Testing: Manually tested with real Feishu OAuth — built-in provider login, custom provider login, dual-provider display, per-provider claim overrides, Admin UI CRUD, slug validation, malformed env var graceful fallback.
Agentic AI Code: Human reviewed and manually tested with real Feishu OAuth flow.
Code review: Self-reviewed, also addressed automated code review findings.

Changelog Entry
Description
Allow administrators to configure multiple custom OAuth/SSO providers at runtime via Admin UI or CUSTOM_OAUTH_PROVIDERS_CONFIG environment variable. This enables use cases like multiple Feishu enterprises, multiple OIDC providers, or any OAuth2-compatible provider — without code changes.
Related PRs #12945 and #18948 focus on Admin UI for existing single-instance OAuth config. This PR specifically addresses the multiple providers of the same type use case.
Added
CUSTOM_OAUTH_PROVIDERS_CONFIG PersistentConfig for dynamic custom OAuth provider storage (supports both env var JSON array and Admin UI)
Admin CRUD API endpoints at /api/v1/auths/admin/config/oauth/custom
"Custom SSO Providers" management section in Admin Settings > General
provider_type field on all providers to generalize type-specific logic
reload_providers() on OAuthManager for hot-reloading after config changes
Dynamic OAuth login button rendering via {#each} loop
Changed
/api/configoauth.providers values from plain strings to objects {name, icon_url, is_custom, provider_type}
Feishu data-unwrap logic generalized via provider_type instead of hardcoded provider name
Built-in providers now include name and provider_type fields
Fixed
Feishu sub_claim from user_id to open_id to match actual Feishu v1 userinfo API response
Security
Client secrets redacted in admin API GET responses
Slug validation prevents conflicts with built-in provider names
GitHub email fetch restricted to built-in github provider only
Malformed env var handled gracefully with fallback
Breaking Changes
BREAKING CHANGE: /api/configoauth.providers response format changed from {key: name_string} to {key: {name, icon_url, is_custom, provider_type}}. Only affects the bundled frontend (updated in this PR).

# Changelog Entry
### Description
Allow administrators to configure **multiple custom OAuth/SSO providers** at runtime via Admin UI or `CUSTOM_OAUTH_PROVIDERS_CONFIG` environment variable. This enables use cases like multiple Feishu enterprises, multiple OIDC providers, or any OAuth2-compatible provider — without code changes.
Related PRs #12945 and #18948 focus on Admin UI for existing single-instance OAuth config. This PR specifically addresses the **multiple providers of the same type** use case.
### Added
- `CUSTOM_OAUTH_PROVIDERS_CONFIG` PersistentConfig for dynamic custom OAuth provider storage (supports both env var JSON array and Admin UI)
- Admin CRUD API endpoints at `/api/v1/auths/admin/config/oauth/custom`
- "Custom SSO Providers" management section in Admin Settings > General
- Per-provider claim overrides: `sub_claim`, `email_claim`, `username_claim`, `picture_claim`, `email_fallback`
- `provider_type` field on all providers to generalize type-specific logic
- `reload_providers()` on OAuthManager for hot-reloading after config changes
- Dynamic OAuth login button rendering via `{#each}` loop
### Changed
- `/api/config` `oauth.providers` values from plain strings to objects `{name, icon_url, is_custom, provider_type}`
- Feishu data-unwrap logic generalized via `provider_type` instead of hardcoded provider name
- Built-in providers now include `name` and `provider_type` fields
### Fixed
- Feishu `sub_claim` from `user_id` to `open_id` to match actual Feishu v1 userinfo API response
### Security
- Client secrets redacted in admin API GET responses
- Slug validation prevents conflicts with built-in provider names
- GitHub email fetch restricted to built-in `github` provider only
- Malformed env var handled gracefully with fallback
### Breaking Changes
- **BREAKING CHANGE**: `/api/config` `oauth.providers` response format changed from `{key: name_string}` to `{key: {name, icon_url, is_custom, provider_type}}`. Only affects the bundled frontend (updated in this PR).

### Configuration Example
```bash
CUSTOM_OAUTH_PROVIDERS_CONFIG='[{
"slug": "feishu-enterprise-b",
"display_name": "Feishu Enterprise B",
"provider_type": "feishu",
"client_id": "cli_xxx",
"client_secret": "xxx",
"authorize_url": "https://accounts.feishu.cn/open-apis/authen/v1/authorize",
"access_token_url": "https://open.feishu.cn/open-apis/authen/v2/oauth/token",
"userinfo_endpoint": "https://open.feishu.cn/open-apis/authen/v1/user_info",
"scope": "contact:user.base:readonly",
"sub_claim": "open_id",
"email_fallback": true,
"enabled": true
}]'
```
No database migration needed.
### Testing Performed
1. Started Open WebUI locally with `FEISHU_CLIENT_ID` + `CUSTOM_OAUTH_PROVIDERS_CONFIG` (two Feishu providers)
2. Verified `/api/config` returns both providers in new object format
3. Login page displayed both "Feishu" and "飞书企业B" buttons
4. Built-in Feishu OAuth login: redirect → authorize → callback → user created successfully
5. Custom feishu-b OAuth: redirect → authorize → callback → correctly detected email conflict (same test account)
6. Unit tests: slug validation (11 cases pass), malformed JSON graceful fallback, provider reload add/remove
