Here’s an interesting problem, wondering how many of you out there use PCD and got stuck trying to add an ESXi host?

If you use CLI and look at the tomcat logs you will see this error:

If you see this error, it’s because your root password of your ESXi machine is more than 15 characters long. Shortern the root password to 15 and under and Bob’s your uncle! I’ve googled this for days and didn’t find the solution.

Hoping this will quickly help somebody who faced the same problem.
