Also, with respect to your questions about how to deal with null passwords, here's my suggestion: - if the pw_passwd field is an empty string, then don't prompt the user for a password, just return success (if a password was provided, ignore it) - if the pw_passwd field is a crypted empty string, then you can't tell that it is the empty string and you must prompt for a password or check any provided password against the crypted password (the user must be allowed to provide an empty string as their password) - there should be a way for a system/domain's administrator to specify wether users can set their passwords to no password (empty string) or empty password (emtpy string, crypted) Nico This message contains confidential information and is intended only for the individual named.
