The lastLogon attribute is not updated when a client computer runs an LDAP simple bind operation against a Windows Server 2003-based domain controller


A client computer runs a Lightweight Directory Access Protocol (LDAP) simple bind operation against a Windows Server 2003-based domain controller. The logon process does not update the lastLogon attribute in the Active Directory directory service schema of the domain controller. However, the lastLogonTimestamp attribute is updated.


The lastLogon attribute reflects the last interactive logon, not the last network-based logon. The lastLogonTimestamp attribute reflects simple bind operations and NTLM network-based logons. This behavior enables stale account cleanup in Active Directory without affecting LDAP client authentication that uses only simple bind operations.


To resolve the problem, switch the domain to the Windows 2003 Domain Mode. Then, you can use the lastLogonTimestamp attribute.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
