One of the various load balanced, front end LDAP servers used for service authentication stopped processing authentication requests. This would have been perceived by some users as an intermittent login failure to some applications. Some web based applications that require authentication may have been affected. Blackboard and other critical applications were not affected.
The proxy LDAP server was restarted around 3:50 PM today, and the problem was resolved.
We apologize for the service disruption.
