[Fedora-directory-users] LD_LIBRARY_PATH question

[Philip Kime]

I've just build an LDAP dev server, the same as my prod servers.
However, I can't start the console via HTTPS under X (no problems under
windows). I have the same libraries etc. on my dev box (copied from
PROD, where it works, in fact). I get the "libnss3.s0 not found". This
library is certainly in /opt/fedora-ds/shared/lib, where LD_LIBRARY_PATH
points to in startconsole. I found out why it works on PROD but not on
DEV - this is because /usr/lib/libnss3.s0 exists on PROD but not on DEV.
HOWEVER - why is it looking in /usr/lib when LD_LIBRARY_PATH is set to
look in /opt/fedora-ds/shared/lib? Here is the output on PROD, where it
works:
 
[root at hqldap01 ~]# echo $LD_LIBRARY_PATH
/opt/fedora-ds/shared/lib
[root at hqldap01 ~]# ldd /opt/fedora-ds/lib/libjss3.so
        linux-gate.so.1 =>  (0xffffe000)
        libnss3.so => /usr/lib/libnss3.so (0xf7f48000)
        libsmime3.so => /usr/lib/libsmime3.so (0xf7f28000)
        libssl3.so => /usr/lib/libssl3.so (0xf7f08000)
        libplc4.so => /usr/lib/libplc4.so (0xf7f04000)
        libplds4.so => /usr/lib/libplds4.so (0xf7f01000)
        libnspr4.so => /usr/lib/libnspr4.so (0xf7ed0000)
        libjvm.so => not found
        libjava.so => not found
        libc.so.6 => /lib/tls/libc.so.6 (0xf7da5000)
        libsoftokn3.so => /usr/lib/libsoftokn3.so (0xf7d3f000)
        libpthread.so.0 => /lib/tls/libpthread.so.0 (0xf7d2d000)
        libdl.so.2 => /lib/libdl.so.2 (0xf7d28000)
        /lib/ld-linux.so.2 (0x56555000)

This upsets me as I assumed that it was using the nice new libnss3 etc.
libs from the fedora tree. LD_LIBRARY_PATH seems to be doing nothing at
all. I can't see any SUID/SGID things in there which would disable
LD_LIBRARY_PATH? On DEV, it doesn't work because:
 
[root at ldapdev001 ~]# echo $LD_LIBRARY_PATH
/opt/fedora-ds/shared/lib
[root at ldapdev001 ~]# ldd /opt/fedora-ds/lib/libjss3.so
        linux-gate.so.1 =>  (0xffffe000)
        libnss3.so => not found
        libsmime3.so => not found
        libssl3.so => not found
        libplc4.so => not found
        libplds4.so => not found
        libnspr4.so => not found
        libjvm.so => not found
        libjava.so => not found
        libc.so.6 => /lib/tls/libc.so.6 (0xf7e4a000)
        /lib/ld-linux.so.2 (0x56555000)

 
Now I'm worried that by PROD servers are using older libraries by
finding them in /usr/lib ...
