Active Directory and NetBIOS Names

Although Active Directory domains are named according to DNS naming standards, a NetBIOS name must still be defined when creating Active Directory domains.

For SiteMinder to support seamless Microsoft security context, NetBIOS names should be named the same as the DNS domain name as recommended by Microsoft.

When the Active Directory domain has a DNS name that is different from its NetBIOS name, the user domain cannot be established for the web server to provide the security context when SiteMinder is configured to use an LDAP user directory.
