SAP GUI for Java 7.20 rev 8 - SNC SSO

[Former Member]

Hi there,

I have installed SAP GUI for Java 7.20 rev 8 on my Mac OS X 10.7.4 and I am able to connect fine to my SAP systems using username and password. However, when I try to SSO to my SAP systems, I get a java dump. My Java version is: Java SE 6: 1.6.0_33-b03-424

I am wondering if the SNC section of my connection string is correct. The format I am using is:

conn=/H/sapserver.company.com/S/3200&sncname=/p/krb5:SAPService/SID@company.com&snccon=true

The error I get

Crashed Thread: 20 Java: AWT-EventQueue-1

Exception Type: EXC_BAD_ACCESS (SIGSEGV)

Exception Codes: KERN_INVALID_ADDRESS at 0x0000000600007fff

Any ideas?

Thanks in advance!

Bernard.

Hello Bernard,

you seem to use Kerberos.

If this is the case, and you are running SAP GUI for Java in 64-bit mode (latter is quite likely), try it with 32-bit mode by choosing the "Open in 32-bit mode" checkbox in the Finder info of the SAP GUI app.

See also 3.3 Release notes - Known issues in the manual part of SAP GUI for Java and search for "Mac OS X only: SNC".

Best regards

Hi Rolf-Martin,

That has got me further thanks! The error I get now is a connection failed one.

I am wondering if it is my connection string that is now causing this new issue

conn=/H/sapserver.company.com/S/3200&sncname=/p/krb5:SAPService/SID@company.com&snccon=true

Thanks,

Bernard.

I found the answer to the newest issue and it was because my principal name in my ticket viewer was the incorrect case of what was being looked for.

I deleted the entries in ticket viewer & manually added an entry with correct case e.g. Firstname.Lastname@COMPANY.COM

Hello Bernard,

I just saw your old post. I can see that you are using Kerberos (MIT Kerberos) to SSO login to SAP via SAPGUI for Java. I am trying to do the same , but since I don't know any thing about Kerberos, it is quite challenging for me.

Is it possible give some direction how I can implement this. I really appreciate it.

If you have a document, you can email it to my email at ray_vand@filemaker.com directly.

Regards,

Ray
