#summary S2S authentication using DANE
#labels Stage-Alpha, Type-S2SAuth

= Introduction =

This module implements DANE as described in 
[http://tools.ietf.org/html/draft-miller-xmpp-dnssec-prooftype Using DNS Security Extensions (DNSSEC) and DNS-based Authentication of Named Entities (DANE) as a Prooftype for XMPP Domain Name Associations].

= Dependecies =

This module requires a DNSSEC aware DNS resolver.  Prosodys internal DNS 
module does not support DNSSEC.  Therefore, to use this module, a 
replacement is needed, such as
[http://code.zash.se/luaunbound this libunbound and LuaJIT FFI based one].

= Configuration =

This module has no options.  Just add it to `modules_enabled`;
