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).

ENVIRONMENT
