Specifies the level of impersonation.
Values are:

• Not
  set

  No level of impersonation is selected.

• Anonymous

  The client is anonymous to the server and the server process
  cannot obtain identification information about the client and cannot
  impersonate the client.

• Delegate

  The process can impersonate the client’s security context
  while acting on behalf of the client. The server process can also
  make outgoing calls to other servers while acting on behalf of the
  client.

• Identify

  The server can obtain the client’s identity. The
  server can impersonate the client for ACL checking but cannot access system
  objects as the client.

• Impersonate

  The server process can impersonate the client’s security
  context while acting on behalf of the client. This information is
  obtained when the connection is established, not on every call.
