Graham- A couple of thoughts on this. If you want to maintain different conventions for an attribute in the respective directories (e.g. display name), then you'll want to configure the ADC to not synch that attribute. From what Al said, implementing this may differ between Exch2000 and Exch2003.
You can configure the ADC so that it replicates from AD to Exch initially (Advanced tab on the CA). It defaults the other way, based on the assumption that most organizations had Exch 5.5 around prior to AD and that the attribute data in the Exch5.5 directory was richer and authoratative. However, I don't see the real need to flip the default around. To me, the value in the ADC is the ongoing sync, not the big up-front "one-time" synch. Once you've gotten the first-time synch done, if you manage the attributes in AD then that becomes the authoratative source. So if you have data in AD that you don't want to have overwritten by Exch 5.5 on the first synch run, you can export that data to a csv file and import it into Exch 5.5 before the first run. Then the attribute values will be the same, and won't get overwritten. When you export the AD attributes, you can edit the resulting csv file to clean out objects with null values in the attribute; that way you won't overwrite a populated 5.5 attribute with a null AD attribute. You'll probably end up with one csv file per attribute to import into Exch 5.5. Yes, it's a bit of work, but I don't see a way to make both directories authoratative for an attribute on a selective basis (populated vs empty) Hunter -----Original Message----- From: Graham Turner [mailto:[EMAIL PROTECTED] Sent: Friday, July 30, 2004 9:41 AM To: [EMAIL PROTECTED] Subject: Re: [ActiveDir] AD replication from 5.5 using ADC Al, the document i reference is titled "Understanding an Deploying Exchange 2000 Active Directory Connector" - sourced from the given URL I am aware that this is for Ex2k ADC - but can find no similar document for Ex2k3 ! so i have taken assumption this is not to far off !?? your are perhaps right on "my expectation" - my initial view has been to replicate data only from the 5.5 where it is required - by implication the AD is the authoritative data source this is the rationale behind my endeavour to understand how to manage, prior to what will likely be a big hit, the data that is brought into the directory from 5.5 GT ----- Original Message ----- From: "Mulnick, Al" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, July 30, 2004 4:09 PM Subject: RE: [ActiveDir] AD replication from 5.5 using ADC > Graham, it sounds like you have different expectations of what the ADC does > for you.
