Free OCSP server for testing purposes?

Can anyone recommend a free and simple OCSP server for Windows or Linux?

From serverfault StackedCrooked

• The best free OCSP server is in the OpenCA package. Here is an example of creating a custom OCSP message. If you like java then you should use EJBCA.

  I think windows has an OCSP server in the windows 2008 enterprise edition. I know it has other parts of the PKI. This isn't free.

  davey : There is also Fedora/Redhat's ''Dogtag'' http://pki.fedoraproject.org/wiki/PKI_Main_Page

  StackedCrooked : @unknown: Thanks, that looks very interesting. I'll give it a try tomorrow!

  StackedCrooked : @The Rook: I was able to glue a solution using the OpenCA library. See this post: http://serverfault.com/questions/131983/openssl-how-to-setup-an-ocsp-server-for-checking-third-party-certificates. Thanks for the suggestion!

  Rook : @StackedCrooked Thats awesome! OpenCA rocks, i'm glad i could help.

• Windows Server 2008 and 2008 R2 Enterprise Editions both have OCSP as an option when you install the AD Cert Services. You can use both for testing purposes for 180-days. Download available from Microsoft.
