# Auth Module: PingFederate Provider
2+
3+
This module provides a PingFederate auth provider implementation for `@backstage/plugin-auth-backend`.
4+
5+
The provider uses OIDC authentication and includes PingFederate-specific sign-in resolvers for matching users via LDAP UUID and Ping Identity user IDs.
6+
7+
> **Note:** This provider has only been tested with LDAP catalog provider (`@backstage/plugin-catalog-backend-module-ldap`). It has not been tested with the PingOne catalog provider (`@backstage-community/plugin-catalog-backend-module-pingidentity`), though it should work with appropriate resolver configuration.
8+
9+
## Installation
10+
11+
```bash
12+
yarn add --cwd packages/backend @backstage-community/plugin-auth-backend-module-pingfederate-provider
13+
```
14+
15+
## Configuration
16+
17+
> **Important:** You must configure at least one sign-in resolver. There is no default resolver - the `resolver` field is mandatory.
18+
19+
Add the following to your `app-config.yaml`:
20+
21+
```yaml
22+
auth:
23+
environment: development
24+
providers:
25+
pingfederate:
26+
development:
27+
# Base URL of your PingFederate server (without the .well-known path)
28+
baseUrl: ${PINGFEDERATE_BASE_URL} # e.g., https://your-pingfederate-server.com
29+
clientId: ${PINGFEDERATE_CLIENT_ID}
30+
clientSecret: ${PINGFEDERATE_CLIENT_SECRET}
31+
signIn:
32+
resolvers:
33+
# Resolver is required - choose one that matches your catalog setup:
34+
35+
# Option 1: Match LDAP UUID annotation
36+
- resolver: ldapUuidMatchingAnnotation
37+
ldapUuidKey: 'ldap_uuid' # optional, defaults to 'ldap_uuid'
38+
39+
40+
# Option 2: Match Ping Identity user ID annotation
41+
# - resolver: subClaimMatchingPingIdentityUserId
42+
43+
# Option 3: Match email local part to user entity name
44+
# - resolver: emailLocalPartMatchingUserEntityName
45+
```
46+
47+
### Optional Configuration
48+
49+
You can customize the provider behavior with additional configuration options:
50+
51+
```yaml
52+
auth:
53+
providers:
54+
pingfederate:
55+
development:
56+
baseUrl: ${PINGFEDERATE_BASE_URL}
57+
clientId: ${PINGFEDERATE_CLIENT_ID}
58+
clientSecret: ${PINGFEDERATE_CLIENT_SECRET}
59+
60+
# Optional: Request additional scopes beyond the default openid, profile, email
61+
additionalScopes:
62+
- offline_access
63+
# Or as a single string:
64+
# additionalScopes: offline_access
65+
66+
# Optional: Control the authentication prompt behavior
67+
# 'none' (default) - SSO if session exists, 'login' - force login, 'auto' - let provider decide
68+
prompt: none
69+
70+
# Optional: Override the callback URL if different from the default
71+
# callbackUrl: https://backstage.example.com/api/auth/pingfederate/handler/frame
72+
73+
signIn:
74+
resolvers:
75+
- resolver: ldapUuidMatchingAnnotation
76+
```
77+
78+
## Register the Provider
79+
80+
Add the following to your `packages/backend/src/index.ts`:
81+
82+
```typescript
83+
const backend = createBackend();
84+
backend.add(
85+
import(
86+
'@backstage-community/plugin-auth-backend-module-pingfederate-provider'
87+
),
88+
);
89+
```
90+
91+
## Available Sign-In Resolvers
92+
93+
You must configure at least one resolver in your `app-config.yaml`. Choose the resolver that matches your catalog setup and identity provider configuration.
