          1. ROC DECH: DESY: Issue with glite-WN-3.1.31-0
            ATLAS complained to us about problems using their software. It seems that this happened after the deployment of glite-WN-3.1.31-0, which introduced the grid-cm package, that badly interferes with the ATLAS Python installation, which seems to be not properly set up.
            We want to make the operations meeting aware of the problem since it might affect many other sites. We strongly recommend to go for a central solution in ATLAS and not patching around on the level of sites.
            Some item can be found in the ROC DECH support portal: https://dech-support.fzk.de/ws/overview.php?quali=open&resultlist=1&ticket=3931

          2. ROC DECH: DESY: IRAN CA issue
            There is rumors that the German Ministry of Science has requested (?) will request to all German resource providers to make sure that the resources cannot be used by users from Iran.
            This is at least a matter for CMS sites, because they have partners from Iran in the VO using certs signed by the Iranian CA.
            What is know about this in EGEE? Is there any advise how to solve this technically in case sites would need to fulfill such a request?
            Removing the Iranian CA would let to failing SAM tests because proper installation of all participating CAs is checked. That btw does not make sure to exclude Iranian citizens since do not have certificate from the Iranian CA.

        • <big> gLite 3.0 VOMS servers - VOMS-client incompatibility on the way! </big>

          The following VOMS servers are running gLite 3.0 versions:
          • https://grid12.lal.in2p3.fr:8443/vomses ( 16 VOs )
          • https://voms.gridpp.ac.uk:8443/vomses ( 20 VOs )

          NB: This list may not be complete.

          As announced on 3 July*, there is a version of the VOMS-client currently in certification which is incompatible with the 1.7.x (gLite 3.0) versions of the VOMS server.

          These VOMS servers must be upgraded as soon as possible.

        • <big> MATLAB available on the EGEE grid </big>

          As announced last week*, the MATLAB product from Mathworks has been integrated and extensively tested with gLite. Any sites interested in integrating MATHLAB with gLite in their site should read the announcement* and follow the instructions there. For technical information and other material regarding MDCS and gLite integration you can check these resources.
