Linux-PAM supports an extended configuration file syntax that allows for
such branching. The format is described in section 4.1 of the Linux-PAM
System Administrator's Guide, included in the Linux-PAM distribution.
The error code that signifies an invalid password has been typed is=20
'auth_err' (as opposed to, say, 'user_unknown').
