When adding an Active Directory over LDAP Identity Source for vCenter Single Sign-On, the configuration of the Domain alias is essential. This step is necessary because the Domain alias serves as a way for the vCenter Single Sign-On to understand which domain within Active Directory it should be interacting with for authentication purposes.

Including a Domain alias enables vCenter to precisely map user accounts to the appropriate Active Directory domain, thus facilitating seamless user authentication and management within the vCenter environment. Without this configuration, vCenter may not correctly recognize or authenticate users from the specified Active Directory domain, leading to potential access issues.

While unified logon credentials, direct access to the Active Directory database, and vCenter policies play vital roles in managing authentication and security within the environment, they are not specifically required for the setup of the Active Directory over LDAP Identity Source in vCenter Single Sign-On. Each of those aspects serves distinct purposes but is not a prerequisite for the linkage and proper functionality of the Identity Source itself. Ensuring the Domain alias is correctly configured is crucial for successful integration.
