KDE and PAM

[Andrea Venturoli]

Hello.
I've got a problem.
I'm using KDE 3.4.3 on a 5.4p8 system: simply it does not check for 
password!!!
At login (using kdm) I just enter my username and can leave the password 
field blank or type whatever I want. The same happens after the screen 
saver has locked up my session.
Here's my /etc/pam.d/kde:

#
# $FreeBSD: src/etc/pam.d/kde,v 1.6 2003/04/30 21:57:54 markm Exp $
#
# PAM configuration for the "kde" service
#

# auth
auth            required        pam_nologin.so          no_warn
#auth           sufficient      pam_krb5.so             no_warn 
try_first_pass
#auth           sufficient      pam_ssh.so              no_warn 
try_first_pass
#auth           required        pam_unix.so             no_warn 
try_first_pass
auth            sufficient      /usr/local/lib/pam_smb_auth.so

# account
#account        required        pam_krb5.so
account         required        pam_unix.so

# session
#session        optional        pam_ssh.so
session         required        pam_permit.so




I've tryed googling, but I only came up either with vulnerability 
reports for older KDE releases (which should have been corrected) or 
with hints which are specific to some particular Linux-based OS.
Any hiny appreciated.

BTW, I'm also using nss_ldap, in case it matters, and text console login 
works fine.

  bye & Thanks
