Re: LDAP Write then Read On-screen Object-not-found Error When Adding Address

No, this just means that the exception thrown from getObject() is  
*not* a Horde_Exception_NotFound. The question is, why not, and what  
else is it? Add a Horde::debug($e); call below your catch line (using  
Exception instead of Horde_Exception_NotFound) and let us know the  
outcome in /tmp/horde_debug.txt.
