In vSphere 6, if the vi-admin account get locked because of too many failed logins, and you don't have the root password of the appliance, you can reset the account(s) using these steps:
If you do have root or vi-admin access, "sudo pam_tally2 --user=mylockeduser --reset" would do it, no reboot required.
- reboot the vMA
- from GRUB, "e"dit the entry
- "a"ppend init=/bin/bash
- "b"oot
- # pam_tally2 --user=vi-admin --reset
- # passwd vi-admin # Optional. Only if you want to change the password for vi-admin.
- # exit
- reset the vMA
- log in with vi-admin
If you do have root or vi-admin access, "sudo pam_tally2 --user=mylockeduser --reset" would do it, no reboot required.
