ESXI-06-000032 - The system must prohibit the reuse of passwords within five iterations.

Information

If a user, or root, used the same password continuously or was allowed to change it back shortly after being forced to change it to something else, it would provide a potential intruder with the opportunity to keep guessing at one user's password until it was guessed correctly.

Solution

To set the remember option, add or correct the following line in '/etc/pam.d/passwd':

password sufficient /lib/security/$ISA/pam_unix.so use_authtok nullok shadow sha512 remember=5
