Indeed my systemd is version 245.4-4ubuntu3.15...
How could I know that the minimal required version was 249 (so I don't
bother you again!)?

Hello,
I'd like to dynamically provide group data when group data is queried by the
system (as in "getent group").
Since nsswitch can use systemd, I've looked at nss-systemd.
As a first step I tried to define a Static Drop-In JSON User Record (because
user definition is documented with more details than group definition).
So I added a toto.user in /etc/userdb/ with this
{
"userName" : "toto",
"uid" : 7777
}
and a 7777.user file pointing to toto.user
But when I run "getent passwd", there's no toto user.
I tried to see a bit what's going on with strace and I see that getent opens
libnss_systemd.so.2 and looks for files in /run/systemd/userdb.
But it's not even trying to read in the directories |etc/userdb/|,
|/run/userdb/|, |/run/host/userdb/| and |/usr/lib/userdb/|

Any suggestion?
Maybe your systemd version is simply too old? You need v249 at the
least for the above.
