Please keep in mind that the example in the SAS note mentions a libname statement using MLE. That uses the library definition in the metadata but also has permissions that it takes into consideration: Read, Write, Create, Delete.
An alternative to that is to use just a libname statement using an engine such as BASE/ DB engine within an autoexec however you are then not using the metadata and hence not fully utilising the benefits of the SAS 9 architecture. My 2 cents worth on that point.
thank you for your answer! I've tried what I could, but unfortunately it didn't work...and I'm not the admin of the SAS Server, so I couldn't even try everything described.
However, I'll send this KB articles to our admin, with the hope that he's able to perform this tests.
Thanks again, I hope to be able to write soon with some better news
