Audit Database Mirroring Login Event Class Data Columns

Data column Type Description Column number Filterable
ApplicationName nvarchar Unused in this event class. 10 Yes
ClientProcessID int Unused in this event class. 9 Yes
DatabaseID int SQL Server Profiler displays the name of the database if the ServerName data column is captured in the trace and the server is available. Determine the value for a database by using the DB_ID function. 3 Yes
EventClass int The type of event class captured. Always 154 for Audit Database Mirroring Login. 27 No

EventSubClass int The type of event subclass, providing further information about each event class. The table below lists the event subclass values for this event. 21 Yes
FileName nvarchar Supported authentication method configured on the remote database mirroring endpoint. When more than one method is available, the accepting (target) endpoint determines which method is tried first. Possible values are:



None. No authentication method is configured.

NTLM. Requires NTLM authentication.

KERBEROS. Requires Kerberos authentication.

NEGOTIATE. Windows negotiates the authentication method.

CERTIFICATE. Requires the certificate configured for the endpoint, which is stored in the master database.

NTLM, CERTIFICATE. Accepts NTLM or the endpoint certificate for authentication.

KERBEROS, CERTIFICATE. Accepts Kerberos or the endpoint certificate for authentication.

NEGOTIATE, CERTIFICATE. Windows negotiates the authentication method, or an endpoint certificate can be used for authentication.

CERTIFICATE, NTLM. Accepts an endpoint certificate or NTLM for authentication.

CERTIFICATE, KERBEROS. Accepts an endpoint certificate or Kerberos for authentication.

CERTIFICATE, NEGOTIATE. Accepts an endpoint certificate for authentication or Windows negotiates the authentication method.

None. No authentication method is configured.

NTLM. Requires NTLM authentication.

KERBEROS. Requires Kerberos authentication.

NEGOTIATE. Windows negotiates the authentication method.

CERTIFICATE. Requires the certificate configured for the endpoint, which is stored in the master database.

NTLM, CERTIFICATE. Accepts NTLM or the endpoint certificate for authentication.

KERBEROS, CERTIFICATE. Accepts Kerberos or the endpoint certificate for authentication.

NEGOTIATE, CERTIFICATE. Windows negotiates the authentication method or an endpoint certificate can be used for authentication.

CERTIFICATE, NTLM. Accepts an endpoint certificate or NTLM for authentication.

CERTIFICATE, KERBEROS. Accepts an endpoint certificate or Kerberos for authentication.

RoleName nvarchar The role of the connection. This is either initiator or target. 38 No
ServerName nvarchar The name of the instance of SQL Server being traced. 26 No
SPID int The server process ID assigned by SQL Server to the process associated with the client. 12 Yes
StartTime datetime The time at which the event started, when available. 14 Yes

TargetUserName nvarchar Login state. One of:

INITIAL

WAIT LOGIN NEGOTIATE

ONE ISC

ONE ASC

TWO ISC

TWO ASC

WAIT ISC Confirm

WAIT ASC Confirm

WAIT REJECT

WAIT PRE-MASTER SECRET

The table below lists the subclass values for this event class.

ID Subclass Description
1 Login Success A Login Success event reports that the adjacent database mirroring login process has finished successfully.
2 Login Protocol Error A Login Protocol Error event reports that the database mirroring login receives a message that is well-formed but not valid for the current state of the login process. The message may have been lost or sent out-of-sequence.
3 Message Format Error A Message Format Error event reports that the database mirroring login received a message that does not match the expected format. The message may have been corrupted, or a program other than SQL Server may be sending messages to the port that database mirroring uses.
4 Negotiate Failure A Negotiate Failure event reports that the local database mirroring endpoint and the remote database mirroring endpoint support mutually exclusive levels of authentication.
5 Authentication Failure An Authentication Failure event reports that a database mirroring endpoint cannot perform authentication for the connection due to an error. For Windows Authentication, this event reports that the database mirroring endpoint is unable to use Windows Authentication. For certificate-based authentication, this event reports that the database mirroring endpoint is unable to access the certificate.
6 Authorization Failure An Authorization Failure event reports that a database mirroring endpoint denied authorization for the connection. For Windows Authentication, this event reports that the security identifier for the connection does not match a database user. For certificate-based authentication, this event reports that the public key delivered in the message does not correspond to a certificate in the master database.
