IGTF Server Certificates

InCommon offers IGTF server certificates for use by subscribers who are also active with the IGTF grid community. Note: Unless you are running a server as part of the IGTF grid (see the IGTF website) these certificates are NOT what you need. Request a normal InCommon server certificate instead.

The intermediate CA known as the InCommon RSA IGTF Server CA 3 was deployed on July 717, 20142023.
