Forms authentication rule creation fails due to certificate issue

Summary:  After configuring Forms Authentication rule, the Admin Console shows the error:

java.security.cert.CertificateException: Certificate chain verification failed. For CAs with CRLs: there were no CAs with CRLs.; For CAs without CRLs: java.security.cert.CertPathValidatorException: algorithm check failed: MD2withRSA is disabled


Cause:  Root certificate of the content server is signed with MD2 Algorithm.


Troubleshooting: To determine if the root certificate is signed with the MD2 Algorithm follow these steps: 

  1. Run the command "openssl s_client -connect <host_name>:443 </dev/null > out.txt 2>&1"  
  2. In the above "out.txt" file check whether the signature algorithm is "md2WithRSAEncryption".

Fix: Replace the root certificate on your content server with a certificate signed with SHA1 Algorithm.
