%Y = $hex2chr($md5(%X))
returns: …CV
Can you tell the correct valour for testuser456:jabber.org:pass456 to
compare ?

Thank you, Waqas.
I have fixed step 3, but I don't know how to compute the 16 octect in step
2. The $md5(X) always returns 32 characters. I have tried to get the first
16 and last 16 characters, but the response is wrong.
it sounds like this is returning md5hex, and not the raw characters. You
need to convert the 32 chars into 16 octects using hex2chr as shown here:
http://www.hawkee.mobi/snippet/6505/
I don't know if its a limitation of the mIRC's language and its possible to
create md5 hashes with 16 chars in others more "professional" languages, or
I'm doing something wrong.

This is incorrect. You need 16 octets, but your result is 32 octets.
Don't
hex encode in this step.
3. Create a string of the form "Y:nonce:cnonce:authzid". Call this string
A1.
%A1 = %Y $+

You are including an authzid here, Psi didn't. When there is no authzid,
you
use:
A1 = Y:nonce:cnonce
A note about authzid: You must not provide an authzid when it's the same
as
the JID you are logging in with. And when provided, it has to be a bare
JID.
See the spec:
http://xmpp.org/internet-drafts/draft-ietf-xmpp-3920bis-04.html#sasl-rules-authzid
The rest of your code is correct, and I managed to get the correct result
with the above two fixes.
