Hey...just FYI...a bunch of posts came through a couple of days ago
about KDC event 11, which reminded me that I've got some myself.  I've
been using Dean's nifty little script here to identify the objects with
duplicate serviceprincipalname attrs.  Working great.

Thanks Dean!

Subject: RE: [ActiveDir] GroupBy type queries in LDAP

Since a solution hasn't manifested itself to date, I got intrigued and
tried to put this together in a simple and relatively fast shell script
... which I've enclosed as a text file (if memory serves I am able to
enclose small text files).

The script requires two args; a QUOTED "DN" and the LDAP name of the
attribute to look at.

Hope this serves your purpose, if not, I'm certain it will serve me at
some point in the future :)

Subject: [ActiveDir] GroupBy type queries in LDAP

OK, LDAP evangelists,

I need to query our customer-facing AD for a list of all the users who
share a particular attribute. Let's call that attribute "Attribute1."

So, if two people have the same value in Attribute1, I need their DN.

The trick is, that I want the results for all possible values of
Attribute1.

In SQL, I would use group by Attribute1 having count(Attribute1) >1 to
get a list of all Attribute1 values where more than one object had the
same value.
I would then join that back to the table to get a list of all the DN's
with those values of Attribute1.

Is there a way to do this with an LDAP query.

Please note that the directory contains millions of objects and
iterating through them will be painful.
