The SAS/ACCESS to Spark LIBNAME statement to Amazon Web Services (AWS) Databricks with OAuth 2.0 authentication (auth=oauth2) can fail with the following error message.

ERROR: No login information was available for authdomain @origin. The credentials for the user "xxxxxxxx" in the domain "xxxxxxxxx"

SAS/ACCESS to Spark supports only Personal Access Token (PAT) authentication to AWS Databricks. There is no native support for OAuth 2.0 or Single Sign-On (SSO) on AWS.

Workaround

The Simba JDBC driver for Databricks, which is shipped with the SAS^® Viya^® platform, supports the Machine-to-Machine (M2M) authorization protocol to implement the OAuth 2.0 client grant flow. You might be able to specify the required driver-level options in the "Properties" or "URL" LIBNAME option to pass the needed authentication values. For more information, see the Using OAuth 2.0 section of the Simba JDBC Driver for Databricks documentation. 

To configure OAuth 2.0 M2M-based authentication, set the following driver-level options in the SAS/ACCESS to Spark LIBNAME statement:

• AuthMech=11
• Auth_Flow=1
• OAuth2ClientId=<client ID used in specified authentication source>
• OAuth2Secret=<secret used in the specified authentication source>

For example, choose the SAS/ACCESS to Spark LIBNAME statement that corresponds to your SAS Viya platform release.
