Q/bug: problems retrieving and examining binary LDAP attribute

I have a binary LDAP attribute which contains a certificate and which I want to retrieve from the LDAP server using the LDAP functions of PHP. The strlen() function tells me that this string which should contain the binary certificate data is 26 bytes long but the the certificate is definitely longer. If I use the ldapsearch command line tool I get the whole set of binary data. So the data is really inside the LDAP tree but how do I access binary data using PHP in this case? It seems to me that somehow the string is terminated by something (terminating 0?). Is this a bug? I am using PHP 4.0.2 within Apache. -- Heiko Nardmann (Dipl.-Ing.), h.nardmann@secunet.de, Software Development secunet Security Networks AG - Sicherheit in Netzwerken (www.secunet.de), Weidenauer Str. 223-225, D-57076 Siegen Tel. : +49 271 48950-13, Fax : +49 271 48950-50
