Bug#663442: Malformed sonames when compiling libnss-ldap

Package: cdbs
Version: 0.4.109
Severity: important

Hi Jonas,
as part of the hardening release goal I tried to recompile libnss-ldap
with current cdbs:

Here's how the sonames are with the version currently in the archive:

jmm@pisco:~/scratch/libnss-ldap-264$ dpkg -L libnss-ldap | grep ^/lib
/lib
/lib/libnss_ldap-2.11.2.so
/lib/libnss_ldap.so.2

Here's how they look like after a rebuild with current cdbs:

jmm@pisco:~/scratch$ dpkg -L libnss-ldap | grep ^/lib
/lib
/lib/libnss_ldap-.so
/lib/libnss_ldap.so.

I don't know anything about the internals of cdbs, but this looks like
a bug in cdbs, rather than in libnss-ldap's use of cdbs?

Cheers,
Moritz

Generally I would appreciate if you verified by building against an
older release of CDBS. This package depends unversioned on CDBS so
should (in my interpretation - it is not officially defined TTBOMK)
support _any_ officially released CDBS i.e. even the one in oldstable
(until that one is no longer officially supported by Debian).

Specifically, I did a brief(!) look at the source package, saw no
obvious risk that CDBS caused this problem, but noticed that a) last
maintainer upload was in 2009, b) I believe the package is generally
discouraged and practically replaced by libnss-ldapd, and c) topmost
Makefile.am in upstream code seemingly resolve version using "gcc
-print-multi-os-directory" against _other_ libraries, a mechanism that
looks suspocious to me and that I guess is affected by recent multiarch
changes.

Perhaps package is unmaintained and should die?
