Azure Ad LDAP Authentication
You set up azure ad ldap authentication by deploying Microsoft Entra Domain Services in your cloud network. This managed service lets legacy apps and databases check user logins against your cloud directory. Many engineering teams use this method when old tools cannot use modern web login flows. Still, mapping broad directory groups to database roles often gives users too much power. One shared group role can let an engineer read or delete sensitive production tables.

How azure ad ldap authentication works in your cloud
Standard cloud directories speak modern web protocols rather than legacy directory protocols. They do not accept raw directory bind requests from old apps or database servers. To bridge this gap, you deploy a managed domain service inside your virtual network. This service runs managed domain controllers that stay in sync with your main cloud directory.
Your cloud directory pushes user accounts, group memberships, and password hashes to these managed controllers. The sync runs one way from your central cloud directory to the managed domain. Next, you set up a virtual network link between your database servers and the domain controllers. For traffic outside the private network, you add a digital certificate to turn on encrypted directory traffic. Once the link is live, your database or legacy app sends a bind request to verify a user.
The managed controller checks the password hash and returns the user group list. The target server then matches that group list to its own internal permission roles. This flow lets teams keep one central password for both web apps and legacy servers.
Why directory bind checks do not control live sessions
Setting up a managed directory solves the initial login problem for older servers and databases. When a person leaves the company, you disable one cloud account to block their login. You also stop storing plain local passwords on ten different database servers. Still, directory bind checks only happen at the start of a session.
Once the directory says yes, the database or server takes over for the rest of the session. The directory has no idea what queries or commands the user runs next. Most teams map an entire engineering group to a single read or write role on the database. Everyone in that group gets the exact same permissions all day long.
A developer fixing a small bug can still run a broad query on customer tables. The directory check will not stop a bad drop table statement or a huge data export. It also cannot rewrite sensitive fields like emails, phone numbers, card numbers, or national IDs in query results. Also, directory logs only show that a login took place at a certain time. They never record the actual commands or SQL statements that ran during that session.

Managing network exposure and password sync limits
Running managed domain controllers also adds network and account rules that teams must watch closely. First, legacy directory checks need password hashes stored in a format that supports old protocols. For cloud users, you often must make them reset their passwords before the new hashes sync over. Until a user resets their password, their legacy login requests will fail with bad password errors.
Second, exposing encrypted directory ports to the public internet draws constant brute force attacks. Security teams should restrict directory traffic to private virtual networks and peered cloud networks instead. Even on a private network, service accounts for legacy apps often use long-lived passwords that rarely change. If an attacker steals a service account key, they can query the directory and map your groups. Pairing directory checks with strict runtime controls keeps a single login from turning into full data exposure.
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 sits inline in the wire protocol beside those services as an open-source proxy, a sidecar for your Postgres or API. On every query an AI agent or engineer runs against production, hoop.dev decides to pass, mask, block, or hold it for human review.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run, and hoop.dev data masking rewrites matched sensitive values in responses 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 our standard cloud directory handle LDAP requests directly?
No, the base cloud directory only supports modern web login protocols. You must deploy a managed domain service or run your own domain controllers to accept LDAP requests.
Why do logins fail right after we turn on the managed domain?
The cloud directory does not store the required password hashes for existing users by default. Users must change their passwords once so the cloud directory can generate and sync the right hashes.
Does LDAP login log the queries a user runs on a database?
No, the directory only checks the user password and group membership when the session starts. It does not inspect, log, or block any database queries or server commands after login.
Short role checks help teams work fast. Simple rules make each review clear. Good logs keep every team safe. Scoped keys stop bad changes early.
