[gentoo-user] forcing Gentoo to accept simple password

[the...@sys-concept.com]

What changing one need to make to force gentoo log-in to accept simple password.
The system is not a high security risk so I have no need for a sophisticated password.

I think it has to do something with file: /etc/pam.d/system-auth

Here is an old one:
auth required pam_env.so
auth required pam_unix.so try_first_pass likeauth nullok
auth optional pam_permit.so
account required pam_unix.so
account optional pam_permit.so
password required pam_cracklib.so difok=2 minlen=8 dcredit=2 ocredit=2 retry=3
password required pam_unix.so try_first_pass use_authtok nullok sha512 shadow
password optional pam_permit.so
session required pam_limits.so
session required pam_env.so
session required pam_unix.so
session optional pam_permit.so

and a new one:

auth required pam_env.so
auth requisite pam_faillock.so preauth
auth [success=1 default=ignore] pam_unix.so nullok try_first_pass
auth [default=die] pam_faillock.so authfail
auth optional pam_permit.so
account required pam_unix.so
account required pam_faillock.so
account optional pam_permit.so
password required pam_passwdqc.so config=/etc/security/passwdqc.conf
password required pam_unix.so try_first_pass use_authtok nullok sha512 shadow
password optional pam_permit.so
session required pam_limits.so
session required pam_env.so
session required pam_unix.so
session optional pam_permit.so

Uninstall sys-auth/passwdqc... From it's manpage:

====
DESCRIPTION
The pam_passwdqc module is a simple password strength checking
module for PAM.
====

You need to remove the 'passwdqc' USE flag from sys-auth/pambase, else
it'll get pulled in again.

Thank you, that worked!
unmerging "sys-auth/passwdqc" and compile "sys-auth/pambase" without "passwdqc" solved the problem
