DBus seems to resolve user IDs directly via glibc, circumventing nscd. In more
advanced setups this leads to user's coming from LDAP or SSSD not being
resolved by the dbus system bus daemon. The effect for such users is, that all
access to the system bus (e.g. busctl or nmcli) is denied.
Adding the respective NSS modules to the service's environment solves the issue
the same way it does for nscd.
This has been reported by @qknight in his Stack Overflow question:

The correct way to override a single value would be to use something
like this:
systemd.services.nagios.serviceConfig.Restart = lib.mkForce "no";
However, this doesn't work because the check is applied for the attrsOf
type and thus the attribute values might still contain the attribute set
created by mkOverride.
The unitOption type however did already account for this, but at this
stage it's already too late.
So now the actual value is unpacked while checking the values of the
attribute set, which should allow us to override values in
serviceConfig.

* fix hwloc support (was detected by configure)
The nixos module adds a new derivation to
systemPackages to make sure that the binaries
get the generated config file. This derivation
did not contain the man pages so far.
Activating the module now makes the man pages
available in the system environment.
This change allows users to specify an alternative database method. For
example an mpd satellite setup where another mpd on the network shares
it's database with the local instance. The `dbFile` parameter must not be
configured in that case.
BIND doesn't allow the options section (or any section I'd guess) to be
defined more than once, so whenever you want to set an additional option
you're stuck using weird hacks like this:
services.bind.forwarders = lib.mkForce [ "}; empty-zones-enable no; #" ];
This basically exploits the fact that values coming from the module
options aren't escaped and thus works in a similar vain to how SQL
injection works.
Another option would be to just set configFile to a file that includes
all the options, including zones. That obviously makes the configuration
way less extensible and more awkward to use with the module system.
To make sure this change does work correctly I added a small test just
for that. The test could use some improvements, but better to have a
test rather than none at all. For a future improvement the test could be
merged with the NSD test, because both use the same zone file format.
This change has been reviewed in #40053 and after not getting any
opposition, I'm hereby adding this to master.
