OIDC Position
To set up your oidc position, place OpenID Connect at the login step. Your app reads user claims from an identity token and maps them to roles. Most teams link their directory groups straight to broad admin roles. When those roles are too wide, one login gives total control over data. A single bad query or script can then change or drop key tables. How the oidc position works in your login flow OpenID Connect sits on top of the OAuth 2.0 flow to prove user identity.

To set up your oidc position, place OpenID Connect at the login step. Your app reads user claims from an identity token and maps them to roles. Most teams link their directory groups straight to broad admin roles. When those roles are too wide, one login gives total control over data. A single bad query or script can then change or drop key tables.
How the oidc position works in your login flow
OpenID Connect sits on top of the OAuth 2.0 flow to prove user identity. When a person logs in, the identity provider checks their password and second factor. It then builds a signed JSON token that holds user details and group claims. Your app checks the digital signature against the public keys from the provider. This step proves that the token is real and has not expired yet.
Next, the target system reads the claims inside the token to pick a role. For example, a database or cloud console matches a group claim to a local role. The role holds a fixed list of permissions for tables, views, or servers. Once this match finishes, the user starts a live session with those exact rights. The identity provider steps out of the path until the token needs a refresh.
Why role mapping alone leaves a gap
Placing OpenID Connect at the front door solves the problem of shared static passwords. You can turn off a user account in one place to block new logins. You also get a clear log of who logged in and when they started. This setup works well for basic entry control across web apps and cloud tools.
Still, the login check only decides who gets in at the start. It does not inspect the actual commands or SQL statements that run next. If an engineer maps to a write role, every query in that session runs free. The token cannot block a mass delete or a full table read by itself. It also cannot rewrite sensitive fields like emails, phone numbers, or card numbers in results.

Mapping claims to smaller roles
To cut down risk, teams break giant admin roles into smaller task roles. You can set up separate group claims for read tasks and write tasks. You can also set short token lifetimes so sessions must renew more often. These steps shrink the window of time a broad role stays active.
Even with smaller roles, teams still need visibility into live commands and queries. Auditors often ask what data a user read during a specific support ticket. Identity logs only show the token grant, not the rows returned by a query. Closing that gap requires inspecting each command and masking sensitive fields like national IDs.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
What is the difference between OIDC and OAuth 2.0?
OAuth 2.0 grants an app permission to act on a resource using tokens. OpenID Connect adds a standard identity layer so apps know who the user is.
Do OIDC tokens control what queries a user can run?
No, the token only proves identity and passes group claims at login time. The target database or server uses its own local roles to allow or block queries.
How often should an identity token expire?
Short lifetimes of fifteen to sixty minutes work best for most internal tools. When the token expires, the client checks with the identity provider to get a fresh one.
