Dear users of the Linux Cluster at LRZ, some accounts are unable to log in to the new MPP cluster front end nodes. We are investigating the cause, which appears to be due to a failure to connect to the authentication server. We'll keep you updated about the status via this URL. This information is also available on our web server http://www.lrz-muenchen.de/services/compute/aktuell/ali4097/ Reinhold Bader
