NSX Manager instances on each site are configured to integrate with the VMware vCenter Single Sign-On™ service associated with the vCenter Server resource to which they are bound. This facilitates the secure authentication of vCenter Server users within NSX for vSphere and also any of the identity stores configured under vCenter Server, including LDAP, Active Directory, and NIS directories. The integration is set through the NSX Manager user interface by supplying the address and port of the vCenter Single Sign-On server.

The NTP settings for the NSX Manager are configured so that it is in sync with the time of the vCenter Single Sign-On service. Authentication using this method is highly time-sensitive, so verify that the components involved are not subject to drift.
