mod_http_oauth2: Add role selector to consent page
List includes all roles available to the user, if more than one.
Defaults to either the first role in the scope string or the users
primary role.
Earlier draft listed all roles, but having options that can't be
selected is bad UX and the entire list of all roles on the server could
be long, and perhaps even sensitive.
Allows e.g. picking a role with fewer permissions than what might
otherwise have been selected.
UX wise, doing this with more checkboxes or possibly radio buttons would
have been confusion and/or looked messier.
Fixes the previous situation where unselecting a role would default to
the primary role, which could be more permissions than requested.

--- labels: - Stage-Broken - Type-S2SAuth summary: S2S authentication using DANE ... Introduction ============ This module implements DANE as described in [Using DNS Security Extensions (DNSSEC) and DNS-based Authentication of Named Entities (DANE) as a Prooftype for XMPP Domain Name Associations](http://tools.ietf.org/html/draft-miller-xmpp-dnssec-prooftype). Dependencies ============ 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 [this one](https://www.zash.se/luaunbound.html). LuaSec 0.5 or later is also required. Configuration ============= After [installing the module][doc:installing\_modules], just add it to `modules_enabled`; modules_enabled = { ... "s2s_auth_dane"; } DANE Uses --------- By default, only DANE uses are enabled. dane_uses = { "DANE-EE", "DANE-TA" } Use flag Description ----------- ------------------------------------------------------------------------------------------------------- `DANE-EE` Most simple use, usually a fingerprint of the full certificate or public key used the service `DANE-TA` Fingerprint of a certificate or public key that has been used to issue the service certificate `PKIX-EE` Like `DANE-EE` but the certificate must also pass normal PKIX trust checks (ie standard certificates) `PKIX-TA` Like `DANE-TA` but must also pass normal PKIX trust checks (ie standard certificates) DNS Setup ========= In order for other services to verify your site using using this plugin, you need to publish TLSA records (and they need to have this plugin). Here's an example using `DANE-EE Cert SHA2-256` for a host named `xmpp.example.com` serving the domain `example.com`. $ORIGIN example.com. ; Your standard SRV record _xmpp-server._tcp.example.com IN SRV 0 0 5269 xmpp.example.com. ; IPv4 and IPv6 addresses xmpp.example.com. IN A 192.0.2.68 xmpp.example.com. IN AAAA 2001:0db8:0000:0000:4441:4e45:544c:5341 ; The DANE TLSA records. _5269._tcp.xmpp.example.com. 300 IN TLSA 3 0 1 E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855 ; If your zone file tooling does not support TLSA records, you can try the raw binary format: _5269._tcp.xmpp.example.com. 300 IN TYPE52 \# 35 030001E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855 [List of DNSSEC and DANE tools](http://www.internetsociety.org/deploy360/dnssec/tools/) Further reading =============== - [DANE Operational Guidance][rfc7671] # Compatibility version status --------- ------------ trunk broken[^1] 0.12 broken 0.11 works 0.10 works 0.9 works **Broken** since [trunk revision 756b8821007a](https://hg.prosody.im/trunk/rev/756b8821007a). # Known issues - A race condition between the DANE lookup and completion of the TLS handshake may cause a crash. This does not happen in **trunk** thanks to better async support. [^1]: since [756b8821007a](https://hg.prosody.im/trunk/rev/756b8821007a)
