This is not exactly what you want, but did you consider changing the uid used in the container?

Greetings,
we run some podman containers that come with their own local users, such as this one:
ironic-inspector:x:42461:42461::/var/lib/ironic-inspector:/usr/sbin/nologin

when running a top on the server, top tries to resolve the user name for that id and fails, however there is still a BE_REQ_USER request sent:
(2022-12-30 22:42:33): [be[MY.DOMAIN.NET]] [dp_get_account_info_send] (0x0200): Got request for [0x1][BE_REQ_USER][idnumber=42461]

I would hope to get rid of these requests against the domain.
unfortunately in MY.DOMAIN.NET there are uids below and above this number, so I cannot rely on the "min_id" parameter to filter users.
I would like to know if it is possible to support using user ids in the [nss] filter_users to prevent those user requests to the domain, or if anyone has any other suggestion.

I increased the entry_negative_timeout to reduce the number of queries, but filtering them out entirely would be even better.
Thank you!
