Try removing this line, if I'm not mistaken it's according to openssl
syntax while openldap is (usually) compiled against gnu-tls which uses
a different syntax.
Also SSLv2 is generally not considered secure so unless you have some
apps that cant do SSLv3 or better (TLSv1 == SSLv3.1) you should turn
SSLv2 of.

Are your certs self-signed or from a CA?
Did you make sure that the private key cert (and the other certs too?)
are not stored encrypted (-nodes switch in openssl).

You may want to change your password since you have posted the hash
(and also your domain) it is now possible to start brute forcing (or
use rainbow tables) the hash and since the domain where this hash was
used is known (and at least the LDAP username) that is a big security
leak.

Other than that version info  and debug info (as Dan asks) is always
good to provide when you have a question.
