Original Pull Request: https://github.com/netbirdio/netbird/pull/5363

State: closed
Merged: No

Describe your changes

Add support for seeding an external IdP connector via the IDP_SEED_INFO environment variable when using the Embedded IdP (Dex), enabling automatic migration of existing user IDs to the Dex-encoded format.

How it works:

Self-hosted instance operator sets IDP_SEED_INFO to a base64-encoded JSON connector config (OIDC)
On startup, the connector is upserted into the Dex static connectors list
After initialization, a migration hook iterates all users — any user whose ID cannot be decoded as a Dex user ID is re-encoded with the seeded connector ID and
atomically updated in the database across all referencing tables (personal_access_tokens, peers, user_invites, accounts, etc.) in a single transaction with deferred
foreign key constraints
Already-migrated users (valid Dex-encoded IDs) are skipped

IDP_SEED_INFO example:

{
  "type": "oidc",
  "name": "Zitadel",
  "id": "zitadel",
  "config": {
    "issuer": "https://server.netbird.io/",
    "clientID": "360335580288057352",
    "clientSecret": "<secret>",
    "redirectURI": "https://server.netbird.io/oauth2/callback"
  }
}

Extra changes

This PR includes support for NB_IDP_MIGRATION_DRY_RUN=true which will output in console logs with the planned oldId -> newId for validation, found it useful to verify that the encoded newId properly matched the oldId + the provided IDP id.
I also included a small code path under management/server/user.go:235 which will keep the user name and email updated with what its received from the JWT token.

TODO

Handle migration of IDs for events / deleted_user tables
Write documentation PR
Test with more providers to make sure no ID matching issues are present

**Original Pull Request:** https://github.com/netbirdio/netbird/pull/5363 **State:** closed **Merged:** No --- ## Describe your changes Add support for seeding an external IdP connector via the IDP_SEED_INFO environment variable when using the Embedded IdP (Dex), enabling automatic migration of existing user IDs to the Dex-encoded format. ### How it works: 1. Self-hosted instance operator sets `IDP_SEED_INFO` to a base64-encoded JSON connector config (OIDC) 2. On startup, the connector is upserted into the Dex static connectors list 3. After initialization, a migration hook iterates all users — any user whose ID cannot be decoded as a Dex user ID is re-encoded with the seeded connector ID and atomically updated in the database across all referencing tables (personal_access_tokens, peers, user_invites, accounts, etc.) in a single transaction with deferred foreign key constraints 4. Already-migrated users (valid Dex-encoded IDs) are skipped `IDP_SEED_INFO` example: ``` { "type": "oidc", "name": "Zitadel", "id": "zitadel", "config": { "issuer": "https://server.netbird.io/", "clientID": "360335580288057352", "clientSecret": "<secret>", "redirectURI": "https://server.netbird.io/oauth2/callback" } } ``` ### Extra changes - This PR includes support for `NB_IDP_MIGRATION_DRY_RUN=true` which will output in console logs with the planned `oldId -> newId` for validation, found it useful to verify that the encoded newId properly matched the oldId + the provided IDP id. - I also included a small code path under [management/server/user.go:235](https://github.com/netbirdio/netbird/pull/5363/changes#diff-998d2ca8f48ecbf2d1a259f3851048dacc8f8ae1dfc13c0e69a34e74eaae817aR235) which will keep the user name and email updated with what its received from the JWT token. ## TODO - [x] Handle migration of IDs for events / deleted_user tables - [ ] Write documentation PR - [ ] Test with more providers to make sure no ID matching issues are present ## Issue ticket number and link ## Stack  ### Checklist - [ ] Is it a bug fix - [ ] Is a typo/documentation fix - [x] Is a feature enhancement - [ ] It is a refactor - [x] Created tests that fail without the change (if possible) > By submitting this pull request, you confirm that you have read and agree to the terms of the [Contributor License Agreement](https://github.com/netbirdio/netbird/blob/main/CONTRIBUTOR_LICENSE_AGREEMENT.md). ## Documentation Select exactly one: - [ ] I added/updated documentation for this change - [ ] Documentation is **not needed** for this change (explain why) ### Docs PR URL (required if "docs added" is checked) Paste the PR link from https://github.com/netbirdio/docs here: https://github.com/netbirdio/docs/pull/__
