Preparing the Central Instance
To use Single Sign-On with Client Certificates, you need to adapt the central instance profile and make sure that the necessary libraries are located in an accessible directory.
...
1. Copy the dll file for the security product that is certified for SSO with X.509 client certificates to a directory on the central instance.
2. In the instance profile of the central instance, configure the SNC parameters as shown below:
snc/enable = 1
snc/gssapi_lib = <full_path>\<filename>.dll
snc/identity/as = p:<DN name of the AS ABAP>

The
Distinguished Name part must match the Distinguished Name that you specify
when creating the SNC PSE. For more information, see
Setting SNC Profile
Parameters.
3. Stop and restart the SAP system so that the profile parameters take effect.
