Problem with SAPDB PHP Linux ODBC

Hello,

I have a problem with PHP to connect to SAP DB via ODBC.
The System is Linux 7.3 and PHP 4.3.1 with "--with-iodbc" IODBC Support 
compiled.

The Database runs correct and i can connect via the SAP Database Manager 
and SAP Studio.
I have installed the RPM (with ODBC) sapdb-callif-7.4.3.27-1.i386.rpm.
So there is an ODBC Driver called /opt/sapdb/interfaces/odbc/lib/libsqlod.so

My ODBC.ini looks like:
[ODBC Data Sources]
CSDB1 = SAP DB

[CSDB1]
Driver          = /opt/sapdb/interfaces/odbc/lib/libsqlod.so

ServerDB    = CSDB1
ServerNode  = 192.168.1.7
Database = CSDB1
Host = 192.168.1.7



and the odbcinst.ini looks like:

[ODBC Drivers]
OpenLink (MT) = Installed

[OpenLink (MT)]
Driver = /home/openlink/lib/oplodbc.so.1
Setup  = /home/openlink/lib/oplodbc.so.1

The PHP Script calls the odbc_connect function and the following error 
appears:

Warning: SQL error: , SQL state øÛT in SQLConnect in 
/home/www/html/includes/db_class.inc.php on line 23


I dont know how to get this to work?


Thank you,

Tobias
