reuse a previously used password on photon/VMware appliances?

 


If for some reason the password had to be reset to the original, the below config file can be changed to allow re-using passwords

edit /etc/pam.d/system-password

vi /etc/pam.d/system-password

change remember=5 to remember=1 and reboot the appliance

Once the appliance boots up, set the password using

passwd root
