Ok, I'll take a stab. I'm hoping that this scenario is what we are
actually talking about. I'm not really sure if we are still helping the
original poster either, but here goes...
, given a container:
cn=users,dc=joe,dc=com
a user (standard AD schema)
cn=joe,cn=users,dc=joe,dc=com
This works:
Set cont = GetObject("LDAP://cn=users,dc=joe,dc=com";)
Set usr = cont.GetObject("user","CN=joe")
wscript.echo usr.description
This fails:
Set cont = GetObject("LDAP://cn=users,dc=joe,dc=com";)
Set usr = cont.GetObject("person","CN=joeschematest")
wscript.echo usr.description
Questions:
Is this the same basic thing Joe mentioned?
Is this the designed behavior or a bug?
I still think this is the designed behavior. I just want to make sure I
haven't missed the whole point here. Eric, please debug at your
leisure. :)

If someone has an active repro, I can debug it. Ideally a repro that
could be sent to me (using any class inheritance, I'm not picky, I just
want the snip of code to run), second best is a repro in a test
environment you don't mind me logging in to.
Joe, can you repro with something like 'top' if you target a user
specifically? In theory it should repro with any class that appears
later in the list, if my understanding of the original issue is correct?

Hmm,
Is this:
Set cont = GetObject("LDAP://cn=users,dc=joe,dc=com";)
Set usr = cont.GetObject("user","CN=joeschematest")
wscript.echo usr.description
really supposed to work for anything but the "leaf" level object class?
I would expect you'd get the desired result if you did:
Set cont = GetObject("LDAP://cn=users,dc=joe,dc=com";)
Set usr = cont.GetObject("joewarefromuser","CN=joeschematest")
wscript.echo usr.description
I know if you did the equivalent search with the same filter in ADO/.NET
DirectorySearcher, you'd get the same result as your search. I honestly
don't know what the behavior of IADsContainer::GetObject is supposed to
do. It seems reasonable that it might work either way to me. Like I
said to Al, I never use that in .NET, I just search for stuff.
We could always run it up the flagpole with the DS API guys if anyone
really thinks it is a problem. I'm not sure I do.

Oh I have seen this before. Figured it for an ADSI bug. I think at the
time
I was having a particularly hard time to get MS to admit to bugs so I
never
submitted it.
Anyway, if the issue is the same, the issue I saw was with classes
derived
from some other well known base class.
For instance, say you derive the joewareFromUser class from user.
dn:CN=joewarefromuser,CN=Schema,CN=Configuration,DC=joe,DC=com
>objectClass: top
>objectClass: classSchema
>cn: joewarefromuser

Then you create an object of this class
C:\temp>adfind -default -f name=joeschematest

1 Objects returned
This object clearly has user in the set of objectclasses. You can
further
prove it like this
C:\temp>adfind -default -f "&(name=joeschematest)(objectclass=user)" -dn
AdFind V01.26.00cpp Joe Richards ([EMAIL PROTECTED]) January 2005
Using server: 2k3dc02.joe.com
Directory: Windows Server 2003
Base DN: DC=joe,DC=com
dn:CN=joeschematest,CN=Users,DC=joe,DC=com
1 Objects returned
However if you run this simple script:
Set cont = GetObject("LDAP://cn=users,dc=joe,dc=com";)
Set usr = cont.GetObject("user","CN=joeschematest")
wscript.echo usr.description
You will fail with
C:\temp\test.vbs(2, 1) Active Directory: An unknown directory object was
requested
Interesting note on the return order, when looking at the return order
of
objectclass I have always seen it returned from the DC in hierarchical
order
of the classes. I.E. Top is always the top, anything derived directly
from
top is directly under top, something derived further down the chain is
under
the object type it is derived from, etc. The order being displayed below
is
interesting, I expect if you did a <cough>network trace</cough> you
would
see the order correctly and something else is tossing it around on you.
However, ~Eric is 1000% correct in you don't depend on order either of
what
AD returns for objects (unless server side sort control specified) nor
the
values in a single attribute. I wonder if the ADSI people are simply
looking
at the last objectclass value? Otherwise, how can they say my object
isn't a
user?

Based on the code presented, it looks more like a bug in .NET. That's
exactly how the iadscontainer::getobject method is supposed to be used.
If
there is any order dependency, it's with .NET, but I would not have
expected
it to care about the order.
I'd post this to a vb.net newsgroup and see what comes back. Unless Joe
K.
is around and sees something off the bat :)

We don't guarantee the order that a set of values in a given attribute
is
returned to the client. That said, if you depend on order, you'll have
problems now or in the future. It's not a matter of if, only when. :)
You want to make any code you have which relies on order become order
insensitive. That should resolve this issue if I understand it
correctly.

Subject: [ActiveDir] LDAP and Win2003 Question
Hi
In the current system we used to have business layer (accessing user
details
in LDAP) and LDAP running on two servers, both of which were Windows
2000.
Recently we have migrated business layer server to Windows 2003 machine.
Now
we have problem. We can't access data of some of the users.
The business layer code retrieving user details is written in VB and as
follows:
Dim oDS As IADs
Dim sDN As String
dim moUsers As IADsContainer
sDN = "LDAP://ldapserver:389/ou=users,o=abc,c=nz";
Set oDS = GetObject("LDAP:")
Set moUsers = oDS.OpenDSObject(sDN, "cn=admin,o=abc,c=nz",
"Password",
0)
Set oDS = Nothing
Dim oPList As IADsPropertyList
Dim oUser As User
Set oPList = moUsers.GetObject("inetOrgPerson", "cn=myUserName")
If oPList Is Nothing Then
RaiseError
Else
Set oUser = New User
oUser.Initialise oPList
Set GetUser = oUser
Set oUser = Nothing
End If
When viewing user details in LDAP (we are using JXplorer tool) there is
a
minor difference between the way the users' data is displayed for those
users that we can retrieve details for and those that we can't. Besides
the
standard object classes (top, person, organizationalPerson and
inetOrgPerson) we also have custom classes. These are abcOrgPerson,
abcOrgPerson2 and nxAccountInfo.
The users that we can retrieve data for have these classes displayed in
the
following order:
nxAccountInfo
abcOrgPerson2
abcOrgPerson
inetOrgPerson
top
person
organizationalPerson
For the "non-working" users this order is:
inetOrgPerson
nxAccountInfo
abcOrgPerson2
abcOrgPerson
top
person
organizationalPerson
I have tried to manually change the class order but it did work. I am
not
quite sure why the order is different. The line of code that fails is
Set oPList = moUsers.GetObject("inetOrgPerson", "cn=myUserName")
If I change "inetOrgPerson" parameter to "abcOrgPerson2" then the
"non-working" users' details can be retrieved but not the "working"
users'
details. So it seems that the class order matters for Windows 2003 (LDAP
is
still sitting on Wind2000 machine however). This same scenario runs
without
problems from the Win2000 business layer machine.
If anyone can share any advice or ideas it will be highly appreciated. I
have not had much experience with Active Directories and it's a mystery
for
me.
Thanks
