SSO Fails After Completing Disaster Recovery Operation

Problem    When a user completes a disaster recovery operation, SSO fails due to expired certificates.

Possible Cause    Existing SSO certificates were installed before the application was installed.

Solution    Reinstall SSO certificates after completing Disaster Recovery Operation. After you perform your restoration on the disaster recovery system, sign in to the Administration site and select Settings > Security > Certificate > SSL Certificate > Generate CSR.Under More Options, select Download CSR to download the generated CSR. Use the CSR to obtain a new SSL Certificate. Refer to the "Generating SSL Certificates" section of the Administration Guide for more information. Import your new SSL certificate by selecting Settings > Security > Certificate > More Options (Import SSL Certificate). Import the same SSL certificate into your ADFS (Active Directory Federation Service) for the site URL's relay party.
