Format of User Names and Passwords

User names and passwords must follow these guidelines:

• A user name cannot contain an asterisk (*), comma (,), colon (:), or a new-line or carriage-return character.

• A user name or password must be at least one character long.

• If a user name or password contains a space, the entire name or password must be enclosed in quotation marks.

• There is no limit on the length of passwords or user names, except for command shell restrictions on the maximum number of characters that can be entered on a command line.
