feat(oauth2): set the role of OAuth2 users from an identity provider claim - #10764
Set the pgAdmin role of OAuth2 users from a claim of the identity provider, so administrators can be managed in the IdP instead of being promoted by hand after their first login.
Two new per-provider keys in OAUTH2_CONFIG, following the OAUTH2_SERVER_GROUP_CLAIM / OAUTH2_SERVER_GROUP_CLAIM_MAPPING pair:
OAUTH2_ROLE_CLAIM: the claim to read, from the ID token first, then from the userinfo response.
OAUTH2_ROLE_CLAIM_MAPPING: a dict mapping claim values to pgAdmin role names. The first entry whose value is in the claim gives the role, so more privileged roles are listed first. If no entry matches, or the claim is missing, the user gets the User role.
_resolve_role_from_claims() resolves the role name after the login has been authorised (after the OAUTH2_ADDITIONAL_CLAIMS check). It returns None when OAUTH2_ROLE_CLAIM is not set, and logs a warning and returns None when the mapping is missing or empty. Non-string claim values are ignored.
_sync_user_role() runs on every login, after OAUTH2_AUTO_CREATE_USER has created the user if needed. It replaces the user's role with the resolved one and commits only when the role differs. If the mapped role does not exist, it logs a warning and leaves the role unchanged.
get_user_profile() fetches userinfo when the role claim is not in the ID token, as it already does for the username, additional and server group claims.
Because the role is synced at each login, removing a user from the IdP group also removes the role at their next login. A role changed in the user management dialog is overwritten at the next login; this is documented. Users who log in by other methods are not affected.
The role claim does not decide who may log in: it is applied only after the OAUTH2_ADDITIONAL_CLAIMS check, so a user in none of the expected groups is still refused and not created. Giving unmatched users User is the same role OAUTH2_AUTO_CREATE_USER gives today.
Tests
New scenarios in web/pgadmin/browser/tests/test_oauth2_with_mocking.py:
mapped role from the ID token, from a single string claim and from userinfo;
no match gives User;
the first mapping entry wins when several match;
a mapped role that does not exist leaves the role unchanged;
a user who loses the claim value is given User at the next login;
a user refused by OAUTH2_ADDITIONAL_CLAIMS is not created;
get_user_profile() fetches userinfo for the role claim.
python regression/runtests.py --pkg browser.tests --modules test_oauth2_with_mocking passes (40 tests) against PostgreSQL 18. Without the change in oauth2.py, 6 of the new tests fail. pycodestyle --config=.pycodestyle passes on the changed files.
Backwards compatibility
Opt-in. When OAUTH2_ROLE_CLAIM is not set, behaviour is unchanged.
Notes
I did not add a release note entry, since release_notes_9_20.rst does not exist yet. I'm happy to add one wherever you prefer.
An earlier version of this feature in our deployment was a user_logged_in signal handler in config_local.py that did the same sync. This PR moves it into pgAdmin so it does not depend on internal APIs.
Summary by CodeRabbit
New Features
OAuth2 logins can assign a pgAdmin role based on identity-provider claims. Claim values are matched exactly against configured mappings, with the first match determining the role. Claims are checked in the ID token and then userinfo, and can be a string or a list of strings.
A missing claim or no match assigns the User role. If the mapped role is unavailable, the existing role is unchanged. Role claims do not authorize login, and manual role changes are overwritten at the next login. Other authentication methods are unaffected.
Documentation
Added guidance on configuring role claims and mapping behavior.
OAuth2 configuration now supports mapping identity-provider claims to pgAdmin roles. OIDC login reads the configured claim from the ID token or userinfo and synchronizes the user’s role. Tests cover mapping, userinfo fallback, rejected logins, and later role changes.

Merge Risk: Low · up to ec37d
Role mapping is opt-in, and invalid mapping values no longer break login. If an identity provider omits the role claim, an administrator is demoted to User at the next login, so operators should be aware of this before enabling the feature.

