GT 4.0 MyProxy: Developer's Guide

1. Introduction

We recommend using the CoG Kits when developing with MyProxy.

2. Before you begin

2.1. Feature summary

Features new in release 4.0

  • This is the first Globus Toolkit release that includes MyProxy.

Other Supported Features

  • Users can store and retrieve multiple X.509 proxy credentials using myproxy-init and myproxy-logon.
  • Users can store and retrieve multiple X.509 end-entity credentials using myproxy-store and myproxy-retrieve.
  • Administrators can load the repository with X.509 end-entity credentials on the users' behalf using myproxy-admin-load-credential.
  • Administrators can use the myproxy-admin-adduser command to create user credentials and load them into the MyProxy repository.
  • Users and administrators can set access control policies on the credentials in the repository.
  • If allowed by policy, job managers (such as Condor-G) can renew credentials before they expire.
  • The MyProxy server enforces local site passphrase policies using a configurable external call-out.

  • None

2.5. Security considerations

You should choose a well-protected host to run the myproxy-server on. Consult with security-aware personnel at your site. You want a host that is secured to the level of a Kerberos KDC, that has limited user access, runs limited services, and is well monitored and maintained in terms of security patches.

For a typical myproxy-server installation, the host on which the myproxy-server is running must have /etc/grid-security created and a host certificate installed. In this case, the myproxy-server will run as root so it can access the host certificate and key.

3. Architecture and design overview

The MyProxy system architecture and design is described in the following two publications:

4. Public interface

The semantics and syntax of the APIs and WSDL for the component, along with descriptions of domain-specific structured interface data, can be found in the public interface guide.

5. Usage scenarios

MyProxy provides a solution for delegating credentials to Grid portals to allow the portal to authenticate to Grid services on the user's behalf. A Grid portal is a web server that provides an interface to Grid services, allowing users to submit compute jobs, transfer files, and query Grid information services from a standard web browser. For example:
