Good idea now that we have a bit more coverage in the authentication
tests.

This would attach to the regex the last character of the system user.
I would perhaps have used more characters than that (-3?), as substr()
with a negative number larger than the string given in input would
give the entire string.  That's a nit, though.

This matches only an empty string, my brain gets that right?
