Issue/Introduction
When using anonymous binding for a Directory Data Service connection configured as an Authentication source, testing the Authentication source configuration or attempting to log into the Spam Quarantine returns an error message indicating that the NetBIOS name can not be resolved.
Unable to fully resolve a valid NetBIOS domain name. nCName attribute value was not found. Make sure that the bind account has read access up to and including the domain container(s), or if using Active Directory Global Catalog make sure nCName is replicated. See Administration Guide for details.
Cause
This is usually caused by the selection of an anonymous bind when the anonymous user does not have read access to the contents of the domain container in the LDAP configuration > partitions container.
Example: CN=ACME,CN=Partitions,CN=Configuration,DC=example,DC=com
Resolution
This issue may be addressed by choosing an account which has access to the Active Directory or Global Catalog CN=Partitions,CN=Configuration container. Alternately the anonymous account would need access to the following containers in the active directory:
CN=ACME,CN=Partitions,CN=Configuration,DC=example,DC=comCN=Partitions,CN=Configuration,DC=example,DC=comCN=Configuration,DC=example,DC=comDC=example,DC=com
