Some of our Linux servers are unable to use the Chemistry Active Directory to authenticate logons this morning. We are still debugging this problem. Users are unable to SSH to linuxfs, and the CBC Computer Support staff are unable to use the trouble ticket system. If you are waiting for a response to a particular problem, or need help this morning with any other computing needs, please call 614.292.0848.
2:10 p.m. Update: All services have been restored. [Tech summary] Some of the older and/or web Linux servers use LDAPS. When the SSL cert for the LDAP server expired, the server could not renew it because the certificate authority needed to check the revocation list, but the certificate revocation list cert was itself expired. We had to boot the offline CA to get a new list cert.
