ActiveDirectoryMembershipProvider woes

T

Thomas

Ok, I've run into the same problem at a different company. Some time ago I
posted this:
http://groups.google.com/group/micr...ecurity/browse_thread/thread/d6d44686f14fdf61

The short version is that I'm setting up a site using FormsAuthentication
and the ActiveDirectoryMembership provider. I suspect given the "wonderful"
error messages that I'm getting that the user account I was given is missing
some permissions somewhere. The problem is that tracking down what
permissions are missing is a serious bear. At the last company where I ran
into this problem, they punted and made the user used for authentication a
Domain Admin because we could not track down the problem.

I'm really trying to find an actionable solution that I can give to
relatively inexperienced domain admin to fix. To that end, I'm trying to use
the acldiags and dsacls to hopeful detemrine what is missing but I can't
make heads or tails of the output.

Here is the output from dsacls run from a command prompt as the user I'm
trying to use for authentication (domain has been changed obviously). This
is a 2003 Domain as far as I can tell.

As a following up, I did find this:
http://world.episerver.com/Document...-to-Use-Active-Directory-Membership-Provider/

Which lists out the permissions, but connecting the permissions it states
that the auth user needs and determining which ones it doesn't on what is
trickier.

Is the Domain Users group part of the Pre-Win2K compat access group? In
many cases permissions are delegated to the Pre-Win2K group but in some
domains the Domain Users group is not included in this group so normal users
only end up getting the permissions that are delegated to Authenticated
Users instead. This may be part of your issue.

Another approach would be to consider trying the ldp.exe tool to connect to
the directory, bind with the creds of your service account and then try to
search for users in the directory and see what attributes can be returned.
That may shed some light.

Any reason why you need to use the AD membership provider? Can you skip the
forms auth and just use Windows auth instead?

Domain Users are indeed members of the Pre-Windows 2000 Compatible Access
group as are Authenticated Users and Exchange Domain Servers.

I used the ldp tool to query for a UPN I know to exist (verified via the
ADSI tool). I used the following filter:
([email protected]) and I got the following:

***Searching...
ldap_search_s(ld, "DC=co,DC=foo,DC=com", 2,
"([email protected])", attrList, 0, &msg)
Error: Search: Referral. <10>
Server error: 0000202B: RefErr: DSID-0310063C, data 0, 1 access points
ref 1: 'CO.FOO.COM'

Result <10>: 0000202B: RefErr: DSID-0310063C, data 0, 1 access points
ref 1: 'CO.FOO.COM'

Matched DNs:
Getting 0 entries:

Notice that they have remapped the UPN from co.foo.com to just foo.com.
Regardless, I'm not sure what to make of the results.

Ok, I think I'm closer. In the ldp search, I checked "Chase Referrals" and
that found the user. Which leads me to believe that the AD Membership
Provider does not chase referrals and thus cannot find the user. Is there a
way to know whether the AD Membership Provider chases referrals? Is there a
way to force it to do so if it does not?

To answer the earlier question, we have a custom role provider and getting
it to work with Windows Auth was problematic. We could of course try again,
but I found that Windows Auth does not behave like a "typical" forms auth
provider. IIRC, the browsers do not behave nicely with Windows Auth.
Something that MS did to IE causes Windows Auth to still throw up a login
dialog even if the user is on the domain (or even the same machine as IIS.)

According to Schackow, the ADMP does not chase referrals, so I'm going to
try to narrow the container search by the ADMP and see if that fixes the
problem.

Ok, it sounds like you have a multi-domain forest involved here. I'm not
sure if the ADMP can use the global catalog or not, but that is usually the
appropriate solution for dealing with multi-domain issues.

Win Auth *should* work fine with domain joined machines. Usually when it
doesn't, it is an IE config issue. Things can get wonky on the public
internet as you can't get Kerb auth in that situation since the DC is not
available to get the service ticket from, but NTLM should still work. In
terms of making it work with a custom role provider, it really should just
be a case of taking the user identifier provided by the authentication
mechanism to look up the user's roles, right? So I wouldn't think that part
would be a huge issue. However, if you can't get the browser behavior you
are looking for in a reasonable way and really want the forms auth, then
trying to get ADMP working is probably the thing to do.

Best of luck!
