ext_emconf.php is existing. I used kickstarter to create this extension 
but kickstarter generate no ext_localconf.php. This file I create by my own.

Here the structure of the whole directory:

/doc/wizard_form.dat
/doc/wizard_form.html
ChangeLog
class.tx_xxx_ad_sync_hooks.php
ext_emconf.php
ext_icon.gif
ext_localconf.php
README.txt

And here the content of ext_emconf.php:

$EM_CONF[$_EXTKEY] = array(
	'title' => 'XXX Active Directory Sync',
	'description' => 'XXX Active Directory Extension to write back some 
personal data from FE-Users to the Active Directory',
	'category' => 'be',
	'author' => 'Sascha Hierold',
	'author_email' => 'Sascha.Hierold at xxx-xxxxxxxxxx.de',
	'shy' => '',
	'dependencies' => '',

I think it should be updated in the documentation on 
http://typo3.org/development/articles/how-to-use-existing-hooks/page/3/. 
There the [] is described.

With "use [$_EXTKEY]" you mean I define the hook by the following?

$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauth.php']['postUserLookUp'][$_xxx_ad_sync] 
= 
'EXT:xxx_ad_sync/class.tx_xxx_ad_sync_hooks.php:tx_xxx_ad_sync_hooks->syncAD';

In which cases ext_localconf is loaded twice, it sounds like a error for me.

Thats the reason, after clearing the cache it looks like the hook is 
working and die at the position I set the PHP die; command.

Thanks for your help...
