Keeping OpenID Connect Manpages Up to Date

The command prompt stared back, waiting. You type man oidc and realize the manpage is two years out of date. OpenID Connect (OIDC) has moved fast. Your deployment scripts haven’t. The gap is costing you time.

OIDC is a thin identity layer on top of OAuth 2.0. It lets clients verify the identity of end-users based on authentication by an Authorization Server. It also lets them obtain the end-user’s profile information in a REST-friendly way. Manpages for OIDC commands, tools, and libraries give you the syntax, flags, and expected behavior right from the terminal. But if you rely only on bundled manpages, you’ll miss security updates, new endpoints, and changes that affect token lifecycles.

Modern OIDC manpages cover core commands like oidc-agent, oidc-gen, and oidc-token. They describe how to register clients, configure scopes, handle the authorization code flow, and refresh tokens without breaking sessions. A complete manpage should list environment variables like OIDC_SOCK for agent communication and OIDC_CONFIG_DIR for custom storage paths. It should document exit statuses for automated scripts and detail JSON output fields for machine-readable parsing.

For engineers working with manpages and OpenID Connect, version mismatches are a common failure point. Older manpages may omit PKCE parameters, dynamic client registration details, or updated discovery endpoints. Keeping the manpages aligned with the latest OIDC spec avoids authentication errors and broken integrations. You can generate up-to-date manpages by rebuilding from the source repo of your chosen oidc-agent implementation or using package managers with rolling updates enabled.

OIDC in production is a chain of moving parts: discovery documents, token endpoints, JWKS for signature verification, and session management hooks. The manpages act as the local, offline reference for all of these. They must show command examples for both interactive and non-interactive flows. They must map directly to the Authorization Server’s capabilities so that test and prod environments behave the same.

If your CLI tools are missing flags or producing unexpected token claims, check the manpages first. They are the ground truth for syntax. Then compare them against official OIDC documentation and specs. Updating manpages is more than housekeeping—it is a direct method of reducing downtime and authentication bugs.

Manpages for OpenID Connect are not static manuals. They are living documents that mirror the evolving identity protocol. Keep them current. Integrate them into your onboarding for new team members. Automate their updates alongside package upgrades.
