package: libpam-modules
Version: 1.1.3-7.1
Severity: serious

A library in /lib shouldn't depend on a library in /usr/lib. However, pam_userdb.so has such an issue.

root@zoot:~# ldd /lib/x86_64-linux-gnu/security/pam_userdb.so
        linux-vdso.so.1 (0x00007ffff6081000)
libpam.so.0 => /lib/x86_64-linux-gnu/libpam.so.0 (0x00007f22218a3000) libdb-5.1.so => /usr/lib/x86_64-linux-gnu/libdb-5.1.so (0x00007f2221520000) libcrypt.so.1 => /lib/x86_64-linux-gnu/libcrypt.so.1 (0x00007f22212e8000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f2220f3f000)

This problem also seems to still be around in version 1.1.8-3.1, which is in jessie.

At this point, moving libraries from /usr to /lib appears to be
counterproductive and we shouldn't do that anymore.
Thus closing the bug report.
