Package: libnss-ldapd
Version: 0.9.4-3+deb8u1
Severity: minor
Dear Maintainer,
libnss-ldapd does not appear to respect the content of debconf when asking its
question of which items to configure in nsswitch.conf.
When you perform a dpkg-reconfigure on libnss-ldapd, it will show you the list
of databases as configured in nsswitch.conf, not as recorded in debconf. It
does record the answer into debconf.
As an example, let's assume that I originally installed the package and selected
the passwd and group databases to look up using ldap. This adjusts
nsswitch.conf
and records in debconf that I'd selected passwd and group. Next, I change that
answer (using debconf-set-selections) to only choose passwd. Run
dpkg-reconfigure and it again shows both passwd and group, since that is what
nsswitch.conf is currently configured with. I was expecting this to show me
just passwd as that is what is stored in debconf.
This bug prevents me from being able to change the answer in debconf and then
cause the package to apply that configuration via running:
"dpkg-reconfigure -fnoninteractive libnss-ldapd". I would presume that this
would also prevent me from pre-answering the question before installing the
package too.

I have done some testing and the configuration seems to work as
designed as far as I can tell.

Before the debconf questions are run, the current configuration is
loaded into debconf. This is because manual changes in configuration
files should not be overwritten by debconf values. Also see
https://lintian.debian.org/tags/debconf-is-not-a-registry.html
Not loading the current configuration in debconf would break this use
case:
- user installs libnss-ldapd
- user modifies /etc/nsswitch.conf manually
- user upgrades libnss-ldapd
If the debconf answeres were used the manual changes would be lost when
upgrading the package.
This makes debconf handling pretty complicated in combination with
preseeding. For nslcd.conf this is handled by only using the preseeded
values if nslcd.conf is not yet present (i.e. on first installation).
For nsswitch.conf it only uses the preseeded value if no ldap map has
been configured in nsswitch.conf.

This should work as described above. If you find that it does not work,
please file a new bug or re-open this one.
Thanks,
