lua-resty-openidc is a library for NGINX implementing the OpenID Connect Relying Party (RP) and/or the OAuth 2.0 Resource Server (RS) functionality.
When used as an OpenID Connect Relying Party it authenticates users against an OpenID Connect Provider using OpenID Connect Discovery and the Basic Client Profile (i.e. the Authorization Code flow). When used as an OAuth 2.0 Resource Server it can validate OAuth 2.0 Bearer Access Tokens against an Authorization Server or, in case a JSON Web Token is used for an Access Token, verification can happen against a pre-configured secret/key .
It maintains sessions for authenticated users by leveraging lua-resty-session thus offering
a configurable choice between storing the session state in a client-side browser cookie or use
in of the server-side storage mechanisms shared-memory|memcache|redis.
It supports server-wide caching of resolved Discovery documents and validated Access Tokens.
It can be used as a reverse proxy terminating OAuth/OpenID Connect in front of an origin server so that the origin server/services can be protected with the relevant standards without implementing those on the server itself.
lua-resty-openidc depends on the following packages:
The dependencies above come automatically with OpenResty. You will need to install two extra pure-Lua dependencies that implement session management and HTTP client functions:
Typically - when running as an OpenID Connect RP or an OAuth 2.0 server that consumes JWT access tokens - you'll also need to install the following dependency:
The lua-resty-jwt dependency above is not required when running as an OAuth 2.0 Resource Server (only) using remote
introspection for access token validation.
Using luarocks execute the following:
luarocks install lua-resty-openidc
Otherwise copy openidc.lua somewhere in your lua_package_path under a directory named resty.
If you are using OpenResty, the default location would be /usr/local/openresty/lualib/resty.
Older versions of lua-resty-openidc could also be installed using opm but this is no longer supported.

}The so called redirect_uri is an URI that is part of the OpenID
Connect protocoll. The redirect URI is registered with your OpenID
Connect provider and is the URI your provider will redirect the users
to after successful login. This URI then is handelled by
lua-resty-openidc where it obtains tokens and performs some checks and
only after that the browser is redirected to where your user wanted to
go initially.
The redirect_uri is not expected to be handelled by your appication
code at all. It must be an URI wthat lua-resty-openidc is responsible
for so it must be in a location protected by lua-resty-openidc.
You configure the redirect_uri on the lua-resty-openidc side via the
opts.redirect_uri parameter (which defaults to /redirect_uri). If
it starts with a / then lua-resty-openidc will prepend the protocoll
and current hostname to it when sending the URI to the OpenID Connect
provider (taking Forwarded and X-Forwarded-* HTTP headers into
account). But you can also specify an absolute URI containing host and
protocoll yourself.
Before version 1.6.1 opts.redirect_uri_path has been the way to
configure the redirect_uri without any option to take control over
the protocoll and host parts.
Whenever lua-resty-openidc "sees" a local path navigated that matches
the path of opts.redirect_uri (or opts.redirect_uri_path) it will
intercept the request and handle it itself.
This works for most cases but sometimes the externally visible
redirect_uri has a different path than the one locally visible to
the server. This may happen if a reverse proxy in front of your server
rewrites URIs before forwarding the requests. Therefore version 1.7.6
introduced a new option opts.local_redirect_uri_path. If it is set
lua-resty-opendic will intercepts requests to this path rather than
the path of opts.redirect_uri.
-- check session, but do not redirect to auth if not already logged in
local res, err = require("resty.openidc").authenticate(opts, nil, "pass")-- check session, do not redirect to auth if not already logged in but return an error instead
local res, err = require("resty.openidc").authenticate(opts, nil, "deny")The authenticate function returns the current session object as its
forth return argument. If you have configured lua-resty-session to use
a server side storage backend that uses locking, the session may still
be locked when it is returned. In this case you may want to close it
explicitly
local res, err, target, session = require("resty.openidc").authenticate(opts)
session:close()lua-resty-openidc can use shared memory
caches
for several things. If you want it to use the caches, you must use
lua_shared_dict in your nginx.conf file.
Currently up to four caches are used
- the cache named
discoverystores the OpenID Connect Disovery metadata of your OpenID Connect Provider. Cache items expire after 24 hours unless overriden byopts.discovery_expires_in(a value given in seconds) . This cache will store one item per issuer URI and you can look up the discovery document yourself to get an estimate for the size required - usually a few kB per OpenID Connect Provider. - the cache named
jwksstores the key material of your OpenID Connect Provider if it is provided via the JWKS endpoint. Cache items expire after 24 hours unless overriden byopts.jwks_expires_in. This cache will store one item per JWKS URI and you can look up the jwks yourself to get an estimate for the size required - usually a few kB per OpenID Connect Provider. - the cache named
introspectionstores the result of OAuth2 token introspection. Cache items expire when the corresponding token expires. Tokens with unknown expiry are not cached at all. This cache will contain one entry per introspected access token - usually this will be a few kB per token. - the cache named
jwt_verificationstores the result of JWT verification. Cache items expire when the corresponding token expires. Tokens with unknown expiry are not cached for two minutes. This cache will contain one entry per verified JWT - usually this will be a few kB per token.
Note the jwt_verification and introspection caches are shared
between all configured locations. If you are using locations with
different opts configuration the shared cache may allow a token that
is valid for only one location to be accepted by another if it is read
from the cache. In order to avoid cache confusion it is recommended to
set opts.cache_segment to unique strings for each set of related
locations.
The revoke_tokens(opts, session) function revokes the current refresh and access token. In contrast to a full logout, the session cookie will not be destroyed and the endsession endpoint will not be called. The function returns true if both tokens were revoked successfully. This function might be helpful in scenarios where you want to destroy/remove a session from the server side.
With revoke_token(opts, token_type_hint, token) it is also possible to revoke a specific token. token_type_hint can usually be refresh_token or access_token.
