I just realised that legacyExchangeDN was a bad example to pick in my email below because the syntax is "Case Insensitive String" and not "Distinguished Name". I guess this is to support the ADCDisabledMail value, which is clearly not DN format.
Sorry Joe :-) Tony PS. This has been a great thread. I learned that linked attributes are indexed by default and that Joe maintains good bodily hygiene! -----Original Message----- From: Tony Murray [mailto:[EMAIL PROTECTED] Sent: Dienstag, 9.

You can still use a wildcard where the beginning of the value is known, e.g. (&(|(objectclass=contact)(objectclass=group))(|(legacyExchangeDN=/o=MyCo/ou= MyOU/*)(legacyExchangeDN=ADCDisabledMail*)(isDeleted=TRUE))) I think this is where the indexing would help. Tony ---------- Original Message ---------------------------------- From: "joe" <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] Date: Tue, 9 Nov 2004 06:03:07 -0800 You will have a little DIT growth, creation of new mailboxes might be impacted a little in terms of speed as insertion of the attribute might be a trifle slower (nothing you would notice I expect unless doing a ton of new creations quickly with MT C code and still you could blame it on the RUS faster than blaming it on the indexing). Anything that searched on that attribute would possibly be more efficient or be quicker. You still won't be able to do wildcard searches because it is a DN attribute. What are you looking to get out of it? Or to put it another way, why do you think you should do it? Overall in the end, MS and pretty much anyone is going to say you need to test it in your test lab with a comparable test data set as production to really know specifically what it will do. joe _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Holland Matthew BC GB Sent: Tuesday, November 09, 2004 4:36 AM To: [EMAIL PROTECTED] Subject: [ActiveDir] Indexing an attribute Hi all, Does anyone know the potential impact of indexing an attribute in Active Directory? The attribute is HomeMDB, it's Single Valued and is a member of the PAS (We have approx 17,000 Mail Enabled User objects in Active Directory).
