guacamole-user-sync

Synchronise a Guacamole PostgreSQL database with an LDAP server, such as Microsoft Active Directory

Running with Docker

You can run this Docker image as follows

console $ docker run -it \ -e LDAP_HOST=$(your LDAP server host) \ -e LDAP_GROUP_BASE_DN=$(your LDAP group DN) \ -e LDAP_GROUP_FILTER=$(your LDAP group filter) \ -e LDAP_USER_BASE_DN=$(your LDAP user DN) \ -e LDAP_USER_FILTER=$(your LDAP user filter) \ -e POSTGRESQL_HOST=$(your PostgreSQL server host) \ -e POSTGRESQL_PASSWORD=$(your PostgreSQL connection password) \ -e POSTGRESQL_USERNAME=$(your PostgreSQL connection username) \ ghcr.io/alan-turing-institute/guacamole-user-sync:$(version you want to use)

LDAP filter syntax is described here: https://ldap.com/ldap-filters/. If you want a simple filter for testing, try (objectClass=*) which will match any LDAP object.

Similarly, LDAP distinguished names (DNs) are described here: https://ldap.com/ldap-dns-and-rdns/. The user or group base DN will typically be the organisational unit (OU) that all objects of that type belong to. For example, a simple user base DN might look something like OU=users,DC=example,DC=com.
