Most manufacturers are slow in implementing this protocol, although I know that Digital have started. P.S. Read my book about this, it is explained in there. David We are running DSAs from DIGITAL. But they are only able to shadow information between DIGITAL DSAs, because they use a non standard ShadowingAgreement ObjectClass to store the Agreement information in the directory (however, to transfer data DISP is used). Exists there a standard ShadowAgreement ? --------- Not as yet. The ASN.1 exists for it, but it has not been defined as an attribute type. This would be a simple task to do, but the standard's committee could not decide on where to store it in the DIT. David Or can Shadowing only take place between DSAs of the same vendor ? (which I hope has to be answered with no) ---------- Certainly not, but each vendor will determine how to configure the agreement into his/her DSA. David --Michi
