[Dovecot] Dovecot SSL issue on Solaris 10 x64 (64-bit)

[Jeff A. Earickson]

Patric,

I am currently running rc7 on both a production Solaris 9 system
and a test Solaris 10 6/06 system, both 64 bit sparc.  I am the
testee/victim on the S10 box, and my home directory is a mirrored
ZFS filesystem.  So for everything has been working great with imaps.
Err, but then we don't support Tbird either.

My two quick suggestions:

1) download a copy of Sunstudio 11 (Sun's compiler system) from Sun
and install it.  It is now free.  Then compile openssl with Sun's
C compiler instead of gcc.  See if that helps the loader issues.

In general I have had marginal success mixing code/libraries built
with different compilers.  But in my case, I have openssl built
with Sun cc and dovecot built with gcc (for core tracebacks).
Works great, go figure.

2) Make sure your SSL certs work.  Here's my "how to" notes,
gleaned from www.madboa.com/geek/openssl:

    1) How to test a new certificate:

    On the box with the new cert, launch openssl's mini-web browser:

    openssl s_server -cert /opt/openssl/ssl/certs/library.cert \
            -key /opt/openssl/ssl/private/library.key \
            -www

    (in this case for library)

    Then connect to this mini-web server via a web client:

    https://library.colby.edu:4433/

    and look at the results.

    2) Verify the chain of authority.

    a) Go to /opt/openssl/ssl/certs and make sure all of the hash links
    are there.  Type "/opt/openssl/bin/c_rehash" to create them.

If your cert chains aren't right, then this may be the source of your
issues.
