Description Giulio 'juliuxpigface' 2015-10-03 21:58:45 UTC 
Description of problem:
I found what seems a corner case where lxdm allows the login even if the provided password is wrong. This might not be a true bug, but in my opinion the behavior of lxdm in this situation is somehow strange.

Version-Release number of selected component (if applicable):
lxdm-0.5.1-6.D20150806git17ac3772.fc23.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create an user without password.
2. Login through lxdm with that user.
3. Provide a password for the login.

Actual results:
lxdm allows the user to login.

Expected results:
In my opinion (but I might be wrong), lxdm should refuse the login. The real password is blank, so if no blank password is provided, the real combination of "login name + password" is not actually matched.

Additional info:
Fedora 23 Final TC1 (x86_64) on qemu-kvm.
