Again, all this depends on content made available through the proxy.  You
can, of course require access to any directory to be over authenticated bind
into the directory, but that requires maintaing a user id and pw for anyone
external to your company who wants to use s/mime.  This is one of the
reasons for Directory sync, it allows business partners to share directory
information.  That is why standards compliance is an issue here, and again,
active directory will require a metadirectory connector to many of the
directories already deployed.

      Would it also disclose the name of all of the

What would happen if you want to open the directory to anonymous
access to the Web ?
In such a way that you could exchange S/MIME certs with
outside people ?

Let me take the points one at a time and inline:

Do you mean that there are difficulties to access through LDAP an
Active Directory, as you want to read or use X509 certificates ?

No.  However, are you going to open your active directory to
anonymous LDAP
queries over the Internet?  If not, are you limiting S/MIME to
internal use
only?  If not then you are somewhat back to square one.

By the way,does somebody know issues about Active Directory LDAP,
or issues to read a certificate in an Active Directory ?

This worked just fine for us here, but the problem we had
with AD was that
it does not support inetOrgPerson, and thus can't easily be
synched up with
most external LDAP directories.  You'll find you'll want a
connector to synch it with any external directory.  Again,
this is not an
issue if you're willing to directly expose AD to internet use.

For me it would be a mistake to use now the "brand new" Active
Directory, but if someone could tell me where I can find proofs
of lack of compatibility (from Microsoft, there must be surely
one of two), this would interrest me.

AD seems to work just fine, if you don't mind working with
something with a
proprietary schema.  Any LDAP and S/MIME aware client we pointed at it
understood the contents just fine, so the schema does not
seem to impact
client interoperability.

Yes, certs issued from a W2K CA can be used for S/MIME, and no
less so than
certs issued from Baltimore, Iplanet or any other CA vendor or
product.  The
main issue is not will they work, but will you be able to
validate the
certs.  Unless the person issuing the cert from W2K has
provided you with
their server's cert, or they have certified their CA with the
signature of
the publicly known CAs you will not be able to easily verify
the signature
to its source.  This is not the most technically acurate way of
saying this
but I'm not awake yet.  Baltimore has preregistered there
CA with the
vendors distributing products, as has Verisign, Thaught, and
many others.
Just make certain that you have the certificates for the W2K CA,
and access
to its revocation list so you can validate properly and
you'll be fine.

Hi everybody,

Just a question :

Is there any known issues using S/MIME with
Win2000PKI-certificates ?
More generally, are Win2000 certificates usable with (and
understood by ) the others mailers (especially Lotus Notes,
Netscape, Eudora +plug-in?)

Isn't Baltimore Unicert a "better choice" due to its greater
compatibility ?

Any advices are welcome.
