What is the current behavior?

We've added a check for the pw length in preparation for 2.3.
But the minimum length of the pw is only the default setting and some users might configure it in a way that shorter passwords are allowed.

What is the new behavior?

• No check in the ansible anymore. If the pw-length is shorter then the setting on the server, user will get the error from the API
