I am attempting to connect by Azure Data Lake Analytics account with Azure Data Factory via a Linked Service. I have added the required information in the Edit linked service blade, created an app and a secret for the Service Principal ID and key, set up the API permissions, added the role assignment of Data Lake Analytics Developer to the credentials I am using, and used the Add User Wizard to give the credentials I am using the Data Lake Analytics Developer role and assign read and write permissions. When I test the connection in my linked service I get the message: "User is not authorized to data lake analytics."
These are the two tutorials I followed to create this linked service:

https://www.mssqltips.com/sqlservertip/5930/create-azure-data-lake-linked-service-using-azure-data-factory/
I cannot find any information on what I may have done incorrectly to get the error message "User is not authorized to data lake analytics."
