SYMPTOMS

Consider the following scenario:
  1. A non-Windows Lightweight Directory Access Protocol (LDAP) client tries to bind a Windows Server 2008-based domain controller.
  2. This client uses the Simple Authentication and Security Layer (SASL) protocol for user authentication.
  3. This client makes a Secure Sockets Layer (SSL)/ Transport Layer Security (TLS) connection with the Windows Server 2008-based domain controller.
In this scenario, the Windows Server 2008 domain controller cannot negotiate Quality of Protection (QoP) for TLS connections from this non-Windows LDAP client and the binding process fails.

After this problem occurs, the following event is added into the Directory Service log:


Source: ActiveDirectory_DomainService
EventID: 1535
Category: LDAP Interface
Internal event: The LDAP server returned an error.
Additional Data
Error value:
00002029: LdapErr: DSID-0C09048A, comment: Cannot bind using sign/seal on a connection on which TLS or SSL is in effect, data 0, v1771

CAUSE

This problem occurs because Windows Server 2008-based domain controllers incorrectly deny the communication from non-Windows LDAP clients. You expereince this issue if you use Simple Authentication and Security Layer (SASL) authentication and SSL/TLS connections.

To resolve this problem, install the following hotfix on the affected Windows Server 2008 domain controllers.
