Disable password complexity in ESXi 6.5
After ESXi 6.5 setup is complete, password complexity requirements are enforced for users, esp. root. To change root password to a simple non-complex password by disabling password complexity requirements temporarily use following steps:
- SSH to host
- vi /etc/pam.d/passwd
- Comment first (requisite) and second (sufficient) lines
- Copy sufficient line nad remove auth_ok. Leave this edited line uncommented
- Save and exit vim
- Change password using passwd command to desired simple (non-complex) password
- Again vi /etc/pam.d/passwd and make it same as before
