Refer to the Exhibit. An administrator is adding an Active Directory over LDAP Identity Source for vCenter Single Sign-On, as indicated in the Exhibit. What is the correct value to configure for the D

The Domain alias in vCenter SSO is specifically the NetBIOS name of the Active Directory domain - for example, 'CORP' for the FQDN 'corp.example.com'. This short name enables users to authenticate using the DOMAIN\username format. It must match the actual NetBIOS name registered in Active Directory Domains and Trusts to function correctly.

The fully qualified domain name is entered in the Domain name field, not the Domain alias field; the alias is reserved for the shorter NetBIOS name.

vsphere.local is the built-in vCenter SSO local domain and has no relationship to the external Active Directory domain alias being configured.

The Domain alias must match the domain's actual registered NetBIOS name; it is not a free-form user-defined label and an arbitrary value will cause authentication failures.
