  1. gLite authentication and authorization Discipline: Grid Computing, 07/08-2 Practical classes Inês Dutra, DCC/FCUP

  2. Certificates • INSPECTING PERSONAL CERTIFICATE • Look inside your certificate grid-cert-info • Important information • Creation and expiration date • Name and subject of the CA • Common Name (CN) of the certificate owner • Certificate subject

  3. Login • Creation of a proxy with voms extensions • This step is like doing a login on the grid. voms-proxy-init --voms gilda Attention: use the same pasword you used to retrieve your certificate

  4. Checking the VOMS proxy • CHECK YOUR VOMS PROXY • To get info about your proxy voms-proxy-info -all • It shows two different lifetimes: • First is related to the proxy itself • The second one is referred to the AC infos added by the VOMS server. • Important: your proxy has lifetime of 12 hours

  5. Proxy • Register a long living proxy in the MyProxy server (grid001.ct.infn.it) • Allows you to create and store a long term proxy certificate myproxy-init --voms gilda • The –s option allows you to specify the name of the myproxy server you want to contact myproxy-init --voms gilda –s grid001.ct.infn.it

  6. Still myproxy-init • Register a long living proxy in the MyProxy server (grid001.ct.infn.it) • The –l option allows you to create and store a long term proxy with a name specified by the user myproxy-init --voms gilda –s grid001.ct.infn.it –l GILDA_TUTOR • Each user can create and store several proxies in a myproxy server, but each remote proxy is linked to the specified username

  7. Still myproxy • Gather information about the proxy in the MyProxy server • If in your UI there is no local proxy, it´s not possible to be authenticated in the myproxy server • In this case it is needed to get a delegate proxy from the MyProxy server or create a local proxy with voms-proxy-init

  8. Get a delegated proxy from the MyProxy server • It allows you to get a proxy from the myproxy server • Destroy the proxy in the local machine and verify it doesn´t exist anymore voms-proxy-destroy voms-proxy-info couldn´t find a valid proxy

  9. Still proxies • Get a delegated proxy from the MyProxy server • Now in your UI (virtual o real), there is no local proxy. • To get a proxy from the myproxy sever myproxy-get-delegation –s grid001.ct.infn.it

  10. Still proxies • Get a delegated proxy from the MyProxy server • With –d option myproxy-get-delegation –s grid001.ct.infn.it –d • Verify now that the user has a local proxy voms-proxy-info

  11. Still proxies • Destroy remote proxy • You can destroy your remote proxy myproxy-destroy –s grid001.ct.infn.it • Check your remote proxy myproxy-info –s grid001.ct.infn.it

  12. Still proxies • Destroy remote proxy • Destroy your remote proxy with -d myproxy-destroy –s grid001.ct.infn.it -d • Check your remote proxy with -d myproxy-info –s grid001.ct.infn.it -d

  13. Still proxies • Destroy remote proxy • Destroy your remote proxy with -l myproxy-destroy –s grid001.ct.infn.it –l GILDA_TUTOR • Check your remote proxy with -l myproxy-info –s grid001.ct.infn.it –l GILDA_TUTOR
