New "User sync" tab that imports Microsoft 365 / Entra ID users as
WordPress accounts and keeps them up to date:
- Scope: whole tenant or the (nested) members of selected groups,
guests optional, e-mail domain allow-list respected. Existing accounts
are linked by e-mail address.
- Roles: selectable default role plus a group -> role mapping (in
addition to or instead of the default role, first match wins).
Roles of pre-existing accounts are only managed on request.
- Profile: selectable Graph attributes (names, job title, department,
phones, address, language, ...) and the profile photo as avatar.
- Deprovisioning: accounts disabled or deleted in Microsoft 365 (or
removed from the sync groups) are deactivated or deleted; accounts
deactivated by the sync are reactivated automatically. Deactivated
accounts lose every sign-in path and all sessions.
- Safeguards: dry run, safety stop above 20 % (min. 5) deprovisioning,
abort on any Graph error, "deleted" only on a 404 for the object ID,
protected pre-existing administrators and own account, content
reassignment required for deletion, run lock.
- Runs manually, via WP-Cron or `wp m365-login sync [--dry-run]`.
- Users screen column with deactivate/reactivate row actions and a
read-only Microsoft 365 section on the profile screen.
The Graph client gains paging, retry on throttling and user, group
member and photo endpoints. The group picker is now reusable.
Version 1.1.0, German translations (du/Sie), docs and audit addendum.

Adds an "M365 Login" menu entry with a Microsoft-style icon and one
submenu per tab (Connection, Button, Security). The active tab is taken
from the URL, kept in the post-save redirect and highlighted in the
submenu. Notices are printed explicitly because top-level pages do not
include options-head.php. Links, docs and screenshots updated.

Certificate (RFC 7523 client assertion) as an alternative to the client
secret: one-click generation of a 3072-bit RSA key pair with a
self-signed certificate, .cer download (public part only), own PEM
upload with validation, expiry display, encrypted key storage. Both the
authorization code exchange and the Graph client-credentials request
use the selected method. Step-by-step guides for secret, certificate
and the app registration are shown in the settings.
Security audit (docs/security-audit.md) and fixes:
- Multi-tenant mode ignored the unverified email claim: matching now
uses the UPN only, or the email claim when xms_edov is true.
- Login starts are rate limited per client (30 per 10 minutes).
- Optional trusted proxy header for client IPs
(M365_LOGIN_CLIENT_IP_HEADER / filter).

Groups: a Graph-backed picker on the Security tab (search by name or
paste object IDs) stores allowed group IDs. During sign-in membership is
read from the ID token's groups claim when present, otherwise verified
through Microsoft Graph checkMemberGroups (transitive). Verification
failures refuse the sign-in.
Button-only mode: hides the password form and the lost-password link
and rejects password sign-ins on wp-login.php via the authenticate
filter. A generated, rate-limited fallback key re-enables the form for
30 minutes per browser; M365_LOGIN_DISABLE_BUTTON_ONLY switches the
mode off from wp-config.php.
Also: new German-language README with sequence diagram, settings
reference, troubleshooting and hook examples; readme.txt external
services section now covers Microsoft Graph; translations updated.

Adds a WordPress plugin that places a customisable "Sign in with
Microsoft" button on wp-login.php and signs existing users in via the
OpenID Connect authorization code flow with PKCE. Users are matched by
e-mail address only; no accounts are created.
Security: single-use state/nonce bound to an HttpOnly cookie, ID token
signature verification against Microsoft's JWKS (RS256 only) with
issuer/audience/tenant/expiry/nonce checks, optional tenant pinning,
account binding to the Microsoft object ID, e-mail domain allow-list,
client secret encrypted at rest (AES-256-GCM).
Admin: settings screen with connection, button and security tabs, live
button preview, colour presets, media-library icon picker, redirect URI
copy button and tenant connectivity test.
Packaging for WordPress.org: readme.txt with External services section,
GPL-2.0 license, uninstall.php, POT + German translations, .distignore,
build script, PHPCS config and CI running Plugin Check.
