This issue occurs because permissions for group names are case sensitive in vCenter Single Sign-On (SSO) 5.5GA, but not case sensitive in vCenter Server 5.0.
When you assign permissions in vCenter Server 5.0, and you enter group names in a different case than the corresponding Active Directory group name, users in those groups can log in successfully.
In vSphere 5.5GA (Build Number 1312298), if there is a case inconsistency between the Active Directory group name and the group name in the permission, users in that group cannot log in to the inventory service with vCenter Single Sign-On.
This issue also occurs if you install vSphere 5.5GA and change a group name to a different case in Active Directory after the permission was assigned using the former group name in vCenter Server.
This issue is resolved in vSphere 5.5.0a. For more information, see the Resolution section of this article
