[TYPO3] Typo3 4.0 RC2 and LDAP (very urgent!!)

[Francesco Pessina]

Anyone have installed the LDAP extension (eu_ldap) version 2.7.7 (the 
last) on Typo3 4.0 RC2?

It install on Typo3, but when I try to import the users from AD, the 
users are showed (correctly) in the "report" of eu_ldap, but the 
extension writes only the first item of users and groups object (of the 
AD) in the Front-End Users table of Typo!!

On Typo3 4.0 beta2 it work perfectly. What is the mistake? LDAP isn't 
compatible with Typo3 RC2?

Thanks a lot for any suggestion!

Francesco.
