How do I fix the LDAP SSL error, “java.security.cert.CertificateException No subject alternative names present”, in WebSphere Application Server traditional?
After upgrading WebSphere Application Server, the appserver will not start, and the SystemOut.log reports the following error:
com.ibm.websphere.wim.exception.WIMSystemException: CWWIM4520E The 'javax.naming.CommunicationException: myldap.austin.ibm.com:636 [Root exception is javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative names present]' naming exception occurred during processing.
