Find where authentication actually failed.

Upload authentication evidence from identity providers, RADIUS servers, applications and directories. AuthDoctor correlates the events, identifies the likely failure stage and shows exactly what supports the conclusion.

Analyze a case See supported protocols

Public beta. The core diagnosis is deterministic and tied to observable evidence.

Likely stage: post-authentication application / authorization handling

Next: inspect VPN/NAS logs and returned authorization attributes.

What the prototype does

A specialized authentication diagnostic engine rather than a generic log summarizer.

Correlates attempts

Separates retries and users, using transaction identifiers, usernames and timestamps.

Validates protocols

Recognizes deterministic failures across SAML, OIDC/OAuth, RADIUS, LDAP/AD, Kerberos and WebAuthn.

Shows evidence

Conclusions include source files, lines, facts, confidence, warnings and next actions.

How it works

Describe the symptom

Choose the product/protocol and tell AuthDoctor what the user experiences.

Upload evidence

Drop in logs, CSV/JSON exports or SAML XML. The Evidence Advisor tells you what is useful.

Review the diagnosis