Explanation
Issue #8115 asks for OAuth2 users to gain or lose the Administrator role from identity-provider claims. The PR adds optional per-provider role-claim and mapping settings, resolves claims from the ID token or userinfo, and syncs the selected role at login. An unmatched claim selects User, which supports revoking the role. The reported tests cover role assignment, claim removal, userinfo lookup, and refusal before user creation when authorization claims fail.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
A claim of None and a missing claim both resolve to User, which can demote users when the provider omits the claim.
If the identity provider fails to return the claim (for example, a token without the groups scope), every user, including existing administrators, is demoted to User at that login. The documentation states this behavior. The risk is operational: a misconfigured scope can remove all OAuth2 administrators. Consider leaving the role unchanged when the claim is absent from both the ID token and userinfo. Alternatively, keep the current behavior and ensure the documented warning stays prominent.

The test email is unique and the test DB is recreated on each run, so it covers the first login. Falling back to User when the claim is missing is intentional, same as OAUTH2_SERVER_GROUP_CLAIM: some providers omit the claim when the user has no groups.

Test that invalid mappings preserve an existing role.
Both scenarios assert the first-login User role. They can pass if invalid mappings incorrectly reset an existing Administrator to User. Create an Administrator before login and assert that the role remains unchanged.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Role replacement can leave the pgAdmin instance with no administrator.
_sync_user_role replaces all roles at each login. If the identity provider claim stops matching for the last Administrator, that user loses the role. This can happen after a claim misconfiguration or when the provider omits the claim. The next login then overwrites any role set in pgAdmin.
The PR documents this behavior. It is still a lockout risk, because internal users are not affected but OAuth2 admins are. Consider logging a warning when the change removes the Administrator role, or document a recovery path.

Role downgrade can lock out the last Administrator.
When a claim is missing or unmatched, _resolve_role_from_claims returns 'User'. _sync_user_role then replaces the role of every OAuth2 user, including the last Administrator. If the IdP omits the claim, or the userinfo fetch fails silently, that user loses admin rights at the next login. No guard prevents the removal of the last Administrator.
The behavior is opt-in and the PR documents it. Consider logging a warning, or skipping the downgrade, when the change would remove the last active Administrator.

Summary
Set the pgAdmin role of OAuth2 users from a claim of the identity provider, so administrators can be managed in the IdP instead of being promoted by hand after their first login.
Fixes #8115
What changed
Two new per-provider keys in
OAUTH2_CONFIG, following theOAUTH2_SERVER_GROUP_CLAIM/OAUTH2_SERVER_GROUP_CLAIM_MAPPINGpair:OAUTH2_ROLE_CLAIM: the claim to read, from the ID token first, then from the userinfo response.OAUTH2_ROLE_CLAIM_MAPPING: a dict mapping claim values to pgAdmin role names. The first entry whose value is in the claim gives the role, so more privileged roles are listed first. If no entry matches, or the claim is missing, the user gets theUserrole.How it works
In
web/pgadmin/authenticate/oauth2.py:_resolve_role_from_claims()resolves the role name after the login has been authorised (after theOAUTH2_ADDITIONAL_CLAIMScheck). It returnsNonewhenOAUTH2_ROLE_CLAIMis not set, and logs a warning and returnsNonewhen the mapping is missing or empty. Non-string claim values are ignored._sync_user_role()runs on every login, afterOAUTH2_AUTO_CREATE_USERhas created the user if needed. It replaces the user's role with the resolved one and commits only when the role differs. If the mapped role does not exist, it logs a warning and leaves the role unchanged.get_user_profile()fetches userinfo when the role claim is not in the ID token, as it already does for the username, additional and server group claims.Because the role is synced at each login, removing a user from the IdP group also removes the role at their next login. A role changed in the user management dialog is overwritten at the next login; this is documented. Users who log in by other methods are not affected.
The role claim does not decide who may log in: it is applied only after the
OAUTH2_ADDITIONAL_CLAIMScheck, so a user in none of the expected groups is still refused and not created. Giving unmatched usersUseris the same roleOAUTH2_AUTO_CREATE_USERgives today.Tests
