strange ldap bind to a Sun DIrectory Server 5.2

Hello, One of my php script works no more after an upgrade to a 5.2 Directory Server. In fact everthing is ok but the ldap_modify function. This function returns : Warning: ldap_modify(): Modify: Insufficient access My local ldap admin has sent me the log for the transaction : [27/Sep/2005:14:23:09 +0200] conn=4413 op=0 msgId=4 - BIND dn="" method=128 version=2 The bind which is Ok (the script can reach specific attributes in the ldap_get_entries function) turns into an anonymous bind on the ldap server ! In console mode the account used for the bind performs the modification without any difficulties. I've tried the directive : ldap_set_option($ldap_connection, LDAP_OPT_PROTOCOL_VERSION, 3); but it makes no change... php-cli-4.3.10-7.2.102mdk libphp_common432-4.3.10-7.2.102mdk php-ldap-4.3.10-6mdk Any idea ? Thanks. Nicolas Guilmain Orléans France
