I have got the "fabulous" idea to create some logins using ":", and pam refuses them, even before to pass them to the corresponding authentication module. I need a kind of escape character (non alphanumeric) in the login, for and application who uses pam. So I would like to know: what is the valid character set for login ? I don't find anything specifying it. -- __o _ \<_ (_)/(_) Saludos de Julián EA4ACL -.-
