Hopefully folks can help point me in the right direction so I can figure it out. I figured it out in Miniorange, but need it working in Gluu instead. Desired: Pre-created custom user attribute in Gluu, "discordUid" is auto-filled from Discord User_id during User OAuth/Passport Authentication between Gluu 3.1.6 and Discord. Steps: User lands on the Gluu login page. The page includes the External Providers option with a Passport option to login with Discord (working). User clicks that Discord link, authorizes the Gluu 3.1.6, and user is logged into both Gluu and Discord (working). While doing that authorization process, Gluu user attribute (already created on the server), is populated with the Discord unique username id. (not working in Gluu - did get working in miniorange for learning, but need to get this working directly between Gluu and Discord without the miniorange middle-ware). I already created custom user attribute discordUid on the server. It is text and blank by default. The goal is that any user that goes through the Discord Authentication has that field populated with their unique discord user_id username id number, as per here: https://discord.com/developers/docs/reference . When working, such as in Miniorange, it looks like this: 720923259763425320 (normal username is email, and in discord chatrooms looks like: tfndiscordtest1#3093 This is using Gluu 3.1.6 on Ubuntu 16.04 LTS. In Gluu 4 I see easy attribute mapping in the web UI, but I'm having trouble finding documentation to explain how I should do attribute mapping of (Discord ID) id > discordUid (manually created Gluu user attribute). Could someone point me to the correct resource to do this with 3.1.6? (or else provide a quick pointer here on the process for doing this. Thanks! In mini-orange there is Attribute mapping feature: miniOrange OAuth > Edit Application > Attribute Mapping > Map Custom Attributes > id -> discordUid For miniorange middleware example: https://wp.rpgr.org/logoutlanding1/ click on Gluu316WpDiscordUid1 link is: https://devau.thefantasy.network/oxauth/authorize.htm?scope=openid+email+profile+permission+user_name+discordUid&response_type=code&redirect_uri=https%3A%2F%2Fwp.rpgr.org&state=eyI2MTcwNzA2ZTYxNmQ2NSI6eyJWIjoiNDc2Yzc1NzUzMzMxMzY1NzcwNDQ2OTczNjM2ZjcyNjQ1NTY5NjQzMSIsIkgiOiJhMTU5MWVlN2Y1M2NmYThhNGEzYjM5MTNiNTk3ZjRlOSJ9LCI3MjY1NjQ2OTcyNjU2Mzc0NWY3NTcyNjkiOnsiViI6IjY4NzQ3NDcwNzMzYTJmMmY3NzcwMmU3MjcwNjc3MjJlNmY3MjY3IiwiSCI6Ijc0MDhlYTVmNThjNzJhYjI1YTMzM2RiNzBhZDE0OTIwIn0sIjc1Njk2NCI6eyJWIjoiNDQ0NjM4NTY0YjRhNGYzNTQ2NDQ0ODVhNDE1MjQyNTIzNTVhNDQ1MzMyNTYzNTRhMzYzNjU1MzI0ZTQ0NTIiLCJIIjoiOGE1NzlkN2M4NGM5ODRkNWE4MGY0YzZiOGYwZDQ2OWMifX0%3D&client_id=%40%21DA50.1A15.0388.CAC8%210001%21A8D0.2AEA%210008%21A54A.1776.3AA0.591F Fields in "Test Configuration" result: Test Configuration Attribute Name Attribute Value id 713172580369956965 username tfndiscordtest1 avatar discriminator 3093 public_flags 0 flags 0 email discordtest1@rpgr.org verified locale en-US mfa_enabled OAuth Permission Dialog example: Request for Permission Gluu316WpDiscordUid1 is requesting permission to do the following: * Discord User ID * Authenticate using OpenID Connect. * View your local username in the Gluu Server. * View your email address. If I go to Open ID Connect > Scopes. I see where I can create a custom scope. For this interaction between Discord and Gluu, should I set the Scope Type to OAuth or OpenID? I set to OpenID for now. Should I allow for dynamic registration? For now I set to False. Display name: discorduid. iNum: @!DA50.1A15.0388.CAC8!0001!A8D0.2AEA!0009!658A.E018 Not sure what I am supposed to do with the "add claim" will look for docs about that. Left blank for now. Or should I be doing all of this through customization manually of the discord.js passport file? Thanks for any guidance! EDIT: I found this: https://gluu.org/docs/gluu-server/3.1.6/admin-guide/openid-connect/#customizing-scopes and set claim to find discordUid attribute. Is that on the right track? https://discord.com/developers/docs/resources/user#user-object
