Centos: 6.8
I want to create a password history using PAM.
but there are some issues,
- When changing the password for root/user, the error "gkr-pam: couldn't update the 'login' keyring password: no old password was entered" is seen.
- Password change works but error is logged. (/var/log/secure)
/etc/pam.d/system-auth
Code:
#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth required pam_env.so
auth sufficient pam_unix.so nullok try_first_pass
auth requisite pam_succeed_if.so uid >= 500 quiet
auth required pam_deny.so
account required pam_unix.so
account sufficient pam_localuser.so
account sufficient pam_succeed_if.so uid < 500 quiet
account required pam_permit.so
password requisite pam_cracklib.so try_first_pass retry=3 type= dcredit=-2 ucredit=-2 lcredit=-2 ocredit=-2 minlen=8

I think adding
remember=5 in pam_unix.so is working , but old passwords not storing to /etc/security/opasswd (i was touch this file).
[root@local~]# ls -lZ /etc/security/opasswd
-rw------- root root ? /etc/security/opasswd
no old password was entered
