[Read more…] about June 2022 Windows Server PatchingWe experienced a failure of EECS LDAP authentication, from about 5:50pm to 10:30pm, due to routine patches changing some file permissions for saslauthd. The issue has been corrected, and LDAP authentication is working again.
The problem may have been most noticeable when attempting to login to various EECS web forms (e.g. system registration or user account request forms).

[Read more…] about May 2022 Windows Server PatchingWe are implementing an update to Group Policy that affects our Windows Domain Controllers this morning at 10am. No impact is expected on end users, but we are mindful that a similar change last week caused an unexpected problem with LDAP-auth (see https://iris.eecs.berkeley.edu/news/resolved-incidents/eecs-ldap-logins-not-working/).
This update improves the security profile of our Domain Controllers. In particular, we are removing explicitly-listed Null Session Named Pipes, as is best practice.
We are investigating an issue with EECS Windows Domain Controllers, preventing LDAP-to-Windows password passthrough from working. This affects all systems that rely on EECS LDAP for authentication, including various webpages, the EECS-Secure wireless network, and linux machines configured to use EECS LDAP. The issue began at approximately 7:45PM on 4/20.

[Read more…] about April 2022 Windows Server PatchingBeginning April 5, 2022, you will start to see changes in the CalNet 2-Step process for browsers (e.g., Apple Safari, Google Chrome, Mozilla Firefox, etc.). The upgraded workflow provides a simplified and accessible Duo login experience and offers a redesigned visual interface with security and usability enhancements.
[Read more…] about New CalNet 2-Step Look for BrowsersOur current NetApp fileservice architecture has multiple hostnames pointing to the same IP address. As a performance measure, we will be introducing some new IP addresses for some of the hostnames, very early on Tuesday, March 15. If you have any custom firewall rules for the current IP addresses, you may need to modify them to include the new ones.
This change should not create any interruption in service. Any active mounts of the former IP addresses will continue to work.
