Login with no password won't work

[Fabian Thoma]

Trying to login on accounts without password does not work

debug info from lighdm:

PAM said the password was valid:
pam_authenticate(0xdd9b80, 0) -> 0 (Success)

But then failed on the next step:
pam_acct_mgmt(0xdd9b80, 0) -> 7 (Authentication failure)

Is that account locked?

I have a similar issue but not exactly same. In my case if I entered a wrong password for the user the first time and then enter the right password I couldn't login. Everytime I would get wrong password.

what is with login on the livecd?

Unmarking as affecting us since we've moved to a GTK/Clutter based greeter.

I think this might have been an issue with a specific greeter. I have tested Rev 31 with a test account with an empty password field in /etc/shadow, using the "simple" greeter, and the user logged in just fine.

Closing.
