Organization-grade identity-fabric mapping: tenant/federation fingerprinting and the pre-auth user-ENUMERATION oracle methodology — enumeration and fingerprint only, never credential submission. Covers domain-to-tenant resolution (Microsoft getuserrealm.srf Managed/Federated namespace check, Entra OIDC metadata tenant-GUID extraction, Autodiscover v2), keyless Microsoft tenant-federation mapping (GetFederationInformation SOAP -> sibling-domain discovery, discover-only ROE, FEDERATED_WITH…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Identity-Provider Recon — Tenant, Federation & User-Enumeration Oracle Mapping > Companion skills: [`osint-methodology`](../osint-methodology/) (§6.2 detectability tagging, §11 > identity-fabric pointer — the "how to think" skill this plugs into) and > [`offensive-osint`](../offensive-osint/) (§22 Identity Fabric — the concrete endpoint/payload > reference this skill builds a workflow on top of, rather than re-listing). This skill answers the > question those two don't: **how do the tenant, its federation partners, its IdP, and its > user-enumeration oracle fit together as one map** — and where exactly enumeration stops and > credential submission begins. ## 0. When to Use / When NOT **Use this skill when:** - You need to resolve a domain to its identity tenant (Entra/Okta/ADFS/Google Workspace) and determine whether auth is Managed or Federated. - You need to map an org's **federation boundary** — every sibling domain that shares the same M365/Azure AD tenant trust, not just the seed. - You need to distinguish Entra vs. Okta vs. ADFS vs. Google Workspace vs. a generic OIDC IdP from passive/low-detectability signals. …

How to install
mdr add elementalsouls/claude-osint/identity-provider-recon@sha256:82c16353ecdb9fd4The line at the top of this page pins the label v1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
