SYMPTOMS
When you configure a three-tier Web application environment that uses Kerberos authentication, you may intermittently find that client authentication fails. For example, in the following scenario, the ticket-granting ticket (TGT) may expire before the client is authenticated to the destination computer that is running Microsoft SQL Server:
- The client connects to a Microsoft Internet Information Services (IIS) Web server.
- The client forwards the TGT to the IIS server.
- The IIS server connects to a computer that is running SQL Server by using the ticket that was forwarded by the client (Kerberos delegation).
The InitializeSecurityContext function returns a SEC_E_NO_CREDENTIALS error code in the SQL application on the Web server. Additionally, the client receives the following error message:
CAUSE
This problem may occur if the AcquireCredentialsHandle function returns an incorrect expiry time for the TGT. The ptsExpiry parameter of the AcquireCredentialsHandle function does not reflect the correct lifetime of the forwarded TGT.
