Multi-platform LDAP
You set up multi platform ldap by linking a central directory to your servers and databases. Each target maps directory groups to local roles so users log in with one password. Teams often build this to stop making local accounts on every Linux, Windows, and database host. When group mappings are too broad, users get full admin rights across every linked system.

You set up multi platform ldap by linking a central directory to your servers and databases. Each target maps directory groups to local roles so users log in with one password. Teams often build this to stop making local accounts on every Linux, Windows, and database host. When group mappings are too broad, users get full admin rights across every linked system.
How multi platform ldap works across systems
A central directory stores user accounts, passwords, and group names in a tree structure. Linux servers, Windows machines, and database engines can all read from this same tree. When an engineer tries to log in, the target host asks the directory to check the password. The host also asks which groups the user belongs to right now.
Each system uses a client tool to talk to the central directory server over the network. On Linux hosts, background services pull user IDs and group names from the directory tree. Database engines like PostgreSQL and MySQL also support directory login checks out of the box. You map a directory group to an internal database role or a local server group.
To keep traffic safe, admins wrap directory checks in encrypted transport layers using server certificates. You also need service accounts so each database or server can search the directory tree. If you run mixed systems, you must match attribute names across Windows and Linux schemas. Once those attributes line up, one directory account works across your whole fleet.
What directory login solves and what it leaves open
Central directory setup solves account sprawl across your fleet of servers and databases. When a person leaves the team, you disable one directory profile to block future logins. You do not need to log in to fifty hosts to delete old local accounts. Password rules and lockouts stay in one place for every linked system.
Still, directory integration only checks who can log in at the start of a session. Once the server or database lets the user in, the directory steps out of the way. It cannot see which queries an engineer runs or which shell commands they type. If a mapped role allows table drops, any user in that group can drop tables.

Shared database roles also make audit logs hard to read during a security review. Ten engineers in the same directory group often map to one shared database admin role. The database log shows the shared role name, not the specific person who ran the query. Also, exposed phone numbers, emails, and card numbers return in plain text to every group member.
Managing group drift and network links
Keeping directory mappings clean across many platforms takes constant work from your ops team. Each database engine and operating system has its own way to link groups to permissions. A change to a group name in the directory can break logins on half your fleet. Admins often fix this by making fewer groups with wider permissions, which increases risk.
Network rules also grow complex when every database and server needs to reach the directory. You must open firewall ports from every subnet back to your central directory servers. If the network link drops, engineers can get locked out of critical hosts during an outage. Caching tools help on Linux, but many database engines require a live directory check every time.
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
Can Linux servers and Windows directories share one setup?
Yes, Linux hosts can read user and group records from a Windows directory server. You set up the Linux client service to map Windows attributes to standard POSIX IDs. Once mapped, engineers log in to Linux shells using their normal Windows passwords.
Does directory login control which SQL queries a user can run?
No, the directory only checks the user password and sends group names during login. The database engine itself decides what the mapped internal role can read or write. The directory cannot pause a risky query or mask card numbers and emails in results.
What happens to open sessions when I disable a directory user?
Disabling a user in the directory only stops new login attempts from succeeding. Any database sessions or server shells that are already open stay active until they close. You must kill active sessions on the target host to cut off a user right away.
