When locking console in a virtual machine the vlock seems get to endless loop and print only the following message:
The pts/1 is now locked by pkis.

It is not possible to enter password at all and it continues until it is killed from another terminal.
It was tested on virtual machine only, but it is expected to work.

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

How reproducible:

Steps to Reproduce:
[pkis@rhel7 ~ ]$ vlock 

The pts/1 is now locked by pkis.
Authentication failure.

The pts/1 is now locked by pkis.
Authentication failure.


From other terminal:
[root@rhel7 ~ ]# killall -9 vlock

Please enter the password to unlock.

This fix appears to be incomplete - while the missing configuration file has been re-added, vlock doesn't appear to be calling pam_setcred() after successfully verifying the user's identity as the old version did (see also bug #913311).

VERIFIED on kbd-1.15.5-7.el7.x86_64
tested on tty and ssh with success on both

The problem I mentioned in comment #4 appears to be causing bug #1029374.  Does that fix belong here, or in a new bug?
Comment 7 Tomas Dolezal 2013-11-19 06:35:55 EST
Hi Nalin,
problem described in comment 1 is fixed, this blocker bug has to be verified by the end of this week.

I was unable to reproduce your bug 913311. Please try to reproduce on kbd-1.15.5-7.el7.x86_64 and then be sure to clone the bug to RHEL7 product. If I had succeeded, I would have done that.
