[TYPO3-english] ig_ldap_sso_auth issue

[Hebus.JD]

Hi again!

I'm having a new issue :

When activating BE LDAP Auth, with the settings from xavier's tutorial, 
I have a PHP error :
PHP Fatal error:  Call to a member function includeTCA() on a non-object 
in 
C:\TYPO3_4.3.7\htdocs\Dummy\typo3conf\ext\ig_ldap_sso_auth\lib\class.tx_igldapssoauth_auth.php 
on line 131

The error doesn't occur if I comment the line 131 : 
$GLOBALS['TSFE']->includeTCA();

Since I don't know what it does, I'm not sure how about I should feel 
about it.
Any Ideas?
