[python-win32] ADSI and LDAP Searches

[Gooch, John]

Hey, I am converting a Perl script into a Python script, and the part where
the Perl script is searching Active Directory using the LDAP interface is
throwing me a curve ball.

Here is a search for a Windows Group in Perl:
my $hdb = Win32::OLE->new("ADODB.Connection");
$hdb->{Provider} = "ADsDSOObject";
$hdb->Open("ADSI Provider");  
$rs =
$hdb->Execute("<$adsdomain>;(&(objectCategory=Group)(name=$groupname));adspa
th;SubTree");


Here is what I have in Python so far:
    adsi = win32com.client.Dispatch('ADsNameSpaces')
    ldap = adsi.getobject('','LDAP:')
    DSO = ldap.OpenDSObject("","","", 0)

It errors on the DSO line. I am guessing that the 'DSO' Python object is the
equivalent of the Perl "$hdb" object, but I don't know the syntax. I could
be complete off-base here as the document I have found via Google don't
explain what the code is doing, so I am left guessing.


Any help would be appreciated.

Thank You,

Thankfully dependency issues like this seem to be rare....

I just checked...  And guess what... Py2exe is bundling netapi32.dll... I am
working on a new beta, so I'll test to see if it will work on XP without
netapi32.dll being bundled...  If so, then we should be 
kosher...

Good catch...  I'll have to grab dependencywalker 
to get some practice...

That's what I suspect....

It's okay....  I just miss McMillian's installer...
It's unsupported, so I've moved to py2exe...  But 
McMillian's package seemed to be better with
the dependency issues....  And offered a few
features that don't exist in py2exe... (Or at least
are not easily handled in py2exe...)

On the plus side, py2exe has handled packages lately
that I just could not get McMillian's installer
to work reliably with...  Which is why I switched...

Oh well... Progress...
