  All the ftp server does is check to see if the account exists on
the machine and checks for the password.  Also, it checks the file
/usr/etc/ftpusers for the account name.  If the account name is
there it will not allow that account to be used for ftp.  If you
have src you might want to have the server check to see what is in
the login-shell portion of the /etc/passwd entry; depending upon
what is there deny or restrict access.

  An anonymous account is different than anonymous
ftp.  Ftp is set up so that if the user ftp exists and the directory
/usr/spool/ftp exists, anonymous ftp will be allowed and the
anonymous ftp user will be put in the /usr/spool/ftp directory.  An
account name "anonymous"  is probably not a good choice for a name.

ftpusers, ftp, anf ftpd.
