Microsoft Entra ID and M365 SharePoint - Oleria Identity Security

Oleria provides identity security and access management teams with visibility and intelligence into who has access to what, where they got that access, how they use it, and if they should even have it. As part of that promise, we integrate applications such as Microsoft Entra ID and M365 SharePoint into the Oleria platform. We provide multiple options for each integration and this document provides step-by-step guidance for integrating Entra ID and M365 SharePoint with your Oleria workspace.

Prerequisites

The user granting these permissions must have Global Admin privileges.

Standard integrations are configured with read-only permissions. If you would like to take advantage of Oleria’s access remediation capabilities, which are completely optional, you need to configure additional privileges required for write access.Use a service account (and not an employee account) with the suggested privileges for the integration to ensure continuity.

Integration Approaches

Oleria currently supports three approaches. Follow the one that is most appropriate for your organization.

Authenticate via Microsoft (automated configuration via OAuth)
Client Secret Authentication (manual configuration)
Client Certificate Authentication (manual configuration)

Authenticate via Microsoft (OAuth)

Open the integration

Select Microsoft Entra ID to integrate Entra ID, or
Select Microsoft SharePoint and OneDrive to integrate Entra ID, SharePoint, and OneDrive.

A side panel opens.

Choose permission scope

The screen shows an option to enable write permissions to allow Oleria to perform select remediations. The Oleria remediation feature is optional.To enable remediations, select the checkbox. Otherwise, select Authenticate to proceed with the standard read-only permissions scope.

Client Certificate Authentication

Client certificate authentication uses a certificate uploaded to your Oleria app registration in Entra ID and a base64-encoded private key stored by Oleria. Use this method when your security policy requires certificate-based service principal authentication instead of a client secret.

This flow reuses the Oleria app registration and API permissions you create in the Client Secret Authentication section. Complete the steps from Create an app registration in Entra ID through Confirm admin consent, then return here. Skip the Create a client secret step.

Prepare your certificate files

Place the following files in a single working directory:

certificate.pem - the public certificate in PEM format
private_key.txt - the matching unencrypted private key in PEM format
certificate_chain.txt - the intermediate certificate chain in PEM format

If your organization does not issue these files through an internal PKI, generate a self-signed certificate using the tooling of your choice (for example, AWS Certificate Manager Private CA or New-SelfSignedCertificate on Windows) and export it in the formats above.

The private key must be unencrypted. If private_key.txt is passphrase-protected, decrypt it first with openssl rsa -in private_key.txt -out private_key.txt (or the equivalent for your key type) before continuing.

Generate the base64-encoded private key

Oleria expects a single base64 string that decodes to the certificate, chain, and unencrypted private key concatenated as PEM blocks. Run the commands for your operating system from the directory that holds the files prepared in the previous step.

macOS or Linux
Windows (PowerShell)

cat certificate.pem certificate_chain.txt private_key.txt > generated_cert.pem
base64 < generated_cert.pem | tr -d '\n' > base64_generate_cert.pem

Get-Content certificate.pem, certificate_chain.txt, private_key.txt |
    Set-Content generated_cert.pem
[Convert]::ToBase64String([IO.File]::ReadAllBytes("generated_cert.pem")) |
    Set-Content base64_generate_cert.pem -NoNewline

The contents of base64_generate_cert.pem is the value you will paste into Oleria in the final step.

Upload the certificate to Entra ID

Sign in to your Entra ID tenant and navigate to Microsoft Entra ID -> Manage -> App registrations. Open your Oleria app registration.

If the app is not visible under Owned applications, switch to All applications and search for it by name.

Select Manage -> Certificates & secrets -> Certificates and upload certificate.pem.

Open the integration in Oleria

For a new integration, select Microsoft Entra ID or Microsoft SharePoint and OneDrive to open the side panel.
To migrate an existing integration from client secret to client certificate, select Connected, then select the edit icon on your Entra ID integration to open the side panel.

Authenticate with the client certificate

From the Authentication Method dropdown, select Client Certificate Authentication.Provide the following:

Field	Notes
Tenant ID	Your Directory (tenant) ID from the app registration overview.
Client ID	Your Application (client) ID from the app registration overview.
Private Key	The contents of `base64_generate_cert.pem` from the previous step.

Select Update to save the integration.

Clean up generated files

generated_cert.pem and base64_generate_cert.pem both contain the unencrypted private key inline. Delete them from the working directory now that the integration is connected. Your original certificate.pem, certificate_chain.txt, and private_key.txt files are unchanged and can stay in your existing key store.

macOS or Linux
Windows (PowerShell)

shred -u generated_cert.pem base64_generate_cert.pem 2>/dev/null || \
  rm -P generated_cert.pem base64_generate_cert.pem

Remove-Item generated_cert.pem, base64_generate_cert.pem -Force

For a stronger overwrite guarantee on a spinning disk, run cipher /w:<directory> against the working directory from an elevated command prompt. On an SSD this is a no-op due to wear leveling.

If your shell records command history, clear it to remove references to the key file paths: history -c on Bash or Zsh, Clear-History on PowerShell.

How Oleria handles the private key

The Private Key field in the integration form is masked to prevent shoulder-surfing during entry. The value is transmitted to Oleria over TLS and persisted in AWS Secrets Manager, which provides encryption at rest with KMS-managed keys and audit logging on every access. Access to the secret is scoped to the Oleria service that authenticates to Entra ID; no human operator and no other Oleria service can read it. Oleria does not write the private key to application logs, databases, or temporary files. It is read from AWS Secrets Manager into process memory only when authenticating to Entra ID, and is held in memory only for the duration of that authentication.
