Certificate Authority

AMT sertifikaadi Application Policy OID´i lisamisel tekkis meil huvitav probleem. Veateateks saime: “The following object identifier has already been used: 2.1.840.1.113741.1.2.3. Type a different value.“



CA väitis, et selline OID juba eksisteerib kuigi OID nimekirja kontrollides ei näinud me sellist OIDi seal tabelis. Koos Microsoftiga saime ka sellele lahenduse.

It seems that some incorrect information exists in AD. Please follow these steps to check and correct it:
1. Run this command to export AD: (I suppose the domain name is "contoso.com".)
Ldifde -f out.txt -d "CN=OID,CN=Public Key services,CN=Services,CN=Configuration,DC=Contoso,DC=com"

2. Open out.txt and see if OID 2.16.840.1.113741.1.2.3 exists. It could be similar to this:
===
dn: CN=3.4150BAD13DBF0E373C9B003794AA3307,CN=OID,CN=Public Key
Services,CN=Services,CN=Configuration,DC=Contoso,DC=com

3. Open Adsiedit.msc and find
"CN=3.4150BAD13DBF0E373C9B003794AA3307,CN=OID,CN=Public Key
Services,CN=Services,CN=Configuration,DC=Contoso,DC=com".

4. Open Properties of this object and verify the DisplayName attribute. If it is set to "Not Set", currently the Application Policy OID is not able to be displayed in the Add Application Policy Dialog box, and they are not going to be able to create a new Application Policy with the same OID because the OID already exists. Please add a value to this attribute such as "AMT Provision".
