[midPoint] Cannot establish connection to SAP

Thu Jan 26 16:10:26 CET 2017

Hi Gustav,

Thanks for your reply! We've been researching the threats you mention and
also we try decompiling the JCO in order to understand how it's done and we
found that if the System ID is not specified, then the JCO requires the
ASHOST parameter to establish the connection, but if it's specified, then
the expected parameter is MSHOST.

If we set the System ID on the resource configuration parameters, we get
the "Parameter message server host ('mshost') is missing" because the SAP
Connector is hardcoded to set the ASHOST parameter always, but if keep the
System ID field empty, we get the following error from the log:

2017-01-26 10:48:01,303 [] [http-nio-8080-exec-4] ERROR

When we check the SAP connector logic, the ADMINDATA field is not set, it's
a read only attribute and seems that is not returned from SAP across the
connection process.
As we are using a SAP ABAP Netweaver 7.01, do you know if there could be
any restriction or limitation on our SAP environment? Perhaps the SAP
Connector only works for Java Netweaver instances, for example.

Many thanks!
