Dynamics Nav 2015 Odata authentication problem

Hi,

I have a Odata connection that works perfect with Excel. Here´s the connection string:

Data Source=http://nav.impeto.local:9048/IMP-PRD-2015/OData/Company('SERVICOS')/Dimensoes;

Namespaces to Include=*;

Max Received Message Size=4398046511104;

Integrated Security=Basic;

User ID=XYZ;

Persist Security Info=false;

Base Url="http://nav.impeto.local:9048/IMP-PRD-2015/OData/Company('SERVICOS')/Dimensoes;

Password=PWY

Unfortunally, I can´t access it through Power BI desktop: it understands that it´s a oData URL, but it returns a "The user was not authorized" error, no mather what kind of authentication I use (basic / windows)

Any ideas?
