GECo Certificate Authority
The GECo lab runs it's own certificate authority (CA), which is used to sign the certificates for various GECo web services. This may prompt warnings by some clients (browsers), since they usually expect site certificates to be signed by "trusted" corporate certificate authorities. To overcome these warnings you may include the GECo CA as a trusted authority. See the CAL wiki CA page for good instructions on importing this certificate into various clients. Also see the CAL wiki fingerprints page for good instructions on checking fingerprints.
