## Presentation

LLNG can use GPG to authenticate users. It is not useful for day-to-day authentication but can be used for example if user has lost his password. The login form will ask user to sign a challenge and post result.

### Configuration of LemonLDAP::NG

In Manager, go in `General Parameters` > `Authentication modules` and choose GPG for authentication, users and/or password modules. Then you just have to set GPG database. For example `/usr/share/keyrings/debian-keyring.gpg`

You can then choose any other module for users and password.

Then, go in `GPG parameters`:

- Authentication level: authentication level for this module
- GPG database: database to store users GPG public key
