Request for external url handler when saving User account

On a system we are using single sign-on.

I was creating a new user when The POST requests kept being redirected to “index.php?action=EditView&module=Users&record=”
Which is an invalid URL I guess index was being treated as a protocol.

When navigating away from the users screen to the homepage I saw a bunch of messages regarding password complexity.

This makes no sense as passwords are not used.
Is there a way to completely Axe the password functionality from SuiteCRM?
