I can confirm this behavior on my test VM of 17.11

Curiously, during my test of adding a new patron, the "required"
labels on the Password and Confirm fields didn't appear when I first
loaded the form. They only showed up after I hit the "Save" button,
which failed to save, and presented me with the form again, this time
with the labels added.

I got around the problem by putting the word "junk" in for the
passwords, and leaving the username blank.  Then when I edited that
patron again, I found that Koha had auto-generated a user name
consisting of the first and last names of the patron concatenated with
a "." separator.

In summary, I couldn't find a way to enter blank usernames or passwords
for patrons.  I don't recall that 17.05 exhibited this behavior.

I didn't see a problem with these fields.
