Gitea Advanced LDAP User/Group Sync

This application is designed to sync LDAP users, groups (orgs and teams) and user membership to Gitea.

It can do the following:

• Create (and optionally delete) Gitea Users based on LDAP users.
• Create (and optionally delete) Gitea Organizations based on LDAP groups.
• Create (and optionally delete) Gitea Teams inside Organizations based on LDAP subgroups.
• Attach existing Gitea Users to appropriate Gitea Teams based on group membership information in LDAP.

The application is not going to sync users from LDAP to Gitea as Gitea provides a solution for that.

This application syncs users as well. We suggest to disable Gitea LDAP user sync (but you can still use Gitea's LDAP Provider).

Docker image available at ghcr.io/janosmiko/gitea-ldap-sync.

Usage

Docker Compose

Configure your settings in docker-compose.yml or copy config.yaml.sample as config.yaml and fill the settings (and uncomment the volume mount in docker-compose.yml`.

Modify the values in deploy/secret.yaml and deploy/job.yaml and apply them to Kubernetes.

kubectl apply -f deploy/secret.yaml
kubectl apply -f deploy/deployment.yaml
