[TYPO3] Debuging FE auth

[Nino Katic]

Hello,

I'm using openldap auth ext. which i need to change to suit my needs. Ext. 
is using auth class that extends standard Typo3 auth. class and when i try 
to debug it - the openldap auth class - (ie. write die("Break point");) 
nothing happens on web page after i submit login data via login form - the 
form is just redisplayed. Anybody have some advice how to see what's going 
on ? Thx.
