Today I found I could no longer log in to the VCSA vCenter appliance;
Exception in invoking authentication handler User password expired
Just because I can’t log into the web console, I could still log into the the appliance via SSH. Then invoke the shell command, and reset the root password with the passwd command;
Now if you wish, you can Disable VCSA Password Expiration: Administration > Edit > No > Save.
