ExtAuth with Linux Shell Script is not Working it seems. [eJabberd 1.1.4]

I am Using eJabberd-1.1.4 on CentOS 5.x.

I want to use External Authentication using a Linux Shell Script itself.
As a trial i have the following code. If Configured the Server for external auth with the following script, The Script getting executing while the server starting up.

After that, If try to Authenticate with the server, i am not getting data to the Script. The script keep on trying to read some thing from the Standard INPUT. But nothing is available forever.

I think i am doing some thing wrong it seems.

Please Help me out.

Thanks in advance.

--- Server Config ---

% For authentication via external script use the following:
{auth_method, external}.
{extauth_program, "/home/ejabberd-1.1.4/auth/authConnector.sh"}.

% Host name:
{hosts, ["im.server.org","guest.server.org"]}.
{host_config, "im.server.org", [{auth_method, external}]}.

-- Extauth Srcipt file --

#!/bin/sh
# Init Log file located at /tmp/authConnector.log

echo `date` "--- Log ---" > /tmp/authConnector.log
echo `date` "Arguments : $*" >> /tmp/authConnector.log
echo `date` "Starting Ext Auth Loop" >> /tmp/authConnector.log

#
# User defined vars
#

# Possibles states are 1 - 'run'(default), 0 - 'stop'
state=1

while [ $state -eq 1 ]
 do
  echo `date` "Waiting for input from the eJabberd" >> /tmp/authConnector.log
  read params
  echo `date` "Params : $params" >> /tmp/authConnector.log
  # Do Authentication
  # For the time being, Just return Success
  echo "0201"
 done

#
# End of the Script
