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!)?

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. Lennart -- Lennart Poettering, Berlin
