Issue

• Is AES 256 encryption supported with JBoss EAP 5?
• After enabling the kerberos authentication, the following error is observed:-

Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256 CTS mode with HMAC SHA1-96 is not supported/enabled). Encryption type AES256 CTS mode with HMAC SHA1-96 is not supported/enabled"

• Please advise how to set up https connector on EAP6.3.3 on Java 1.7 u76. We currently have following connector as perhttps://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6.3/html/Security_Guide/SSL_Connector_Reference1.html. Cipher TLS_RSA_WITH_AES_256_CBC_SHA doesn’t seem supported.
• Getting JBWEB003043: Error initializing endpoint: java.io.IOException: JBWEB002081: No cipher match when using cipher-suite="TLS_RSA_WITH_AES_256_CBC_SHA".
