SYMPTOMS

Consider the following scenario:
  • You are running an Active Directory Application Mode (ADAM) instance on a Windows Server 2003-based computer.
  • You connect to the ADAM instance by using the Secure Sockets Layer (SSL) 3 protocol.
  • The certificate that you use for the SSL 3 protocol is larger than 1024 bytes.
In this scenario, the connection to the ADAM instance resets instead of being established.

Note A connection to a Windows Server 2003 domain controller of the same configuration can be established successfully.

CAUSE

This problem occurs because ADAM incorrectly handles the certificate data during the handshake process.
