Several functions added to web/lib/acctfuncs.inc
try_login() to login users valid_username() checks if a new username fits criteria valid_user() checks if the user exists in the database good_passwd() only checks for minimum password length for now. can be later expanded to tell a user to make a stronger password. valid_passwd() checks if the password for the specified user is correct user_suspended() checks if the user is suspended (or not) user_delete() deletes a user Also: Enforce proper usernames on account creation Fix bug where $SUPPORTED_LANGS needs to be reset on account creation Fix bug where an account could be created with an empty passwd Display (required) beside password fields on account creation Enforce good_passwd() on account creation Signed-off-by: Loui Chang <louipc.ist@gmail.com>
