Firstly, Thanks for your suggestions. I went to the CPAN site but couldn't retrieve much about this module. Let me confess that I am just learning perl and don't know much about using the modules. And this script that I am trying to debug is written by someone else. I have, tried to isolate the problem. If I comment out this line "use Mozilla::LDAP::API qw(:constant :api :ssl);" then the error that it gives is : Undefined subroutine &main::ldap_init called at ./debugLogin.cgi line 288. The subroutine used here is as: 
sub openLDAPConnection ( ) {
  my ( $host, $port, $binddn, $password ) = @_;
  my ( $ld );

  # Initialize LDAP Connection
  if (($ld = ldap_init($host,$port)) == -1 ) {
    return -1;
  }

  # Bind as $binddn, $password on the LDAP connection
  if ( ldap_simple_bind_s($ld,$binddn,$password) != LDAP_SUCCESS) {
    return -1;
  }

  return $ld;
} # end of openLDAPConnection
