Hi Amit,
What is your use case. Did you want to configure SNC wiht kerberos or SPNego for ABAP or both.
Like Christian says, you are using a quite old SLL Library and it is recommand to switch to the CommonCryptoLib (CCL) for your profile parameter snc/gssapi_lib . Please configure the same library as you use for SPNego (libsapcrypto.so.The migration from SLL 1.0 to the CCL is explained in the implementation guide: http://help.sap.com/download/sapsso/secure_login_impl_guide_en.pdf chapter 4.4
To configure your keytab on the server please refer to the the SAP Note 1837595 and use the Service Account UserID@DOMAIN instead of the SPN (SAP/...).
