Re: missing user authentication events.

Hi, I have the same problem Robert Harris talking about.

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)
> strings /lib/libpam.so.0 | grep audit_open
audit_open
audit_open() failed: %m

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?
