Setting MTS Authentication Levels

An application’s authentication level indicates the level of security used to authenticate client requests. If authentication is not required for clients of an application, select the Anonymous option on the Security tab of the Package property sheet. If you want to require authentication of clients, use the Impersonate setting. The server process will set the authentication level to that specified level and the impersonation level to impersonate so it is not affected by distributed COM (DCOM).

Unless you have a thorough understanding of DCOM authentication levels, it is recommended that you leave your package authentication setting at the MTS default setting, which is Packet level.

The following table describes the different DCOM authentication settings:

Connect	Security checking occurs only for the initial connection.
Call	Security checking occurs on every call for the duration of the connection.

Packet Integrity	The sender's identity and signature are encrypted to ensure that packets haven't been changed during transit.
Packet Privacy	The entire packet, including the data, and the sender's identity and signature, are encrypted for maximum security.
