hilft das:

touch /etc/security/opasswd , wenn es das noch nicht gibt

#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth required /lib/security/pam_env.so
auth sufficient /lib/security/pam_unix.so likeauth nullok
auth required /lib/security/pam_tally.so onerr=fail no_magic_root
auth required /lib/security/pam_deny.so

account required /lib/security/pam_unix.so
account required /lib/security/pam_tally.so deny=5 reset no_magic_root

password required /lib/security/pam_cracklib.so retry=3 type= minlen=8
password sufficient /lib/security/pam_unix.so remember=4 use_authtok md5 shadow
password required /lib/security/pam_deny.so

session required /lib/security/pam_limits.so
session required /lib/security/pam_unix.so

es kommt aber auch noch drauf an welche Distri du verwendest, mache pam_unix.so können kein md5, da übernimmt pam_unix2.so diese funktion oder pam_pwcheck.so
