NAME

       nss-systemd, libnss_systemd.so.2 - Provide UNIX user and group name resolution for dynamic users and groups.

SYNOPSIS

       libnss_systemd.so.2

DESCRIPTION

       nss-systemd is a plug-in module for the GNU Name Service Switch (NSS) functionality of the GNU C Library (glibc), providing UNIX user and
       group name resolution for dynamic users and groups allocated through the DynamicUser= option in systemd unit files. See systemd.exec(5) for
       details on this option.

       This module also ensures that the root and nobody users and groups (i.e. the users/groups with the UIDs/GIDs 0 and 65534) remain resolvable
       at all times, even if they aren't listed in /etc/passwd or /etc/group, or if these files are missing.

       To activate the NSS module, add "systemd" to the lines starting with "passwd:" and "group:" in /etc/nsswitch.conf.

       It is recommended to place "systemd" after the "files" or "compat" entry of the /etc/nsswitch.conf lines so that /etc/passwd and /etc/group
       based mappings take precedence.

EXAMPLE

       Here is an example /etc/nsswitch.conf file that enables nss-systemd correctly:

           passwd:         compat mymachines systemd
           group:          compat mymachines systemd
           shadow:         compat

           hosts:          files mymachines resolve [!UNAVAIL=return] dns myhostname
           networks:       files

           protocols:      db files
           services:       db files
           ethers:         db files
           rpc:            db files

           netgroup:       nis
