MS SQL Linked Server to HANA 2.0 - error 10 authentication failed

I have some trouble setting up a linked server to a SAP HANA database. On the SQL-Server machine (SQL-Server 2019) i installed the ODBC drivers and set up a 64 System DSN. When I click on the "Test Connection" it succeeds. Driver version is 2.04.167.62361 I then Setup the Linked server as Follows: EXEC sp_addlinkedserver @server='SAP', @srvproduct='HANA', @provider='MSDASQL', @datasrc='HANA64'; --> Name of the ODBC DSN EXEC sp_addlinkedsrvlogin @useself = 'FALSE', @rmtsrvname = 'SAP', @locallogin = NULL, @rmtuser = 'Readonly', @rmtpassword = 'my_pwd'; It creates the Linked Server. When I test the connection in SSMS I get: > [SAP AG][LIBODBCHDB DLL][HDBODBC] General error;10 authentication > failed All research on the internet did not get me further. Any Ideas? My ODBC DSN Connection looks like follows:
