SSAS Gateway Connection Error

[flavioapf]

Hello,

I'm trying to add an analysis services datasource on a gateway and I keep getting an error.

A few information for context:

-Microsoft SQL Server 2014 - Developer Edition (SP1-CU4) (KB3106660) - 12.0.4436.0 (X64) 

-Also followed this article to map PowerBI user with local AD http://www.artisconsulting.com/blogs/greggalloway/2014/12/19/setting-up-a-demo-of-the-power-bi-analy...

-User is Analysis Services Admin

These are my errors:

Translated: "It's not possible to connect: I found an error trying to connect ... Details: We reached entreprise gateway mas the gateway can access local datasource"

When I run SQL Server Profiler to see what is the error, the message description is only:

Translated: "The following system error occured:" and then nothing more.

Is anything wrong from this configuration?

Thanks in advance,

Flávio Fernandes
