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!

Configuration

Configuration is read from a TOML file. The default location is config.toml, but this can be configured by setting the CONFIG_PATH env variable to whatever path you would like.

Configuration values are as follows:

Name	Type	Optional	Description
vaultwarden_url	String		The root URL for accessing vaultwarden. Eg: https://vw.example.com
vaultwarden_admin_token	String		The value passed as ADMIN_TOKEN to vaultwarden
vaultwarden_root_cert_file	String	Optional	Path to an additional der-encoded root certificate to trust. Eg. root.cert. If using Docker see docker-compose.yml for how to expose it. Defaults to empty
ldap_host	String		The hostname or IP address for your ldap server
ldap_scheme	String	Optional	The that should be used to connect. ldap or ldaps. This is set by default based on SSL settings
ldap_ssl	Boolean	Optional	Indicates if SSL should be used and if we should connect with ldaps. Defaults to false
ldap_starttls	Boolean	Optional	Indicates if the connection should be done using StartTLS
ldap_no_tls_verify	Boolean	Optional	Indicates if certificate should be verified when using SSL. Defaults to true
ldap_port	Integer	Optional	Port used to connect to the LDAP server. This will default to 389 or 636, depending on your SSL settings
ldap_bind_dn	String		The dn for the bind user that will connect to LDAP. Eg. cn=admin,dc=example,dc=org
ldap_bind_password	String		The password for the provided bind user.
ldap_search_base_dn	String		Base dn that will be used when searching LDAP for users. Eg. dc=example,dc=org
ldap_search_filter	String		Filter used when searching LDAP for users. Eg. (&(objectClass=*)(uid=*))
ldap_mail_field	String	Optional	Field for each user record that contains the email address to use. Defaults to mail
ldap_sync_interval_seconds	Integer	Optional	Number of seconds to wait between each LDAP request. Defaults to 60
ldap_sync_loop	Boolean	Optional	Indicates whether or not syncing should be polled in a loop or done once. Defaults to true

Alternatively, instead of using config.toml, all values can be provided using enviroment variables prefixed with APP_. For example: APP_VAULTWARDEN_URL=https://vault.example.com

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

There are no unit tests, but there are integration tests that require manual verification.

Integration tests

Running make itest will spin up an ldap server with a test user, a Vaultwarden server, and then run the sync. If successful the log should show an invitation sent to the test user. If you run make itest again, it should show no invites sent because the user already has been invited. If you'd like to reset the testing, make clean-itest will clear out the Vaultwarden database and start fresh.

It's also possible to test passing configs via enviornment variables by running make itest-env. The validation steps are the same.

Steps for manual testing

The 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
