<div>Directory servers ds03.directory.cornell.edu, ds04.directory.cornell.edu, and ds05.directory.cornell.edu will have their SSL certificates updated between 7am and 9am on Tuesday, July 29, 2025. <br><br>The certs are used for secure LDAP communications to the servers (LDAPS). These are Enterprise Directory servers, not Active Directory or ADLDS. The affected service endpoints are: - query.directory.cornell.edu - internal.directory.cornell.edu Servers will be updated in a rolling fashion and they are behind load balancers so we do not expect a service outage.</div>
