As far as I know, yes. I don't deal with the Microsoft side of this.

No. At present it will authenticate 'jbloggs' and 'jbloggs at domain'. We
want to have it authenticate 'jbloggs' and 'j.bloggs at domain', but
because 'jbloggs at domain' currently works, we need to cater for it but
have to do this by stripping the realm (so it becomes just 'jbloggs').
Don't ask me 'why', I gather that the DC can recognise a userid (such as
'jbloggs') and the UPN ('j.bloggs at domain'), but it cannot recognise
three formats. So we need to change 'jbloggs at domain' to just 'jbloggs'.
Trying to change 'jbloggs at domain' to 'j.bloggs at domain' may be possible,
but we would have to start doing LDAP lookups to dig out the info.
Secondly, of course, is that we would be changing the 'User-Name' sent
to the DC, so I assume EAP would break again.

If I can't get 'jbloggs at domain' stripped of the domain, then yes it
could all be useless.
