Summary by CodeRabbit

• Behavior Changes
  • OAuth PAR requests now expire after 90 seconds by default. Positive expiry values explicitly configured by operators remain unchanged.
  • CAPTCHA verification fails when no validator is configured, rather than accepting tokens without validation.
  • Client claim validation rejects duplicate claims.
  • Missing, blank, or non-text KBI credentials now produce a field-specific client error.

Walkthrough

The changes set the default OAuth PAR expiry to 90 seconds, reject duplicate client claims, reject CAPTCHA verification when no validator is configured, and return field-specific client errors for invalid KBI credentials.

Changes

PAR expiry default

Layer / File(s)	Summary
Set the PAR expiry default esignet-service/data/deployment.yaml, esignet-service/internal/config/app.go, esignet-service/internal/config/app_test.go	The deployment value and application fallback change to 90 seconds. The test for an unset value expects 90 seconds. Positive configured values remain unchanged.

Client claim validation

Layer / File(s)	Summary
Reject duplicate claims esignet-service/internal/clientmgmt/validate.go, esignet-service/internal/clientmgmt/validate_test.go	validateClaims now returns invalid_claim when claim values contain duplicates. Tests cover adjacent and non-adjacent duplicates and distinct claims.

CAPTCHA validation

Layer / File(s)	Summary
Reject tokens without a validator esignet-service/internal/engine/captcha_provider.go, esignet-service/internal/engine/captcha_provider_test.go	When the validator URL is unset, verification returns Success: false. The warning and test reflect this behavior.

KBI credential errors

Layer / File(s)	Summary
Return field-specific credential errors esignet-service/internal/engine/sunbird/authenticator.go, esignet-service/internal/engine/sunbird/authenticator_test.go	When a KBI credential is absent, not a string, or blank after trimming, authentication returns a client error with code AUTHN-MGR-1008 and a field-specific message. Tests cover missing, empty, and whitespace-only values.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Possibly related issues

• mosip/esignet#2539: The issue tracks duplicate user claims, request URI lifetime, empty KBI inputs, and CAPTCHA token validation. This PR addresses the corresponding duplicate-claim, PAR expiry, KBI input, and CAPTCHA behaviors.

Suggested reviewers: anushasunkada

Merge Risk: Low · previous review e9623

The changes are mergeable with a documentation correction: operators are still told PAR request URIs last an hour rather than 90 seconds. The previously incompatible credential tests have been updated.

Cover a missing fullName case with dob present.

The changed subtest omits dob only. Its Contains "dob" check also passes for any message that names dob, including a hard-coded one. No other test omits fullName, so that regression is not caught elsewhere. The new subtest fails if the error for a missing fullName names dob.

 		p := newTestProvider("http://unused", "http://unused")
 		identifiers := map[string]interface{}{sunbirdIndividualIDKey: "POL123"}

Assert Type in the blank dob subtests.

The empty-value and whitespace-only dob subtests check only Code and Error.DefaultValue. A change that sets a different Type on this branch still passes both subtests. Production sets common.ClientErrorType here, so each subtest should assert it. The test file does not import the common package. Add the same import that authenticator.go uses.
