Dept Webserver Issues, Restarting at 12noon

by

The Department webserver which hosts people.eecs.berkeley.edu and most other project websites in the department has hung twice today, once around 8:30am and once around 10:15am. It will be patched and restarted at 12 noon.

A new version of the Apache web server software has just been released which fixes a vulnerability that could be responsible for the problems. Apache will be patched and restarted today at noon, and the webserver will be unavailable for approximately 10 minutes during this time.

LDAP upgrade tonight, 6pm

by

The LDAP servers behind the load balancer for ldap.eecs.berkeley.edu will be upgraded tonight between 6pm and 8pm. Beginning at 6pm a final backup will be made of the data on the old servers, loaded into the new servers, and then the old servers will be retired. No service interruption is expected as the load balancer will be used to route requests to the right machines during the transition.

This is a change in both operating system and OpenLDAP software version. We have been testing the new servers for several months and do not expect any problems, but please inform help@eecs if you have any issues after the upgrade.

One enhancement is the addition of the memberOf overlay. This puts a new attribute (memberOf) in each person’s record to reflect LDAP groups they are members of, and is needed for some authorization situations.

Unix groups and automount maps are now also published in LDAP. Documentation is being prepared which will describe how to configure sssd on Unix/Linux machines to use these new OUs in LDAP instead of NIS.
