17: vlock-1.3-31.fc17
