Windows versions of ntp servers cannot be used as sources in time synchronization between switches and firewalls.

Using domain controllers as ntp servers, cisco switches as clients cannot synchronize with the ntp server.

It is estimated that the reason is: ntp authenticate cannot pass

An ntp packet without authentication is 90 bytes and an ntp packet with authentication field is 110 bytes

The router is the best source of ntp, and the authentication of the client and server can match.
