SYMPTOMS

When you use smart card authentication to log on to a computer that is running Microsoft Windows XP Service Pack 2 (SP2), Windows Server 2003 Service Pack 1 (SP1) or Windows Server 2003 Service Pack 2 (SP2), the logon process is successful. However, after several moments, the Lsass.exe process encounters an access violation and terminates. 

You do not experience this problem on a computer that is running Windows XP Service Pack 1 (SP1) or the release version of Windows Server 2003.

CAUSE

This problem occurs because of heap corruption that may occur in the Lsass.exe process when you log on by using a smart card.

This problem occurs if the subject field of the certificate on the smart card is in a particular order. In this scenario, if the domain component of the subject field is not in the last few attributes, Lsass.exe experiences heap corruption. Then, the process crashes. The following example subject fields illustrate this problem.

Example 1:
DC = WIDGETS
DC = MSN
CN = dalexander
CN = Users
In this example, the domain component part of the subject field is not in the last several attributes of the subject field. In this example, Lsass.exe experiences heap corruption.

Example 2:
CN = David Alexander
CN = Users
DC = corp
DC = tailspin
DC = toys
DC = com
In this example, the domain component part of the subject field is in the last several attributes of the subject field. In this example, Lsass.exe does not experience heap corruption.
