Quoting from passwd(4): The login (login) and role (role) fields accept a string of no more than eight bytes consisting of characters from the set of alphabetic char- acters, numeric characters, period (.), under- score (_), and hyphen (-). The first character should be alphabetic and the field should con- tain at least one lower case alphabetic charac- ter. A warning message is displayed if these restrictions are not met. I suspect SMF is being confused by you having a username that starts with a number. That isn't really allowed, though it appears to work in many cases. Try using a username that doesn't start with a number, and try using a different username that starts with a different number. I suspect you will find that if it starts with a letter then it will be just fine. -- Darren J Moffat
