VCP-DCV vSphere Security Practice Question
A vSphere environment uses Active Directory for authentication. The administrator notices that users from a specific AD group cannot log in to the vCenter Server, although other AD users can. The group is added to vCenter Server with the correct permissions. What is the most likely cause?
⚠ Common exam trap
Watch out — candidates often assume that adding a group to vCenter permissions is sufficient for authentication, overlooking the prerequisite that the group's domain must first be registered as an identity source in vCenter Single Sign-On.

Correct answer & explanation
✓
The domain of the group is not configured as an identity source in vCenter Single Sign-On
The most likely cause is that the domain of the group is not configured as an identity source in vCenter Single Sign-On. Even if the group is added with correct permissions in vCenter Server, vCenter SSO must be able to authenticate users against the domain. Without the domain listed as an identity source, vCenter cannot validate the credentials of users from that group, causing authentication failures for all users in that domain.
