        • <big> EGEE issues coming from ROC reports </big>
          1. France ROC: IN2P3-CC T1: How to publish CE authorization restriction for a VO? We restricted the access to production role for CMS and Atlas on our T1. But is it possible to publish this in order to prevent job submission from unauthorized people ?

          2. SW Europe ROC: PIC: Strange behavior of the SAM tests this weekend. Two SAM tests where send to the CEs within 10 minutes. The first was OK, the second failed without an obvious reason. This tests where executed at the end of a period where when the SRM tests were marked gray at GRIDVIEW.
        • <big>Drop of support for plain proxies</big>
          At present, gLite software is being certified by SA3 using both plain grid proxies as well as VOMS proxies. As the EGEE project has moved away from plain grid proxies to VOMS-based proxies, and SA3 is trying to make the best of its limited manpower, SA3 has proposed to the TMB (former TCG) to drop the support for plain grid proxies (i.e. generated via grid-proxy-init) in the EGEE m/w. EGEE will certify services only with VOMS proxies. Problems or bugs affecting services accessed using plain proxies will be no longer fixed. If you have any objection to this proposal please write to egee-tcg-site-rep@cern.ch before the next TMB (Wed. 18th June 2008).
        • <big> Issue with upgrade of MyProxy to gLite 3.1</big>
          The myproxy-server daemon will hang when it is started from a non-interactive shell. It appears to work fine when started from an interactive shell.
          The cause of the problem is that the myproxy-server has been linked against a multi-threaded flavor of Globus instead of the single-threaded flavor expected by the code.
          We have asked the VDT project for an urgent rebuild of the code against the correct Globus flavor. We will certify the new RPM and release it to production with high priority.
          In the meantime sites can either stay with the MyProxy service provided by gLite 3.0, or restart the myproxy-server interactively as needed.
