Re: impersonationmode?

The impersonation mode tells Anaylsis Server what credentials to use when
connecting to the database specified in the datasource object. When you
create the datasource using the Data Source Wizard, there's an
"Impersonation Information" page where you can set this information. If the
data source is used for processing (i.e. you are training mining
structures/models from that data source), you are not allowed to set the
ImpersonationMode to "Use the credentials of the current user" due to
security considerations - you must either use the service account or use a
specific username/password.

You can change the impersonation mode by opening the data source in BI Dev
Studio and selecting one of the allowed options above on the "Impersonation
Information" tab.
