# Introduction

For an overall understanding of the SAML authentication feature, read the [Overview](/sonarqube-server/2025.1/instance-administration/authentication/saml/overview.md) page.

To set up SAML with Microsoft Entra ID:

1. If you want to use [Overview of authentication and provisioning](/sonarqube-server/2025.1/instance-administration/authentication/overview.md#justintime-provisioning) with the group synchronization feature, verify the user groups in SonarQube Server so that the automatic group synchronization can take place properly.
2. Register SonarQube server in Entra ID. See the [Setup in Microsoft Entra ID](/sonarqube-server/2025.1/instance-administration/authentication/saml/ms-entra-id/setup-in-entra-id.md) page to get started.
3. Configure SAML in SonarQube Server; instructions are on the[Setup in SonarQube Server](/sonarqube-server/2025.1/instance-administration/authentication/saml/ms-entra-id/setup-in-sq.md) page.
4. If you want to use SCIM provisioning, follow the instructions on the [With Microsoft Entra ID](/sonarqube-server/2025.1/instance-administration/authentication/saml/scim/scim-provisioning-with-azure-ad.md) page.
5. Optionally, set up security features; see the [Setup of security features](/sonarqube-server/2025.1/instance-administration/authentication/saml/ms-entra-id/optional-security-features.md) page.

{% hint style="warning" %}

* Group synchronization doesn’t work with Microsoft Entra ID’s nested groups.
* Microsoft Entra ID SAML tokens have a limit regarding the number of groups a user can belong to (see the description of groups in the [Claims in SAML Token](https://learn.microsoft.com/en-us/entra/identity-platform/reference-saml-tokens#claims-in-saml-tokens) table). In such cases, you might need to reduce the number of groups the user is in.
