We might want to print a more useful error message after receiving the Generic Error, something like "Please make sure the password meets the complexity constraints".

This is what you get if you use alternative software:
Password does not meet complexity requirements
Your password must be at least 7 characters; cannot repeat any of your previous 24 passwords; must contain capitals, numerals or punctuation; and cannot contain your account or full name; Please type a different password. Type a password which meets these requirements in both text boxes.

milestone: NEEDS_TRIAGE => SSSD 1.11 beta

We decided that this ticket would be just about adding a simple generic message that might hint that the cause of the failure is the server password policies. The actual fix will be done later in the scope of #1837.
