The default ImpersonationMode is ImpersonateCurrentUser for DM OPENQUERY (расширения интеллектуального анализа данных) and out of line data sources, and the default for processing and server synchronizing is ImpersonateServiceAccount.

|
| ImpersonateServiceAccount | The credentials of the service account are used.
Примечание
Only Server Administrators can designate a data source impersonation mode as ImpersonateServiceAccount
|
|
| ImpersonateAnonymous | Currently not supported. | |
| ImpersonateCurrentUser | The current user is impersonated.
Примечание
This is valid for OPENQUERY (расширения интеллектуального анализа данных) statements only
|
|
| ImpersonateAccount | This option is used when the service uses the account and (optionally) a password associated with the data source.
Примечание
The absence of a password indicates that the service account will request a Kerberos ticket for the data source service and the domain will check to see if service account can delegate credentials to the data source.

Each data source object has an ImpersonationMode which states how the service authenticates itself to the data source.
