Can't configure OpenID Connect RP Extra claims in lemonldap web manager
I've successfully configured lemonldap-ng as OpenID Connect Provider, and it seems to work OK.
Now I'm trying to add/configure Extra Claims for the Relaying Party, so in the lemonldap web manager I navigate to:
OpenID Connect Relaying Parties -> rp-example -> Options
Now when I click "Extra claims" the browser gets stuck with "Waiting for datas". I can see the web browser successfully fetches "oidcRPMetaDataOptionsExtraClaims" json from the lemonldap server, but the web interface is still stuck waiting for datas..
I've enabled debug verbose logging in lemonldap manager, but I can't see any errors in httpd error_log.
There are no existing Extra claims configured, because I haven't been able to access the configuration web page yet. So extra-claims wise it's still with default configuration settings/options.
Any tips?
