S

security context information
Information used by MSMQ to authenticate a message. This information is extracted from the certificate before the message is sent and is used by MSMQ only when it sends a message. Security context information is used primarily when a large number of messages are sent using the same certificate.

In addition, using the correct security context information is very important when impersonating a user.

For more information, see external certificate and internal certificate.

security descriptor
An opaque structure that consists of a SECURITY_DESCRIPTOR structure and its associated security information.

Security information can include security identifiers (SID), a discretionary access-control list (DACL), and a system access-control list (SACL).

For a complete description of security descriptors, see the Platform SDK.

server input queue
The Exchange server input queue is created by the MSMQ Exchange Connector when the connector starts the first time. When an MSMQ message reaches this queue, it is picked up by the MSMQ Exchange Connector, translated into an e-mail message, and sent to the Exchange Server where it is distributed to the appropriate Exchange user.

The queue's label is set by the Exchange Connector's Setup program. In addition, the Exchange Connector sets the queue's type to the MAPI type identifier shown in the following example.

MAPI type identifier:

{5EADC0D0-7182-11CF-A8FF-0020AFB8FB50}

SID
A unique value of variable length used to identify a user or group. The SID is assigned when the user logs on and becomes part of the access token for any process started by the user.

The SID contains a 48-bit identifier authority value, a revision level, and any number of subauthority values. For a complete description of SIDs, see the Platform SDK.
