LXDM login without password (not autologin)

[fenderson]

Hi!
I tried to change the behaviour of lxdm to consent to some users of my system to login without providing their password.

I added this line to /etc/pam.d/lxdm

auth sufficient pam_succeed_if.so user=someuser

but now what I get is that "someuser" gets in with any password (even blank) but needs to provide one.
Am I missing something?

Same promlem with lxdm 0.4.1
Can select user, but lxdm ask password and deny access to my passwordless account.
gdm works well with it.
