I found tons of articles how to enable password complexity, can someone guide me to how to disable it? (oracle linux)

This is my system-auth

# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth        required
auth        sufficient nullok try_first_pass
auth        requisite uid >= 500 quiet
auth        required

account     required
account     sufficient uid < 500 quiet
account     required

password    requisite try_first_pass retry=3
#password    requisite min=N0,disabled,12,8,7 retry=3
password    sufficient md5 shadow nullok try_first_pass use_authtok
password    required
#password    [success=1 default=ignore] minlen=1 sha512

session     optional revoke
session     required
session     [success=1 default=ignore] service in crond quiet use_uid
session     required

commenting out or changing the arguments, just break pam and make it impossible to use passwd at all. Thanks

How about trying to uncomment the "#password [success=1 default=ignore] minlen=1 sha512" part and see if that works? – i.h4d35 Dec 13 '12 at 15:11

PAM module pam_cracklib is responsible for testing password for complexity. configure like below.

#password    requisite try_first_pass retry=3 type=
password    sufficient sha512 shadow nullok 
password    sufficient use_authtok
password    required
