Symptoms

In the atlassian-user.xml, for the <securityAuthentication> element, does Confluence support "DIGEST-MD5", rather than "simple"?

Resolution

Confluence does not support the DIGEST-MD5 in our atlassian-user.xml file. If you set as DIGEST-MD5, then the following properties will also need to be set.

java.naming.security.sasl.authorizationId
java.naming.security.sasl.realm
javax.security.sasl.qop
javax.security.sasl.strength
javax.security.sasl.server.authentication
javax.security.sasl.maxbuffer
javax.security.sasl.policy.noplaintext
javax.security.sasl.policy.noactive
javax.security.sasl.policy.nodictionary
javax.security.sasl.policy.noanonymous
javax.security.sasl.policy.forward
javax.security.sasl.policy.credentials

These parameters could potentially be passed as properties to the JVM startup (setenv.sh/bat): -

Confluence code does NOT read these properties in the xml file, so this workaround should work theoretically, though Atlassian has not officially tested this configuration.
