[Samba] FreeRADIUS & SAMBA when Active Directory domain is not a FQDN

Hi Rowland,
Apologies for the tardy reply, I mistakenly set the mailing list to digest...
Thanks for the suggestion, I'll ask the AD guys about this but I have a feeling it is an unlikely solution as Office 365 & Skype for Business apparently relies on the UPN. Unfortunately the local domain is a result of following Microsoft's "Best Practice" in the early 2000's which has since changed.
Since I posted this I've found some suggestions around doing a LDAP lookup first and pass the results to ntlm_auth so shall do some investigation on that.

I am not a freeradius expert, but how about this, change the UPN back to
what it should be 'user at example.campus' and then add a SPN for
'user at example.com'
