Using ldap module to return variables to use in other modules.

Hi all,
At the moment, I'm trying to get FreeRADIUS (Version 2.1.12 on CentOS 6.5, 64-bit) to do something a little oddball. I've got users in an Active Directory 2008 R2 domain, and I need to be able to authenticate them via RADIUS. However, it's complicated a little because I want to use UserPrincipalName. The longterm aim for this is a server doing EAP with inner and outer tunnels for Eduroam, hence the UPN. NTLMauth won't work with UPN natively - it usually just strips the realm off and uses the username portion. This won't work for me because the UPN and sAMAccountNames don't match (legacy reasons) and also will never match as we'll be using the full UPN matching the user's email address in future for other stuff, and having different UPNs to Emails will cause confusion as they'll be too similar.
I've been told it may be possible in the authorise section to query LDAP using the UPN, and return the sAMAccountName into a variable, then use that in the Authenticate section to actually auth the user via NTLMauth.
I've managed to modify the dictionary and ldap.attrs files, so when I run an authentication I see in the debug my variable get something put into it (and indeed, what I expect to see in it). However, when I feed this to the ntlm_auth module, it all falls over and says the variable doesn't exist, or can't be expanded.
I followed this howto for the ntlm_auth:
http://deployingradius.com/documents/configuration/active_directory.html
I modified the ntlm module as follows:
exec ntlm_auth {
wait = yes
program = "/path/to/ntlm_auth --request-nt-key --domain=MYDOMAIN --username=%{Bucks-samAccountName} --password=%{User-Password}"
}
ldap.attrmap has an extra line (tried as both a check-item and a replyitem. I'm thinking it should be check-item as a replyitem is sent in the RADIUS reply, which I don't want).
checkItem Bucks-samAccountName sAMAccountName
And I modified the dictionary:
ATTRIBUTE Bucks-samAccountName 3003 string
Does anybody know where I'm going wrong with this? Is it even possible? I've been playing with it for a while, and getting nowhere. Unforuntately the documentation hints at only certain variables being passed into modules, but doesn't elaborate on which ones, hence resorting to the mailing list.
My complete debug follows my sig, suitably sanitised.
Thanks in advance.
