Steve, I agree:
This error gets printed with "-1" under too many
conditions. Just look at:
libraries/libldap/tls2.c::ldap_pvt_tls_set_option()
RC Return Code -1 could happen in about a dozen places.
I think we need to take a two step approach to fixing this:
1) Long term, implement OpenSSL's err(3)
2) Short term, in servers/slapd/main.c:
Debug( LDAP_DEBUG_ANY,
"main: TLS init def ctx failed: %d\n",
rc, 0, 0 );
We should change / append to this to clarify:
if (rc < 0)
Debug( LDAP_DEBUG_ANY, "main: something has gone terribly
wrong in creation of the SSL data structure. Check
filesystem permissions, ownership bits, ACLs, configuration
file paths. Resort to strace(1)/ktrace(1)
debugging.\n",rc,0,0);
if (rc > 0)
Debug( LDAP_DEBUG_ANY, "main: something has gone wrong
in creation of the SSL socket data structure. Please
check the OpenSSL error code above against:
/usr/include/openssl/ssl until we err(3) support\n",rc,0,0);
I will submit a patch.

What are you talking about? tlso_report_error() already prints the OpenSSL
error messages. All OpenSSL error messages have been fully logged, for years.

Pointless, since all failures inside init_ctx already call tlso_report_error().

Great, however it doesn't change the fact that no meaningful error is
being reported:

Thank you. This is exactly what I was looking for. The problem in my
case is that these errors go to stdout and are not logged via syslog.
Even with full debugging turned on, you will see no such errors printed
to logs, although all the other data is. This doesn't jive well with
many systems in which the daemons are started via scripts (FreeBSD /
NetBSD rc.d, linux init.d) in which daemon output to stdout is often lost.

What are you talking about? tlso_report_error() already prints the OpenSSL
error messages. All OpenSSL error messages have been fully logged, for
years.
I think I see the issue: tlso_report_error() uses libldap's Debug(), which
does not hit syslog. We only see TLS logs with -d stats.
