Ok, running the following locally also triggers it with nt4_member in
some cases.
Also adding
diff --git a/nsswitch/wbinfo.c b/nsswitch/wbinfo.c
index 80b245a..9b0e89f 100644
--- a/nsswitch/wbinfo.c

@@ -2094,6 +2094,7 @@ static bool print_domain_users(const char *domain)

Gives me

It seems to be this check in wbcCtxListUsers()
if (num_users != response.data.num_entries) {
wbc_status = WBC_ERR_INVALID_RESPONSE;
printf("%s:%s: %s %u != %u\n", __location__, __func__,
wbcErrorString(wbc_status),
(unsigned)num_users,
(unsigned)response.data.num_entries);
goto done;
}
I got 1 != 5.
