Temporary LDAP authentication failure

by

We 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).
