Configuration

This file describe the configuration, it is recommended to edit the relevant *.secret.exs file instead of the others founds in the config directory. If you run Pleroma with MIX_ENV=prod the file is prod.secret.exs, otherwise it is dev.secret.exs.

Pleroma.Upload

• uploader: Select which Pleroma.Uploaders to use
• filters: List of Pleroma.Upload.Filter to use.
• link_name: When enabled Pleroma will add a name parameter to the url of the upload, for example https://instance.tld/media/corndog.png?name=corndog.png. This is needed to provide the correct filename in Content-Disposition headers when using filters like Pleroma.Upload.Filter.Dedupe
• base_url: The base URL to access a user-uploaded file. Useful when you want to proxy the media files via another host.
• proxy_remote: If you're using a remote uploader, Pleroma will proxy media requests instead of redirecting to it.

Note: strip_exif has been replaced by Pleroma.Upload.Filter.Mogrify.

:ldap

Use LDAP for user authentication. When a user logs in to the Pleroma instance, the name and password will be verified by trying to authenticate (bind) to an LDAP server. If a user exists in the LDAP directory but there is no account with the same name yet on the Pleroma instance then a new Pleroma account will be created with the same name as the LDAP user name.

• enabled: enables LDAP authentication

• tls: true to start TLS, usually implies the port 389
• tlsopts: additional TLS options
• base: LDAP base, e.g. "dc=example,dc=com"

Pleroma.Web.Auth.Authenticator

• Pleroma.Web.Auth.PleromaAuthenticator: default database authenticator
• Pleroma.Web.Auth.LDAPAuthenticator: LDAP authentication

BBS / SSH access

To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:

app_dir = File.cwd!
priv_dir = Path.join([app_dir, "priv/ssh_keys"])

config :esshd,
  enabled: true,
  priv_dir: priv_dir,
  handler: "Pleroma.BBS.Handler",
  port: 10_022,
  password_authenticator: "Pleroma.BBS.Authenticator"

Feel free to adjust the priv_dir and port number. Then you will have to create the key for the keys (in the example priv/ssh_keys) and create the host keys with ssh-keygen -N "" -b 2048 -t rsa -f ssh_host_rsa_key. After restarting, you should be able to connect to your Pleroma instance with ssh username@server -p $PORT
