No credentials were supplied Unable to establish the security context target ,SAPCRYPTO

[Former Member]

Hi Gurus,

we have .Net application that is connecting to our SAP ABAP system.we have configured SNC with SAPCRYPTOLIB library by exchanging both servers Public key certificate.

Below are the steps i have performed:

1) Installed cryptographic library in .Net application

2) Created an SNC PSE for the .Netapp server

3) created credentials for .Netapp server (as a prerequisite SECUDIR set to the location where PSE is stored) using SAPGENPSE seclogin

4) Exported the .NETapp server’s public-key certificate using the configuration tool’s command export_own_cert.

5)Imported the .NETapp Server’s public-key certificate into the application server’s SNC PSE.

6)Exported the SAP ABAP application server’s public-key certificate using STRUST.

7) Imported the SAP application server’s public-key certificate into the .NETapp Server’s SNC PSE using the configuration tool’s command maintain_pk.

Thus two servers can identify each other using SNC.

We are using below parameters to connect to SAP system from .Net

SAP hostname: /H/router_IP/S/3291/H/SAP_ABAP_IP

Client: 500

sys no: 00

Snc library path: C:/sapcryptolib/sapcrypto.dll

SNC partnername: p:CN=N74, OU=I0022934564, OU=SAP Web AS, O=SAP TrustCommunity, C=DE

while creating connection we are getting below error "ERROR GSS-API(maj): No credentials were supplied .Unable to establish the security context

target p:CN=N74, OU=I0022934564, OU=SAP Web AS, O=SAP TrustCommunity, C=DE "

for troubleshooting steps i have deleted credentials from .net aap server and recreated the credentials but still getting the same issue. Since we are using routerstring , is there anything that we need to look into from router point of veiw.

Please let me know what to look and how to troubleshoot the issue.

Thanks,

kriss
