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

There are two types of external user identity sources:

Lightweight Directory Access Protocol (LDAP)

Use the LDAP source if you want to use Active Directory or LDAP servers as authentication sources. Note that 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 vRealize Operations Manager. For example, install a standalone vCenter Platform Services Controller (PSC) and use it to communicate with an Active Directory server. This is useful when the Active Directory has a complex setup, and the simple LDAP source in vRealize Operations Manager cannot handle the set up, or is experiencing slow performance issues. In addition, if the PSC is configured to use Active Directory with integrated Windows authentication mode, SSO users can log in using Windows authentication.
