XMPP user name / password limitation
Are there any limitations on XMPP username (JID) or password, such as maximum length, special characters allowed etc?

Tigase follows the spec: http://tools.ietf.org/html/rfc6122#section-2 whenever possible. That is if there are no other limitations (like DB storage or any other limits) Tigase allows the JID to be as described in linked specification. In summary, each JID part (domain, local part - username and resource) can be 1023 character long each. Most of UTF-8 characters are allowed which do not interfere with JID parsing. For more details, please refer to the linked specification.
