Murmur LDAP authentication

This project provides an LDAP-backed server authenticator for Murmur, the standard Mumble server.

It supports delegating authentication based on usernames and passwords to any LDAP directory, as well as returning user groups to Murmur.

This makes it possible to, for example, control Murmur's default 'admin' group through LDAP.

Building

The project uses ICE to communicate with Murmur based on code generated at build time.

ICE needs to be installed before you can build this project.

To generate the necessary classes, compile the project and create an uberJAR simply run gradle shadowJar.

Configuring

A configuration file in Java properties format is expected by the app. The file should take the following format:

# LDAP configuration
ldapHost=127.0.0.1
ldapPort=389
userFilter=(objectClass=*)
usernameAttribute=cn
userBase=ou=users,dc=tendollarbond,dc=com
groupBase=ou=groups,dc=tendollarbond,dc=com
groupMemberAttribute=member

# Murmur / slice configuration
murmurHost=127.0.0.1
murmurPort=6502
murmurSecret=TrumpForPresident2016

The keys ldapHost, ldapPort, usernameAttribute, groupMemberAttribute, murmurHost and murmurPort are optional and default to the values in the example above.

Running

Start the service with java -jar murmur_ldap_auth.jar [config-location]. If no configuration file is specified it is expected in the file murmur-auth.conf in the current working directory.
