libpam.so.0 and libaudit.so.0 linking



Hi. I'm not shure wether this subscribe list is correct one to ask my question or not. If not, please suggest me where should I post it.

I have been creating an auditing procedure. I am working with 2 different OSes: CentOS 5.7 (everything is working fine) and Debian 6.0.3 (I am having problems with this).

My setup for auditd is the same in both places. However on the Debian system I get no audit events for user authentication for things like ssh and su. I do properly receive file/directory and syscall events. The problem is that libpam0g and login packages are compiled without audit functionality:

CentOS:

> ldd /lib/libpam.so.0
        linux-gate.so.1 =>  (0x00680000)
        libdl.so.2 => /lib/libdl.so.2 (0x00601000)
        libaudit.so.0 => /lib/libaudit.so.0 (0x0069a000)
        libc.so.6 => /lib/libc.so.6 (0x004a6000)
        /lib/ld-linux.so.2 (0x00482000)

Debian:

> ldd /lib/libpam.so.0
        linux-gate.so.1 =>  (0xb7733000)
        libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xb771c000)
        libcrypt.so.1 => /lib/i686/cmov/libcrypt.so.1 (0xb76ea000)
        libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb75a3000)
        /lib/ld-linux.so.2 (0xb7734000)

I managed to recompile login package but I'm having problems with compilation of libpam0g (/lib/libpam.so.0 containing package):

Any ideas what should I do? For me it looks like some packages still need to be recompiled. How can I trace it? Or maybe there is a better way to get audit events working?
