7.1.2 Information ServicesMetaCentrum runs a MetaPortal at meta.cesnet.cz, providing general informationto users and the public in its open section, as well as specific informationfor users and administrators in an authenticated section. In line with the pricepolicy of MetaCentrum, authentication is carried out through the Kerberos system.There are also extensions available for the Mozilla viewer, able to makeuse of the user’s active tgt ticket for purposes of authentication.For primary storage of information, the website of MetaCentrum makes use ofthe CVS version of administering system. The web pages are generated fromthese data (on request or automatically). This enables us to also provide an effectiveapproach to semidynamic data where pages are not generated for eachaccess, but only after a change in the primary “database”.The information structure is based on the “kerberized” openLDAP, what hasbeen fully functional and in operation since the second half of 2002. This systemprovides access to all dynamic information and user data. We have also tackledproblems associated with data replication and backup. The results described inthe technical report will be applied during the year 2003.By means of MetaPortal, users gain access to all personal data that they provide.Users can thus check all their data through MetaPortal, together with thenecessary updates and corrections. Users can also select systems to whichthey wish to gain access within MetaCentrum.The validity of accounts is limited to a single year. It is possible to extend it withthe use of MetaPortal (users need to write a short message and confirm theirpersonal data. Without this, accounts cannot be extended).The administration of personal data and account details is provided by thePerun system, fully developed within MetaCentrum. In 2002, the developmentcontinued, particularly in its administration section, used by the administratorsof individual nodes, together with the full integration with the openLDAP infrastructure.At present, the system allows for distributed confirmation of an applicationfor a new account, authorization changes, and checking and extendingaccounts and other activities, including notifications of pending requirements.7.2 Globus, MDS and InternationalActivitiesWe have installed the Globus 10 system version 2 within the main MetaCentrumsystems and activated its MDS information system, version 2.2.
