Change passwords in Active Directory

Hi,
	I'm trying to change a user's password in AD 2003 using the C LDAP SDK,
and running into a bit of a brick wall (which I'm more than willing to
accept is simply because of my own limited knowledge :) ).

I've translated the code here into Mozilla-ese:

http://support.microsoft.com/?kbid=269190

While my test app can successfully connect to AD both anonymously and
with simple binding, and over SSL, both the "delete then re-create" and
"replace" versions of the routine are (I believe) falling foul of
security restrictions on the directory server.

I've disabled password complexity requirements in AD, so that isn't
it. :)

The errors I'm getting are "Constraint violation", and (most recently)
"DSA is unwilling to perform".  I would expect these if I didn't connect
over SSL, but I'm getting them when using SSL as well.

It's probably down to this snippet from the above link:

> In order to modify this attribute, the client must have a 128-bit
> Secure Socket Layer (SSL) connection to the server. For this
> connection to be possible, the server must possess a server
> certificate for a 128-bit RSA connection, the client must trust the
> certificate authority (CA) that generated the server certificate, and
> both client and server must be capable of 128-bit encryption.

How can I ensure that this is the case?  Any other ideas?

Regards
