SAP DMS: SNC not working

[Former Member]

Hi Folks,

Recently SSO was configured in our environment for all SAP ABAP systems. This lead to the SAP Easy DMs not working any more. i get the following error:

Logon failed (RFC_ERROR_COMMUNICATION)!
SAP_CMINIT3 : rc=20 > Connect to SAP gateway failed
Connect_PM  GWHOST=ciec3, GWSERV=sapgw00, SYSNR=00

LOCATION    CPIC (TCP/IP) on local host with Unicode
ERROR       SncPDLInit()==SNCERR_INIT
            Unable to load GSS-API DLL
            named "C:\Program Files
            (x86)\SAP\FrontEnd\SecureLogin\lib\secgss.dll"
TIME        Tue May 29 16:09:27 201
RELEASE     710
COMPONENT   SNC (Secure Network Communication)
VERSION     5
RC          -1
MODULE      sncxxdl.c
LINE        378
DETAIL      Load

Looking at this error its quite clear that there is a problem with the secgss.dll file. I reinstalled the SSO Secure Login Client but to no avail. The strange thing is that SSO to the ABAP system works and this uses the same secgss.dll file. So if there is no problem with the dll file why does the DMS give me a problem? Any ideas here?

Thanks in advance!

Hello Atulya,

First thing you need to check the authorization from basis side.

Go through the following notes as well : 734392, 1276709 .

Also , this link : http://scn.sap.com/thread/1334393 is kind of similar to your issue.

Hope it helps

Hi Simran,

Thanks for your reply!

The problem is not with any authorization from the basis side. I have already logged into the basis system with the same username and password and there are no issues. The problem is with the Easy DMS using SNC and reading a particular library file.

As an additional information I have cloned this to a test environment and disabled SNC and this works fine. This just doesnt work with SNC activated which is what is required.

Best Regards,
