Re: Ambiguous SSL/TLS error messages from slapd

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.
