[Pkg-xfce-devel] Bug#667900: [lightdm] Does not start Xsession for user without password

[Marek Straka]

Package: lightdm
Version: 1.0.9-1
Severity: normal

--- Please enter the report below this line. ---

Lightdm does not start Xsession with a user that have empty password in /etc/passwd

Tested also with the option "nullok" in

# /etc/pam.d/common-account - authorization settings common to all services
account required pam_permit.so nullok

# /etc/pam.d/common-auth - authentication settings common to all services
auth required pam_permit.so nullok

# /etc/pam.d/common-password
password required pam_permit.so nullok

# /etc/pam.d/common-session
session required pam_permit.so nullok

As described here: http://wiki.debianforum.de/Accounts_ohne_Passwort_einrichten

There is message in auth.log:
Apr  5 22:52:54 dell-d620 lightdm: pam_unix(lightdm:auth): authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=  user=gast

Tested also with gdm3. It asks for "pam_mount password:" and upon pressing "login" button starts Xsession without any password.
