Seamless Integration

Our LDAP Proxy works effortlessly with your current LDAP clients, requiring no modifications to your existing applications or VPNs. There's no need to overhaul your LDAP infrastructure; simply add this effective MFA authentication layer to enhance your security posture with minimal effort.

MFA with Group or Policies

Organizations can enforce authentication requirements dynamically, applying MFA based on user roles, departments, or risk levels. This approach strengthens security, enhances compliance, and streamlines access control without disrupting workflows, making identity management more efficient and tailored to organizational needs.

Seamless Multi-factor Authentication

Go beyond basic username and password verification. Our proxy ensures secure authentication with robust MFA capabilities, supporting a variety of convenient options to suit your organization's needs:

  • miniOrange Push Notification
  • Microsoft Push Notification
  • Email Link Verification
  • SMS Link Verification

Wide Compatibility

The miniOrange LDAP Proxy is built for flexibility. It works seamlessly with your preferred directory services, including:

  • Active Directory (AD)
  • OpenLDAP
  • Google Secure LDAP (supporting certificate-based bindings)

It also fully supports both LDAP and LDAPS communication protocols for broad application.

TLS Encryption for Security

Security is paramount. The proxy ensures all communication between itself and your LDAP server is securely encrypted via TLS. This critical feature significantly reduces the risk of data interception and prevents unauthorized access to your sensitive LDAP traffic.

Lightweight Deployment Model

Getting started is quick and easy. The miniOrange LDAP Proxy is provided as a standalone JAR file, ensuring a stress-free setup. Its lightweight nature allows for rapid integration into your existing IT environments without heavy resource requirements.

Step-by-Step Authentication Flow of LDAP Proxy

Step 1: User Initiates Login

A user attempts to log in using an LDAP client (e.g., an application, VPN, or system connected to your LDAP). This action generates an LDAP bind request.

Step 2: Proxy Interception

The miniOrange LDAP Proxy intelligently intercepts this bind request. It acts as a secure intermediary, ensuring the request doesn't directly reach your LDAP server.

Step 3: Credential Verification

The proxy securely forwards the user's initial username and password (credentials) to your LDAP server for standard verification.

Step 4: MFA Challenge Triggered

If the credentials are verified successfully and Multi-Factor Authentication is enabled for the user, the LDAP Proxy triggers a secondary authentication prompt via the miniOrange services.

Step 5: User Responds to MFA

The user receives and responds to the MFA challenge. This will be a push notification on their mobile device, which you can allow or deny via email, SMS, or another configured MFA method.

Step 6: Access Decision Made

Based on the user's MFA response:

Successful MFA: If the MFA challenge is completed successfully, the miniOrange LDAP Proxy sends a successful bind response back to the LDAP client, granting the user access.

Failed MFA: If the MFA challenge fails (e.g., incorrect code, no response), the proxy denies access, effectively preventing unauthorized entry even if the initial LDAP credentials were correct.

Essential Elements of LDAP Authentication

Architecture of LDAP Proxy

Load Balancing for Optimized Performance

Distributes authentication requests across multiple LDAP servers, preventing overload and reducing latency. Ensures seamless access, minimized downtime, and improved efficiency.


Efficient TLS Offload Handling

Handles TLS termination separately to reduce server workload while maintaining encrypted authentication. Enhances security, prevents interception risks, and ensures compliance with encryption standards.


Google LDAP Integration for Cloud Compatibility

Seamlessly integrates with Google Secure LDAP, enabling secure authentication for cloud environments. Supports MFA and access controls across Google Workspace and third-party apps.


Auditing & Detailed Authentication Reports

Tracks authentication events with real-time audit logs for login attempts, MFA verifications, and failed access requests. Enables compliance, anomaly detection, and proactive security monitoring.

Security and Compliance Benefits

Fortified Against Unauthorized Access

Traditional LDAP's reliance solely on passwords leaves it vulnerable. miniOrange transforms this by adding layered authentication, effectively preventing breaches even if credentials are compromised, strengthening your security posture.

End-to-end Encrypted Communication

Beyond basic authentication, the proxy ensures all LDAP requests are fully encrypted via TLS. This eliminates the inherent risks of unsecured connections, safeguarding your sensitive data in transit.

Streamlined Compliance Adherence

The miniOrange LDAP Proxy is engineered to help your organization meet stringent security and data privacy regulations. It provides the controls necessary to comply with key standards.

Use Cases for miniOrange LDAP Proxy

Enterprises Using Legacy LDAP Authentication

Businesses that rely on LDAP but need modern security enhancements can integrate miniOrange’s MFA layer without modifying their core infrastructure.

Government and Defense Agencies

Critical national security systems require multi-layered authentication to safeguard sensitive intelligence and citizen data. We ensure only verified personnel gain access.

Financial and Healthcare Institutions

Banks, insurance providers, and healthcare organizations require strong authentication and compliance. We help meet HIPAA, PCI-DSS, and financial security standards.

Law Enforcement and Criminal Justice Systems

LDAP Proxy provides essential identity verification beyond passwords, ensuring authorized personnel access vital information like sensitive case files, criminal databases.

Cloud and IT Service Providers

Implementing MFA with the LDAP Proxy is crucial for secure remote access, protecting client data and internal systems from unauthorized entry.
