The Globus Toolkit facilitates the authentication of clients against a list of trusted certificate authorities. This consists of validating the client's certificate to ensure that it was issued and signed by a trusted certificate authority. The Grid Trust Service (GTS) maintains the trusted certificate authorities or trust fabric for caGrid. In order for Globus to authenticate users against the trust fabric, both client and server caGrid installations must be synced with the trust fabric. The SyncGTS tool provides three methods for syncing with the trust fabric:
The command line approach is generally recommended for clients wishing to sync with the trust fabric. The Service Based Approach is recommended for syncing servers with the trust fabric. The programmatic approach is intended for applications who wish to sync with trust fabric on behalf for the clients who use them, removing this responsibility from the client.
