SYMPTOMS

You may not be able to bind to Lightweight Directory Access Protocol (LDAP) by using the Sun Java Naming and Directory Interface (JNDI) library against a Windows 2000-based Active Directory server.

Back to the top

Active Directory cannot handle handshake data and application data in the same packet. Depending on the timing and the underlying networking code, the final phase of the (reuse session) negotiation handshake might cause handshake data and application data to be placed in the same packet. This condition causes the bind call on the client not to work.
