Authentication failed when deploy an Analysis Services project
I was trying to deploy from my computer to a server on another domain


The connection to SSAS to deploy always uses Windows Authentication, and always uses the account for Visual Studio.  To deploy to an SSAS server in another domain (or no domain), launch SSAS with 'runas /netonly' providing the target domain credentials.

This will launch Visual Studio without impersonation, but using the specified credentials for all network access.
