Access from .NET with NCO 3.0 to SAP Systems with SNC (Win Domain SSO) don't work

Question

0.00/5 (No votes)

See more:

I changed the .Net Connector in my programm from 2.0 to 3.0. All work very fine, but the connection to Systems with Secure Network Connection SNC to access with the Windows Domain Account don't work.

May be I misunderstood the saplogon.ini, with this and the NCO 2.0 it works. Is there any software preparation required or is there something missing in my RfcConfigParameters:

p[RfcConfigParameters.AppServerHost] = "r3-pq1";
p[RfcConfigParameters.SystemNumber] = "1";
p[RfcConfigParameters.SncMode] = "1";
p[RfcConfigParameters.SncPartnerName] = "p:<domain>\\<user>";
p[RfcConfigParameters.SncLibraryPath] = "C:\\Windows\\system32\\sncgss32.dll";

Please help

You may wish to read this[^] if you haven't seen it yet. It outlines some of the changes from version 2 to 3. The security model was redesigned to you may be affected by some of those changes. Included in your 3.0 downloads you should find some documentation outlining the differences between the versions. You may have to refactor some code to make it work. I personally don't use these systems, but I found answers with a handful of google searches.
Cheers.

Hi Marcus, thank you for your reply but sorry that didn't helped. The link explains only the basics and the basics works. In the Internet I find a lot of experts who use the NCO3 but no one with SNC. Is there really no one who has an idea? I am only a poor Windows programmer with a less knowledge of SAP.

In the meantime I got an reply at the SAP forum which helped me to find the answer: I didn't use the client number. If you don't use the client number the NCO 2.0 log in at the default client (in our case "800"). The NCO 3.0 log in at client "000".
