I received an email from a colleague this morning asking how to use SMO to impersonate another windows user to connect to SQL Server. Below is how this can be achieved using SMO:
Dim myServerConn As New Microsoft.SqlServer.Management.Common.ServerConnection
myServerConn.LoginSecure = True
myServerConn.ConnectAsUser = True
myServerConn.ConnectAsUserName = “username@domain”
myServerConn.ConnectAsUserPassword = “password*”
myServerConn.ServerInstance = “ServerInstance”
The one thing to be aware of is that the username needs to be in the format username@domain instead of username\domain.
