AddTrust External CA Root certificate expires May 30

May 27, 2020

The legacy AddTrust External CA Root certificate is scheduled to expire on May 30, 2020. 

In most cases, we anticipate no issues. However, as the date for certificate expiration approaches, you should be aware of a few potential risks that pertain to specific LDAP and OPEN/SSL configurations.  Applications that act as an LDAP client, or that are configured to explicitly trust the AddTrust CA root, may have issues following expiration of the certificate and require reconfiguration or update.
