Authentication and Authorization INSPECTING PERSONAL CERTIFICATE .globus: your personal certificate, two separate files (public and private keys)  You need them for the authenticated connections with all the other elements.  Check the permissions (you won´t be able to create a proxy if they are wrong) ls –l.globus -rw-r--r--usercert.pem -r userkey.pem

Authentication and Authorization 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

Authentication and Authorization Creation of a proxy with voms extensions  This step is comparable to a login on the grid. voms-proxy-init --voms gilda

Authentication and Authorization 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 12 hours of live

MyProxyUse 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

MyProxyUse Register a long living proxy in the MyProxy server (grid001.ct.infn.it)  The –d option allows you to create and store a long term proxy with your DN. myproxy-init --voms gilda –s grid001.ct.infn.it -d  Without this option, the name of the stored proxy is the same of the user in the local machine

MyProxyUse 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

MyProxyUse Gather information about the proxy in the MyProxy server  You can get info on myproxy server about your proxy myproxy-info –s grid001.ct.infn.it  If the credentials have been initialized with the –d switch, you also have to specify it when using myproxy-info myproxy-info –s grid001.ct.infn.it -d

MyProxyUse Gather information about the proxy in the MyProxy server  If the credentials have been initialized with the –l switch, you also have to specify it when using myproxy-info myproxy-info –s grid001.ct.infn.it –l GILDA_TUTOR  Note the differences in the usename of each proxy

MyProxyUse Gather information about the proxy in the MyProxy server  I f in your UI there is no local proxy, it´s not possible to be authenticated in the myproxy server  In this case is needed to get a delegate proxy form the MyProxy sever or create a local proxy with voms-proxy-init

MyProxyUse Get a delegated proxy from the MyProxy server  It allow 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

MyProxyUse 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

MyProxyUse 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

MyProxyUse 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

MyProxyUse 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

MyProxyUse 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
