To enable azure ad ldap support, you must deploy Microsoft Entra Domain Services. Standard cloud directories do not speak the legacy LDAP protocol on their own. Teams often set up this managed domain so older apps can check user logins. Still, granting broad directory roles lets users run unchecked commands after they log in.
How azure ad ldap support works in the cloud
Standard cloud identity tools use modern web protocols to check who a user is. Many older apps and databases cannot use these modern web login methods. Instead, they need a classic directory tree to look up users and groups. You bridge this gap by turning on a managed domain service in your cloud.
First, you create a managed domain inside your cloud network. This service runs domain controllers that sync accounts from your main cloud directory. Next, you turn on password hash sync so the managed domain can check passwords. You also add a valid TLS certificate to encrypt all directory traffic.
After the sync finishes, your legacy apps can bind to the managed domain. When a user logs into a database, the database asks the domain to check credentials. If the password and group match, the user gets into the system. You can keep this traffic inside your private network or open it over TLS.
Why directory sync is not enough for production control
Setting up a managed directory solves the basic login problem for legacy tools. You keep one central list of users instead of running local domain servers. When someone leaves the team, you disable their account in one central place. That change syncs to the managed domain and blocks future logins.
Still, directory sync only decides who can open a session at the start. Once the login check passes, the directory steps out of the way. It cannot see what queries or commands the user runs inside the database. A user in a broad directory group often gets full write permissions all day.
Shared service accounts for LDAP bind checks create another security risk. Teams often hardcode these bind passwords into app files and server scripts. If an attacker steals a bind key, they can read your whole user list. Even worse, directory logs only show that a login happened at a certain time.

Risks of broad directory groups in database work
Teams usually map one directory group to a single database role. This setup is fast to build, but it gives out too much power. An engineer who needs to read one table gets access to the entire database. They might run a bad update query or read sensitive customer data by mistake.
Directory groups also lack context about what happens inside a live session. They cannot mask sensitive fields like emails, phone numbers, card numbers, or national IDs. When an engineer runs a broad select statement, raw customer records appear on their screen. Data masking rewrites matched fields in results, which a simple directory cannot do.
Auditors also ask for exact records of every query run against production systems. A domain controller log only proves that an engineer logged in on Tuesday morning. It does not show which rows they read or which tables they changed. To protect production data, teams must inspect and control every command in flight.
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
Does standard Microsoft Entra ID support LDAP out of the box?
No, the standard cloud directory only supports modern web login protocols. You must add a managed domain service to get legacy directory protocol features.
Why do passwords fail to work after turning on the managed domain?
The managed domain needs password hashes to check user logins. Cloud users must reset their passwords once so the new hashes can sync over.
Can LDAP groups control which SQL queries a user runs?
No, directory groups only verify identity and assign a starting role at login. They do not inspect, block, or log individual queries during a live database session.
