Username is Spaces only

I noticed that it is possible to make a user name that is just 3 spaces. In our system we do have a number of username with spaces in them. Is there a way to restrict a SPACES only user name?

This should not be possible. Usernames are restricted to alphanumeric characters, spaces are not allowed.

How was this user created?


parameters fail when I save it - I will have to look through users for a space name. you just don’t get the grey text warning that spaces aren’t allowed if you lead with a space - is just funny - Solved
