11.17 Error Messages

The following sections contains a list of common error messages.


Source: The status log or DSTrace screen.
Explanation: The driver can’t open the LDAP port on the Active Directory domain controller configured for synchronization.
Possible Cause: The server named in the driver authentication context is incorrect.
Possible Cause: You are using an IP address for the authentication context, and you have disabled non-kerberos authentication to Active Directory. kerberos requires a DNS name for the authentication context.
Possible Cause: You have incorrectly configured the driver to use an SSL connection to Active Directory.
Action: The authentication context should hold the DNS name or the IP address of the domain controller you use for synchronization. If you leave the parameter empty, the driver attempts to connect to the machine that is running the driver shim (either the same server that is running Identity Manager, or the server hosting the Remote Loader).
Action: The driver shim can authenticate only by using the pre-Windows 2000 Logon method or simple bind. If you have disabled NTLM, NTLM2, and simple bind on your network, you might receive the LDAP_SERVER_DOWN message. Enable NTLM, NTML2, and simple bind on your network.
Action: Something is wrong with the certificate that was imported to the driver shim server, or no certificate was imported. Either import a certificate, or generate a new certificate and import it.


Source: The status log or DSTrace screen.
