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:
- Run the command "openssl s_client -connect <host_name>:443 </dev/null > out.txt 2>&1"
- 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.
