I do have an OID from Microsoft. I knew that picking my own LinkID had to be a bad thing, but I didn't know of any other way to get it. Can you expand on autolinking?
Thanks Joe, BTW this is the Joe that you met at DEC in Virginia. This is my first Post! Thanks for letting me know about this distribution list. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of joe Sent: Friday, March 04, 2005 1:38 PM To: [email protected] Subject: RE: [ActiveDir] Creating a backlink and forwardlink Small correction, you will register your prefix and OID (or even request an OID) from MS and then you can request a linkid pair, DO NOT create your own linkid values. Additionally if this is on K3 or AD/AM you can use autolinking and not use a specific linkid value. See http://blogs.msdn.com/efleis/archive/2004/10/12.aspx For a writeup. I was talking with Eric one day and he mentioned it and I was like, "WHAT? No I never heard of that!" so he documented it in his blog. joe -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sakari Kouti Sent: Friday, March 04, 2005 4:31 PM To: [email protected] Subject: RE: [ActiveDir] Creating a backlink and forwardlink Hi Joseph, I tested this for the purposes of our "Inside Active Directory" book. You should define the linkID attribute for both of your attributeSchema objects. The forward link must have an even positive non-zero number (for example, the member attribute has 2) and the back link must have a larger-by-1 odd value (for example, the memberOf attribute has 3). A forward-link attribute must use one of the following syntaxes: DN, DN with Unicode string, DN with binary, access point DN, and OR name. A back-link attribute must be of syntax DN. The two linkID numbers must not conflict with any other attributes. You can find free numbers manually, if just for your own use, or programmatically, if the installation must work in any forest. The platform SDK has a sample C++ code for this. You must first create the forward link, and then the back link. The back link must be multivalued (and the forward link may be). In addition, the platform SDK says that "By convention, back link attributes are added to the mayContain value of the Top abstract class. This enables the back link attribute to be read from objects of any class because they are not actually stored with the object, but are calculated based on the forward link values." For production purposes, it might be a good idea to register your link ID pair with Microsoft at http://msdn.microsoft.com/certification/ADLinkID.asp Yours, Sakari ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Isenhour, Joseph Sent: Friday, March 04, 2005 10:45 PM To: [email protected] Subject: [ActiveDir] Creating a backlink and forwardlink I'm trying to figure out how to extend our schema with a forwardlink attribute and a corresponding backlink attribute. I understand how to create an attribute with a DN syntax and I even understand how the two are linked in Active Directory. What I don't know is what to put in my LDIF to make AD link them. Has anyone ever done this?
