Disable passwd history feature with remember=0
- by user1915177
PAM version - pam-0.79
Is setting 0 allowed on "remember" option in /etc/pam.d/common-passwd file of pam.d module to disable passwd history feature?
With "remember=0" in /etc/pam.d/common-passwd file, I am observing a memfault when running the passwd command as a USER.
When browsed the source, the function in _set_ctrl in support.c file of pam_unix module handles wrong values of remember, but currently its not robust enough to handle 0, which is a wrong value.
So the valid and only option to disable history feature, is to not include the "remember" option in /etc/pam.d/common-passwd file and not to set-up /etc/security/opasswd file?
Could see in the following link mention of setting "remember" to 0 has no effect to remember value in "/etc/security/opasswd" file.
