APPLIES TO
- Microsoft Windows 2000 Server
- Microsoft Windows 2000 Advanced Server
SYMPTOMS
Linux client computers that use the Simple Authentication and Security Layer (SASL) protocol may not be able to make Lightweight Directory Access Protocol (LDAP) connections to a computer that is running Microsoft Windows 2000 Server and the Active Directory directory service.
CAUSE
This problem may occur if the following conditions are true:
- You use a centrally managed, single sign-on Linux environment.
- You use Active Directory as the authentication and directory service.
- The Linux client computers use SASL to connect to the Windows 2000-based server.
During the authentication protocol exchange, SASL defines or negotiates the maximum cipher-text buffer size that each side can receive. The problem occurs because the SASL implementation of Windows 2000 Active Directory does not support the maximum cipher-text buffer size that is negotiated between the client and the server. When this negotiation is unsuccessful, the Linux client software disables the connection.
For more information about SASL and the maximum receive buffer size, see the Request for Comments (RFC) 2222 document. To do this, visit the following IETF Web site:
