But UPN is written 'domainful', eg 'username at ad.domain.name':

	root at vdcsv1:~# ldbsearch -H /var/lib/samba/private/sam.ldb -b "DC=ad,DC=fvg,DC=lnf,DC=it" "sAMAccountName=gaio" userPrincipalName | grep ^userPrincipalName:
	userPrincipalName: gaio at ad.fvg.lnf.it

but because is domainful, can be a generic (rather obviously, unique)
email?
