You set up an auth0 ad connector by installing a local agent on your server. This agent links your local user directory to your cloud identity service. Most teams use this setup so staff can log in with one password. Still, teams often map broad directory groups straight to high database roles. When a local group gives admin rights, every user in that group gets full control.

How the auth0 ad connector works in your network

The auth0 ad connector runs as a background service inside your private network. It opens an outbound link from your server to the cloud identity service. Because the link goes out, you do not need to open inbound firewall ports. When a user tries to log in, the cloud service asks the local agent. The agent checks the user name and password against your local directory server. It also reads the groups and roles assigned to that specific user account. Then the agent sends a simple yes or no response back to the cloud. If the check passes, the cloud service creates a token for the user. The user then presents this token to log in to internal tools and databases. Admins often deploy two or more agents on separate servers for backup. If one local server stops working, the second agent handles the login checks.

What directory sync solves and what it misses

Linking your local directory to the cloud solves a real problem for your team. It stops password sprawl and lets you turn off old accounts in one place. When someone leaves the company, you disable their local account once. That person loses login rights to every linked app right away. Still, directory checks only happen at the start of a work session. The identity check decides who gets in the door, not what they do next. Once an engineer logs in to a database or server, the directory steps back. It cannot see the SQL queries or shell commands that run during the session. It also cannot mask sensitive fields like emails, phone numbers, or card numbers in results. If a user runs a bad delete command, directory group rules will not stop it. Teams still need a way to inspect every single query and command in flight.

Why broad directory groups create database risk

Most companies build their local directory groups around job titles and team names. A new developer joins the backend team and gets added to the backend group. To save time, admins map that single group to a shared database role. That shared role often has write and delete rights on production tables. Now every person on the backend team holds full power over live data. If an attacker steals one laptop, they get the same broad database rights. Even without an attacker, a tired engineer can run an unsafe update by mistake. Directory groups are too blunt to manage safe day-to-day work inside production systems. You need fine controls that check each action and rewrite matched PII fields in results. Separating login identity from runtime action checks keeps your production data safe.

Check database and API queries on the wire

Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.

Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.

Frequently asked questions

Does the auth0 ad connector require inbound firewall ports?

No, the agent makes an outbound link from your local server to the cloud. You do not need to open inbound ports on your network firewall.

What happens if the local server running the agent goes down?

Logins will fail if you only run one agent on a single server. You should run the agent on at least two servers so logins stay up.

Can directory groups restrict specific SQL queries or shell commands?

No, directory groups only verify identity and pass role attributes during the login step. They do not inspect or filter the queries and commands a user runs later.
