SSO for MongoDB - OnePAM | SAML/OIDC SSO for MongoDB Database Access

Overview

Why MongoDB Needs Identity-Based Access Control

MongoDB is the leading document database, powering modern applications that require flexible schemas, horizontal scaling, and real-time analytics. MongoDB access typically relies on connection strings containing database credentials — shared across teams, embedded in application configs, and stored in environment variables. OnePAM's database proxy adds SAML/OIDC authentication to MongoDB without changing your database configuration or application code beyond the connection endpoint. The proxy supports the MongoDB wire protocol, works with mongosh, MongoDB Compass, Mongoc drivers, and application connection strings. Every operation is logged with the authenticated user's corporate identity, providing the audit trails that compliance frameworks demand. OnePAM works with self-hosted MongoDB, MongoDB Atlas, AWS DocumentDB, and Azure Cosmos DB for MongoDB.

Database Security Risks

MongoDB Access Security Risks

Without identity-based database access, these risks threaten your data every day.

Shared database credentials across teams and environments

No audit trail for individual query activity

Static passwords stored in config files and environment variables

Inability to revoke access instantly when team members leave

Default port 27017 exposed without identity verification

The Challenge

Database Security Challenges

These are the risks organizations face with traditional database authentication.

Connection String Sprawl

MongoDB connection strings with embedded credentials spread across application configs, environment variables, and CI/CD pipelines. Each copy is a potential breach vector.

No Native SAML/OIDC

MongoDB supports SCRAM, x.509 certificates, and LDAP — but not SAML or OIDC. Enterprise SSO integration requires external proxy infrastructure.

Shared Database Users

Multiple developers using the same MongoDB user account makes it impossible to distinguish who performed which operations in audit logs.

Atlas Credential Management

Managing MongoDB Atlas database users separately from corporate identity creates provisioning delays, orphan accounts, and inconsistent access policies.

No Operation-Level Audit

MongoDB's built-in audit log (Enterprise only) tracks operations by database user — not by corporate identity. Free Community edition lacks audit logging entirely.

Compliance Gaps

Healthcare, financial, and government applications using MongoDB must prove individual accountability for data access. Shared credentials fail this requirement.

Setup Guide

How OnePAM Adds SSO to MongoDB

Step-by-step guide to deploying identity-based database access.

1

Connect via OnePAM Proxy

Point your MongoDB client or application to the OnePAM database proxy. The proxy speaks native MongoDB wire protocol — works with mongosh, Compass, and all MongoDB drivers.

Update your MongoDB connection string to use the proxy endpoint. No code changes beyond the connection URI.

2

Authenticate via Corporate IdP

OnePAM authenticates users via SAML/OIDC with your corporate IdP (Okta, Azure AD, Google Workspace). MFA is enforced based on your IdP policies.

Interactive users authenticate via browser redirect. Applications and services use pre-authenticated service identity tokens.

3

Credential Injection

OnePAM retrieves the appropriate MongoDB credentials from its vault and establishes the database session. Users never handle database passwords or connection strings with credentials.

Access is scoped based on IdP group membership — different groups get different MongoDB roles and database access.

4

Operation Logging with Identity

Every MongoDB operation (find, insert, update, delete, aggregate) is logged with the corporate identity, providing individual accountability for every data access.

Works with MongoDB Community edition — no Enterprise license required for identity-verified audit logging.

Key Benefits

Benefits of SSO for MongoDB

What changes when you deploy identity-based database access.

Individual Accountability

Every MongoDB operation is tied to a corporate identity. Audit logs show who accessed what data, not just which database user was used.

100% identity attribution

Zero Credential Exposure

Connection strings with embedded credentials are replaced by identity-based access. No passwords in config files.

Zero credential exposure

Works Without Enterprise

OnePAM provides identity-verified audit logging for MongoDB Community — no Enterprise license needed for compliance.

No Enterprise required

MFA on Every Connection

Enforce your IdP's MFA policies on every MongoDB connection. No MongoDB-specific authentication plugin needed.

MFA enforced

Instant Deprovisioning

Disable a user in your IdP and MongoDB access stops immediately. No connection string rotation needed.

Instant revocation

Compliance-Ready Audit

Identity-verified operation logs satisfy SOC 2, HIPAA, PCI DSS requirements without MongoDB Enterprise.

Real-World Scenarios

MongoDB SSO Use Cases

Common scenarios where organizations deploy OnePAM Database SSO.

1

Engineering teams accessing MongoDB Atlas clusters with corporate identity instead of shared connection strings

2

HIPAA-compliant healthcare applications needing individual accountability for patient document access

3

Startups on MongoDB Community that need compliance-grade audit logging without upgrading to Enterprise

4

Instant revocation of MongoDB access when employees or contractors leave the organization

5

SOC 2 audits requiring proof of individual database access controls for MongoDB

6

Multi-environment access management across development, staging, and production MongoDB clusters

7

Data analytics teams querying production MongoDB with read-only, time-limited, audited access

8

Microservice architectures where each service needs scoped MongoDB access tied to service identity

Frequently Asked Questions

SSO for MongoDB FAQ

Common questions about Database SSO and query-level auditing.

Does OnePAM work with MongoDB Atlas?

Yes. OnePAM's database proxy connects to MongoDB Atlas clusters just like any MongoDB client. Point the proxy to your Atlas connection string, and OnePAM handles identity-based authentication for all users connecting through it.

Do I need MongoDB Enterprise for audit logging?

No. OnePAM provides identity-verified operation logging at the proxy level — no MongoDB Enterprise license required. This gives you compliance-grade audit trails on MongoDB Community edition.

How does OnePAM handle MongoDB replica sets?

OnePAM supports MongoDB replica set connection strings and handles primary discovery automatically. During failover, the proxy reconnects to the new primary transparently.

Can I control access at the collection level?

Yes. OnePAM can enforce collection-level access policies based on IdP group membership. For example, the 'analytics' group can read from reporting collections while the 'engineering' group has full access.

Does OnePAM support MongoDB change streams?

Yes. OnePAM's proxy supports MongoDB change streams, aggregation pipelines, and all MongoDB operations transparently. The proxy passes through MongoDB-specific features while adding identity context.

What about MongoDB Compass and GUI tools?

OnePAM works with MongoDB Compass, Studio 3T, and any GUI tool that connects via the MongoDB wire protocol. Users authenticate via their IdP when connecting through the proxy.
