I applied the patch, and retried the NTLM in LDAP authentication.

When I compare the NTLM hash provided by the dovecotpw utility to the one I have in my SAMBA ldap, it appears to be exactly the same.
When I use the LDAP passdb backend, I can see in the log file that dovecot has received the correct NTLM hash value, but outlook fails to authenticate successfully.
I'm using the debianized dovecot version v1.0.beta2.
It shouldn't matter if it's in LDAP or in passwd-file. I'd guess it reads the scheme wrong. The passwords in LDAP probably aren't prefixed with {NTLM}? Have you set default_pass_scheme = NTLM in dovecot-ldap.conf?
Have you tried if plaintext logins work with NTLM hashes in LDAP? If they don't, try setting auth_debug=yes and auth_debug_passwords=yes and check if the logs help.
I've tried putting plaintext passwords in LDAP, and this time it works. Putting the NTLM hash in LDAP still fails, but the value in LDAP is exactly the same as the value generated by dovecotpw.
What should I try next?
Could you try -beta3 with attached patch applied ?
