# Introduction

With the GitLab authentication and provisioning, you can use Just-in-Time (JIT) provisioning. With this mode, user accounts are created in SonarQube Community Build when GitLab users log in for the first time. You can use group synchronization and user access restriction features.

{% hint style="info" %}
When authentication is delegated to GitLab in SonarQube Community Build, the user’s email address is synchronized with GitLab at each login to SonarQube Community Build.
{% endhint %}

{% hint style="info" %}
SonarQube Community Build doesn’t support the automatic provisioning mode. See [Feature comparison table](/sonarqube-community-build/feature-comparison-table.md) to find out which SonarQube deployments support this feature.
{% endhint %}
