vaultwarden_ldap

An LDAP connector for vaultwarden

After configuring, run vaultwarden_ldap and it will invite any users it finds in LDAP to your vaultwarden instance.

Deploying

This is easiest done using Docker. See the docker-compose.yml file in this repo for an example. If you would like to use Docker Hub rather than building, change build: . to image: vividboarder/vaultwarden_ldap.

Make sure to populate and mount your config.toml!

Development

This repo has a predefined set of pre-commit rules. You can install pre-commit via any means you'd like. Once your system has pre-commit installed, you can run make install-hooks to ensure the hooks will run with every commit. You can also force running all hooks with make check.

For those less familiar with cargo, you can use the make targets that have been included for common tasks like running a debug version. make run-debug or building a release version make release.

Testing

All testing is manual right now. First step is to set up Bitwarden and the LDAP server.

docker-compose up -d vaultwarden ldap ldap_admin

1. After that, open the admin portal on http://localhost:8001 and log in using the default account info:

   Username: cn=admin,dc=example,dc=org Password: admin

From there you can set up your test group and users.

2. Expand the dc=example,dc=org nav tree and select "Create new entry here"

3. Select "Generic: Posix Group"

4. Give it a name, eg. "Users" and then save and commit

5. Select "Create child object"

6. Select "Generic: User Account"

7. Give the user a name and select a group ID number and save and commit

8. Select "Add new attribute" and select "Email" and then add a test email address

9. Run the ldap sync

docker-compose up ldap_sync

Alternately, you can bootstrap some of this by running:

docker-compose -f docker-compose.yml -f itest/docker-compose.itest.yml up --build

Future

• Any kind of proper logging
• Tests
