The permissions field of that table entry determines whether the login will be accepted or refused\&. .PP Chaque ligne de la table de contr\(^ole des connexions (\(Fo\ \&login access control table\ \&\(Fc) est compos\('ee de trois champs s\('epar\('es par le caract\(`ere \(Fo\ \&:\ \&\(Fc\ \&: .PP \fIpermission\fR:\fIusers\fR:\fIorigins\fR .PP The first field should be a "\fI+\fR" (access granted) or "\fI\-\fR" (access denied) character\&. The second field should be a list of one or more login names, group names, or \fIALL\fR (always matches)\&. The third field should be a list of one or more tty names (for non\-networked logins), host names, domain names (begin with "\&."), host addresses, internet network numbers (end with "\&."), \fIALL\fR (always matches) or \fILOCAL\fR (matches any string that does not contain a "\&." character)\&.
