T. Finch: AUTHOR [+2]
The base DNS-Based Authentication of Named Entities (DANE) specification [RFC6698] describes how to use TLSA resource records secured by DNSSEC [RFC4033] to associate a target server's connection endpoint with its Transport Layer Security (TLS) certificate (thus enabling administrators of domain names to specify the keys used in that domain's TLS servers). Some application protocols locate connection endpoints indirectly via SRV records [RFC2782]. As a result of this indirection, the rules specified in [RFC6698] cannot be directly applied to such application protocols. (Rules for SMTP [RFC5321], which uses MX resource records instead of SRV records, are described in [RFC7672].)

Using DNS-Based Authentication of Named Entities (DANE) TLSA Records with SRV Records
The DNS-Based Authentication of Named Entities (DANE) specification (RFC 6698) describes how to use TLSA resource records secured by DNSSEC (RFC 4033) to associate a server's connection endpoint with its Transport Layer Security (TLS) certificate (thus enabling administrators of domain names to specify the keys used in that domain's TLS servers). However, application protocols that use SRV records (RFC 2782) to indirectly name the target server connection endpoints for a service domain name cannot apply the rules from RFC 6698. Therefore, this document provides guidelines that enable such protocols to locate and use TLSA records.
