Code Issues Releases Wiki Activity

Rework and improve authentication API and internals

Browse source 
Add

- performSaslAnonymousAuthentication()
- performSaslExternalAuthentication(SSLContext)
- addEnabledSaslMechanism(String)
- addEnabledSaslMechanisms(Collection<String>)

to ConnectionConfiguration.Builder.

Instead of providing a special API call for anonymous authentication,
Smack now has a configuration builder method to set anonymous/external
authentication. This also removes a lot of duplicate code within
Smack.

Also move SASLAnonymous into o.j.smack.sasl.core.

Fixes SMACK-629.
