External User Sources in VMware Aria Operations

You can obtain user accounts from external sources so that you can use them in your VMware Aria Operations instance.

There are two types of external user identity sources:

• Lightweight Directory Access Protocol (LDAP): Use the LDAP source if you want to use the Active Directory or LDAP servers as authentication sources. The LDAP source does not support multi-domains even when there is a two-way trust between Domain A and Domain B.
• Single Sign-On (SSO): Use a single sign-on source to perform single sign-on with any application that supports vCenter single sign-on, including VMware Aria Operations. For example, you can install a standalone vCenter Platform Services Controller (PSC) and use it to communicate with an Active Directory server. Use a PSC if the Active Directory has a setup that is too complex for the simple LDAP source in VMware Aria Operations, or if the LDAP source is experiencing slow performance.
