Intermittent LDAP authentication failures – Friday, April 12, 2013 10:28 AM AM

One of the LDAP servers used to authenticate users logging in to my.ryerson, Blackboard, eHR, Confluence, Jira and other applications experienced intermittent problems related to the amount of memory available (Java Virtual Machine heap size).  This caused an intermittent response issue for these applications.    The server has been taken out of the load balanced cluster of ldap servers.   We are working with Oracle to tune the JVM heap size and resolve the issue.

We apologize for the service disruption.
