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).
