Re: ADAM and Windows Address Book

Yes, the issue appears to be with the implementation of WAB and not a
problem with ADAM or SSPI per say. SSPI is certainly capable of using the
current thread's credentials OR using specific credentials, but WAB is not
taking advantage of the latter for some reason, even though the UI would
seem to indicate that it would.

If specific credentials need to be used, it seems to me that the ony
solution for Rich is to create a service account in ADAM and use that (or
create bindProxy objects for each user if it is important that each user use
their own passwords). This would accomodate the simple bind case, which WAB
seems to work with. Since SSL is in use, this would be secure.

I really appreciate your testing and results.

So let me see if I understand it.

Since I need a Windows login, the simple bind is of little interest.

If I want a Windows login to ADAM from Address Book, I must be logged
into a domain account.

That is because the SSPI logon uses the credentials of the logged on
account. If the logged on account is not a domain account, then no
authentication can take place because ADAM does not authenticate accounts
that are not either ADAM accounts or Windows accounts for the domain that
ADAM is in.

The bind method distinguishes for ADAM between windows accounts (domain or
local to the ADAM instance) and native ADAM accounts. An SSPI connection
must be a windows account from ADAM perspective and the only authorities
ADAM can appeal to for auth of the account are domain (joined to or
trusted)
and the OS ADAM server is running on. If the only credentials WAB can
offer
over SSPI are those of the logged on account that runs WAB and if that
account
is not auth'ed by an authority ADAM has access to then there's no access.


A conclusion is: The username/password supplied to the Address Book
properties pages is not used for authentication to the ADAM instance -
ever! If I report this to MS, will it be considered a bug? Are any
hotfixes known for this?

The username/password in WAB can be used for a simple bind (with or
without
SSL) using credentials of an account that is native to ADAM. SPA must be
unchecked for this to work. WAB is clunky, the real problem is as JoeK
pointed
out that the use of credentials and the selection of "SPA" in the
interface should
be mutually exclusive (and also no one knows what "SPA" means).
IMO WAB and the Outlook LDAP Address Book could both do with a refresh;
googling around it seems like WAB may be replaced in vista.

I believe Address Book fails the same way when pointed directly at an
Active Directory domain rather than an ADAM LDAP instance!

Pointing WAB at a DC the only authority is the domain (or trusted domain)
no local windows SAM auth, clearly any non domain account will fail to
auth.
However unchecking SPA and entering domain credentials (in appropriate
form)
will work against AD (SSL may be required depending on policy) as the
simple
bind with windows credentials will be authenticated by AD.
