LDAP how to troubleshoot Certificate do not match

 

CAUSE

Certificate uploaded into workfront instance is not the same as the certificate being presented by the LDAP or AD system.

 

SOLUTION

Find and Upload the correct Certificate.

note- Certificates can be stored in multiple places so there is no way for Workfront to be able to tell  where to locate the correct certificate.
