Symptoms

Assume that you have a Windows Server 2012 computer that has the certification authority role (CA) installed. Additionally, assume that the CA name contains space characters. However, when a certificate is issued from this CA, the CA does not replace the space characters with "%20" in the URL paths for certificate revocation list (CRL) distribution points and authority information access extensions.

Note You can open the certificate and then click the Details tab to check the CRL Distribution Point field and Authority Information Access extensions.

You expect that the CA replaces all the space characters with "%20" in the URL paths for the CRL distribution points and authority information access extensions.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More Information

Request for Comments (RFC) specifications for URL paths that are published in issued certificates require URL encoding of special characters, and this includes space characters. Many clients, such as Windows clients, can correctly access URLs that are not encoded, and these clients are not affected by this problem. However, some third-party devices, such as some Cisco iOS devices, require the URLs to be encoded according to the RFC specifications for such devices to use these URLs correctly to perform certificate revocation checking.
