On June 14 and 22, the Office of Information Technology (OIT) will be making software changes to convert Identity Management middleware services from the old x.500 directory service to LDAP. We are moving Central Authentication Hub (CAH) services off of old directory servers so that we can retire the old servers. By retiring the old servers, we simplify our updating processes and better position ourselves for future Identity Management upgrades and projects.

There is no planned downtime to make these changes, and we expect no service interruption. The work will be performed in the morning outside of business hours. We chose to not make these changes during scheduled maintenance hours to ensure that standard problem reporting channels (e.g., 1-HELP) are available within a short time after the changes are made.OIT staff will be monitoring the change and will be prepared to revert the changes in the event that problems occur.

If service interruptions occur, the impact will be minimal. Service interruptions would only last a few minutes and would only affect a small number of users. Services that have the possibility of disruption are any services that require central authentication.

If you have any questions about the upcoming changes, please email the authentication services team at idm@umn.edu.
