Hello @sandeep_reddy,
I would recommend you a review of the documentation about Authentication Domains http://support.sas.com/documentation/cdl/en/mcsecug/64770/HTML/default/viewer.htm#aboutum.htm#p18zm6... and the "SAS Intelligence Platform: Security Administration Guide".
You will need that, the user that is executing the SAS process, would be registered in the SAS metadata with the right permissions and group memberships to access the Authentication Domain you selected. Plus, the process might need to know on what server/configuration level neecs to connect, in case you have more than 1 configuration level in your server running SAS.
So, additionally to ensure that your OS user (batch user) is registered in your SAS Metadata (with the right permissions and group memberships), to ensure the implicit metadata connection and authentication, you can always add to your code the explicit connection to your metadata in your SAS code:
options metaserver="yourserver.com"
metaport=8561
metauser="your_metadata_user"
metapass="your_metadata_user_password"
metaprotocol=Bridge
metarepository=Foundation;
Again, the user will need to be registered in the metadata and with the right group membership. In this case, you could use a internal SAS account or an external OS account.
I hope this helps!
Best regards,
Juan
