$session_secret error

[cyf992002]

Hello,
I am using this plugin to work with keycloak and get following error every time I send a request to the server. Please help.

Hi Tuomo , Thanks for the reply. Yes, I have. Please see my configuration below. I looked into the code and the plugin works well after I commented out '*session.configure(config)*' in handler.lua. Any thoughts? [image: Inline image 2]

When you enable this plugin in kong you should tell client name (client_name_in_oidc_provider) and secret (client_secret_in_oidc_provider), for example curl -i -X POST --url http://localhost:8001/plugins/ --data 'name=<plugin_name>' --data "config.client_id=<client_name_in_oidc_provider>" --data "config.client_secret=<client_secret_in_oidc_provider>" --data "config.discovery=https://<oidc_provider_hostname>/auth/ realms/<realm_name>/.well-known/openid-configuration" — You are receiving this because you authored the thread.

here comes the config

Hi, sorry that I deleted my question.
But it is good that you gave your config because I noticed that we have a bug (there should be no default value, and we have "no").

We have added session_secret because of this
zmartzone/lua-resty-openidc#39

We should correct this (remove default value) and give instructions how to set session_secret (you need also something in ngix configuration).

Could you please tell what Nginx config should I do? and how to set the session secret? Thanks for your help

[tsyrjanen]

In nginx conf-file we have added under

server {
server_name kong;

following line

set_decode_base64 $session_secret 'XX';

In XX we use some decoded default value which kong-oidc will later change.

When enabling oidc plugin you could give also session_secret, for example

curl -i -X POST --url http://localhost:8001/plugins/
--data 'name=<plugin_name>'
--data "config.client_id=<client_name_in_oidc_provider>"
--data "config.client_secret=<client_secret_in_oidc_provider>"
--data "config.discovery=https://<oidc_provider_hostname>/auth/realms/<realm_name>/.well-known/openid-configuration"
--data "config.session_secret=<base64_encoded password>"