94+
95+
### PingFederate-Specific Resolvers
96+
97+
- **`ldapUuidMatchingAnnotation`** - Matches an LDAP UUID claim to the `backstage.io/ldap-uuid` annotation
98+
99+
- Configuration options:
100+
- `ldapUuidKey` (optional, default: `'ldap_uuid'`) - The claim name containing the LDAP UUID
101+
- `dangerouslyAllowSignInWithoutUserInCatalog` (optional) - Allow sign-in even if user is not in catalog
102+
- Validates that the UUID in userinfo matches the UUID in the ID token
103+
- **Requires PingFederate LDAP UUID configuration** (see setup instructions below)
104+
105+
- **`subClaimMatchingPingIdentityUserId`** - Matches the `sub` claim to the `pingidentity.org/id` annotation
106+
- Configuration options:
107+
- `dangerouslyAllowSignInWithoutUserInCatalog` (optional) - Allow sign-in even if user is not in catalog
108+
- Best for PingOne catalog provider integration
109+
- Validates that the `sub` claim in userinfo matches the `sub` in the ID token
110+
111+
#### PingFederate Configuration for LDAP UUID Resolver
112+
113+
The `ldapUuidMatchingAnnotation` resolver requires PingFederate to be configured to expose the LDAP UUID attribute. Follow these steps:
114+
115+
**1. Configure Authentication Policy Contract**
116+
117+
1. Create a contract named `rhdh-contract`
118+
2. Add Attribute Source: Link your LDAP Data Store to this contract
119+
3. Set Search Filter: Use `sAMAccountName=${username}` (or appropriate filter for your LDAP)
120+
4. Expose the LDAP UUID attribute under the Authentication Policy Contract Mapping
121+
5. For Active Directory, add the UUID field called `objectGUID` (note: UUID attribute name varies by LDAP vendor)
122+
6. Set Encoding type to `Hex` from the dropdown
123+
7. Enter search filter as needed (e.g., `sAMAccountName=${username}`)
124+
125+
**2. Map UUID to Sub Claim**
126+
127+
Under Contract Fulfillment, map `sub` to the objectGUID from LDAP:
128+
129+
1. From Source dropdown, select `Expression`
130+
2. Enter the following OGNL expression to format the LDAP UUID as expected by Backstage:
131+
132+
```java
133+
#GUID = #this.get("ds.<ldap-data-source-id>.objectGUID").toString(),
134+
#GUID.substring(6,8) + #GUID.substring(4,6) + #GUID.substring(2,4) + #GUID.substring(0,2) + "-" +
135+
#GUID.substring(10,12) + #GUID.substring(8,10) + "-" +
136+
#GUID.substring(14,16) + #GUID.substring(12,14) + "-" +
137+
#GUID.substring(16,20) + "-" + #GUID.substring(20,32)
138+
```
139+
140+
Replace `<ldap-data-source-id>` with your actual LDAP data source ID.
141+
142+
**3. Configure OAuth & OIDC Scopes**
143+
144+
1. Navigate to **System > OAuth Scopes**
145+
2. Ensure `email` and `profile` are added as Common Scopes
146+
147+
**4. Bridge Contract to OIDC Policy**
148+
149+
Use the Access Token as a bridge to ensure the `sub` claim is delivered consistently:
150+
151+
1. **Access Token Mapping**: Create a mapping from `rhdh-contract` to your Access Token Manager. Map the `sub` field from the contract to the token.
152+
2. **OIDC Policy Fulfillment**: In your OIDC Policy, fulfill the `sub` claim by selecting Access Token as the source and `sub` as the value.
153+
3. **Enable Delivery**: In the OIDC Policy Attribute Contract, ensure the ID Token and UserInfo checkboxes are selected for the `sub` claim.
154+
155+
**5. (Optional) Expose UUID under `ldap_uuid` claim in UserInfo**
156+
157+
If you want the UUID available under a custom `ldap_uuid` claim in UserInfo (instead of the default `sub` claim):
158+
159+
1. Under **OIDC Policy Attribute Contract**:
160+
- Extend the contract with `ldap_uuid` under Attribute Contract
161+
- Under Contract Fulfillment, map `ldap_uuid` to the UUID value via Access Token
162+
163+
Then configure your Backstage auth to use:
164+
165+
```yaml
166+
signIn:
167+
resolvers:
168+
- resolver: ldapUuidMatchingAnnotation
169+
ldapUuidKey: 'ldap_uuid' # Custom claim name
170+
```
171+
172+
### Common Resolvers
173+
174+
- **`emailLocalPartMatchingUserEntityName`** - Matches the local part of the email to the user entity name
175+
- Configuration options:
176+
- `allowedDomains` (optional) - Restrict sign-in to specific email domains
177+
- `dangerouslyAllowSignInWithoutUserInCatalog` (optional) - Allow sign-in even if user is not in catalog
178+
- **`emailMatchingUserEntityProfileEmail`** - Matches the email to the user entity's email
179+
- Configuration options:
180+
- `dangerouslyAllowSignInWithoutUserInCatalog` (optional) - Allow sign-in even if user is not in catalog
