Users can log in to vCenter Server only if they are in a domain that has been added as a vCenter Single Sign-On identity source. vCenter Single Sign-On administrator users can add identity sources, or change the settings for identity sources that they added.
An identity source can be an Active Directory over LDAP, a native Active Directory (Integrated Windows Authentication) domain, or an OpenLDAP directory service. See Identity Sources for vCenter Server with vCenter Single Sign-On.
Immediately after installation, the vsphere.local domain (or the domain you specified during installation) with the vCenter Single Sign-On internal users is available.
If you have updated or replaced your Active Directory SSL certificate, you must remove and re-add the identity source in vCenter Server.
Prerequisites
If you are adding an Active Directory (Integrated Windows Authentication) identity source, the vCenter Server must be in the Active Directory domain. See Add a vCenter Server to an Active Directory Domain.
Procedure
What to do next
Initially, each user is assigned the No Access role. A vCenter Server administrator must assign the user at least to the Read Only role before the user can log in. See the topic on using roles to assign privileges in the vSphere Security documentation.
