 Issue description   

While configuring the Entra ID (formerly Azure AD) tenant in ManageEngine ADAudit Plus, you may encounter the following error message:

Invalid_Client

This error prevents successful integration of Entra ID with ADAudit Plus and typically relates to incorrect credentials provided during configuration.

 Prerequisites   

Before beginning troubleshooting, ensure:

• You have administrative access to both ADAudit Plus and the Entra ID  portal.

• You have access to the Entra ID  App Registration used for ADAudit Plus integration.

• You have permissions to generate and view Client ID and Client Secret in Entra ID.

 Possible causes   

• The Client ID entered in ADAudit Plus does not match the registered the Entra ID application.

• The Client Secret provided is incorrect or expired.

• The wrong value (e.g., “Secret ID” instead of “Value”) was copied during secret generation.

• The Client Secret was generated earlier and not copied immediately, making it inaccessible.

 Resolution   

 Step 1: Verify the Client ID   

1. Go to the Entra ID portal.

2. Navigate to: Entra ID > App registrations > [Your App]

3. Copy the Application (client) ID from the Overview section.

4. Ensure this ID is the same one entered in ADAudit Plus > Cloud Directory > Configuration > Cloud Directory.

 Step 2: Verify the Client Secret   

1. In the same Entra App Registration, go to:
   Certificates & Secrets > Client Secrets

2. If no active secret exists, click + New client secret.

3. After creating the secret:

• Copy the Value, not the Secret ID.

• Paste the value immediately into ADAudit Plus, as you will not be able to retrieve it later.

Note: If the Value was not copied earlier, generate a new client secret.

 Step 3: Reconfigure the Entra ID  Tenant in ADAudit Plus   

1. Go to ADAudit Plus > Cloud Directory > Configuration > Cloud Directory.

2. Enter the correct Client ID and newly generated Client Secret Value.

3. Save and test the connection.

If entered correctly, the integration should complete without the Invalid_Client error.
