Dashes in MQTT usernames - inconsistent behavior

[bogorad]

mosquitto_pass is okay with usernames like location-type-name, processes username/pass, stores in the password file. But on connection, the authentication fails.

Should either ban those in mosquitto_pass or allow authentication.

That's not the behaviour that I see. Here is a recording of me testing this out:

I suspect you are really seeing problems when using the : character, which is documented as being forbidden, but isn't rejected by mosquitto_passwd. I've changed that so it is now rejected. If you still do have a problem with the literal username location-type-name please let me know.

@ralight - I was having consistent problems with usernames containing dashes over TLS, and they went away when I disposed of dashes. Now I've done more testing, including via TLS, and it all works. Sorry for the false alarm, and thank you for responding!
