You set up on prem identity verification by linking your local servers to a central directory. The server checks each user login against directory groups before it grants a session. Many teams start by mapping broad group roles to local admin accounts on each machine. When those roles are too wide, one user can run unsafe commands across many servers.
How on prem identity verification works in local setups
Local systems need a reliable way to check who is at the keyboard. Teams usually run a central directory service inside their own data center. Every server and database trusts this central store to check user names and passwords. When an engineer tries to log in, the server asks the directory for a check. The directory checks the user password and looks up a second factor token. If both checks pass, the directory sends back a signed ticket or token. This token lists the groups that the user belongs to right now. The target server reads the group list and matches it to local system roles. For example, a database group might map to a read or write role on disk. A Linux group might map to root privileges on a set of hosts. Admins must keep these group mappings in sync across every local machine they run. If a team adds a new server, they must join it to the directory first. They also need to set up trust keys between the host and the directory.
Why directory checks leave a gap during live sessions
A local directory check solves the basic problem of who can log in. It stops unknown users at the door and keeps password rules in one place. When someone leaves the team, you can disable their account in one single spot. Still, the directory check ends the moment the session starts on the server. The directory decides who logs in, not what commands or queries run next. Once inside a database, a user with a write role can drop a whole table. Once on a host, an admin can read raw files full of user data. Standard directory logs only show that a login took place at a certain time. They do not record the exact SQL statements or shell commands that ran later. They also cannot mask sensitive fields like emails, phone numbers, card numbers, or national IDs. If an engineer queries a customer table, the database returns the raw text as stored. To control live actions, teams need rules that check each command in flight. They also need data masking that rewrites matched fields in results before they leave.
Steps to tighten local role permissions
Start by listing every local server and database that uses shared admin accounts today. Shared passwords make it impossible to tell which person ran a harmful command. Next, break apart large directory groups that grant write access to every machine. Create smaller roles that match specific tasks, such as reading logs or fixing a service. Map those narrow roles to the lowest local privileges needed on each target host. Remove permanent admin rights from daily user accounts so mistakes do not break systems. Require a fresh second factor check whenever someone switches to a higher role. Check your directory logs each week to find old accounts that no longer log in. Delete unused group mappings on your servers so old permissions do not linger around. Finally, test your backup admin accounts to make sure you can log in during outages.

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 happens if the local directory server goes offline?
Most hosts cache recent login tickets for a short period so work can continue. Teams also keep one emergency local account on each server for offline recovery.
How do databases handle central user groups?
The database checks the user login with the central directory and reads their group name. It then links that external group to an internal database role with set table rights.
Can a directory check stop a bad SQL query?
No, a directory only checks who you are when you first open the session. It does not inspect or block the SQL statements you send after you log in.
