Is that digest ? or basic ?

Maybe nothing ;-) 

Asking for NTLM(Windows) authentication _isn't_ the same, at least from
a security point of view, as doing basic authentication to an LDAP
server. So I don't think we should allow this scenario to work - at
least not by default (i.e. with an identical web.config as IIS is

However, from a functional point of view, this scenario is equivalent to
the original IIS/ASP.NET application - meaning that some applications,
with lower/different security requirements, could benefit from this.

AFAIK Apache/mod_mono/mono don't share enough information to make this
scenario work (at least right now) and I don't know enough about them to
say if this would be an easy task (or not). Maybe Gonzalo can clarify
this :-)

You could also (well probably) deal with this at the application level
by either :
(a) asking Apache for the information (if possible/available); or 
(b) do the LDAP authentication yourself (e.g. with
and finally create (and assign) the Identity object.
