svn co Error: Server certificate verification failed: issuer is not trusted

When attempting to sync a repo to a server or to your desktop you will receive an error if the certificate being used to protect the HTTPS repository URL is not issued by the proper authority. Many companies generate their own certificates for repository URL’s especially if the repository is primary used internally. In this example I was attempting to sync a repository using SVN to a folder on the desktop of my Macbook Pro running OSX Mountain Lion. Below I describe the error in more detail followed by resolution to the svn certificate error.

How To Set a Root CA to Untrusted on Mac OSX

I decided to make a quick post on how to set a trusted root CA to untrusted in Mac OSX. As some people may or may not know, one of the root CA authorities was recently hacked and several rouge certificates were issued including one with a domain name of Now DigiNotar, which is the company in question, claims that the have revoked all the rouge certificates and all is well. However, me being involved in infosec and security I would rather not take any chances so I decided to set DigiNotar to a “trust never” level on my machine for the time being. Below I will outline the few simple steps to do this for any certificate authority on Mac OSX.
