NAME

       twoftpd-auth - TwoFTPD authentication front-end

SYNOPSIS

       twoftpd-auth cvmodule twoftpd-xfer

DESCRIPTION

       twoftpd-auth  reads  a  username  and  password  from  the  network and
       authenticates  them  using   the   CVM   module   cvmodule.    If   the
       authentication  succeeds,  it  sets the environment variables UID, GID,
       HOME, and USER to the user’s UID, GID, home directory, and  login  name
       respectively,  and  then  executes twoftpd-xfer.  It also sets GROUP if
       the CVM reports a group name, and AUTHENTICATED to 1 (twoftpd-auth  and
       twoftpd-xfer  look  for  this variable to determine what startup banner
       code to use).
