What do these %Variables and option numbers mean? Not sure what I’m talking about? Take a look at the screenshot below:
How are these values determined? Well for AIA’s, the values are based off the table below:
| Option Number | Description |
| 0 | No Options Defined |
| 1 | Automatically Publish CA Certificate to this location |
| 2 | Include in the AIA extension of issued certificates |
| 32 | Include in the online certificate status protocol (OCSP) extension |
From our screenshot above and combining the information from the table, we can work out how the values are calculated:
| Value | Description |
| 1 | Automatically Publish CA Certificate to this location |
| 2 | Include in the AIA extension of issued certificates |
| 3 | Automatically Publish CA Certificate to this location Include in the AIA extension of issued certificates |
What about the percentage values (variables) such as the ones in the screenshot below?
| Variable | Variable Display Name in CertSrv MMC | Description |
| %1 | <ServerDNSName> | The DNS name of the certification authority server |
| %2 | <ServerShortName> | The NetBIOS name of the certification authority server |
| %3 | <CaName> | The name of the Certificate Authority |
| %4 | <CertificateName> | The renewal extension of the certification authority |
| %6 | <ConfigurationContainer> | The location of the Configuration container in Active Directory |
| %7 | <CATruncatedName> | The “sanitized” name of the certification authority, truncated to 32 characters with a hash on the end |
| %11 | <CAObjectClass> | The object class identifier for a certification authority, used when publishing to an LDAP URL |
