For those still interested on this topic, there will soon be a new version comming.
ldap implementation for the overleaf community edition overleaf
Work by kemnitzs and worksasintended.
This solution uses ldapjs.
Edit docker-compose.yml to fit your local setup.
ADMIN_MAIL: login for local admin user which gets checked before the ldap routine during login. This is the only user that can login if ldap is down and does not need to exist in ldap. You need to create the same user in overleaf, for example using the launchpad. The admin user does not have to be in the same domain as other users. DOMAIN: At the current state, only users of a single domain are allowed (though easy to change). For a given user user123@domain123.com trying to login, domain123.com is compared with DOMAIN. For the ldap authentification only the username user123 is used. LDAP_SERVER: address of the ldap serverLDAP_BIND_DN: bind dn which allows to search users inside ldapLDAP_BIND_PW: secret corresponding to LDAP_BIND_DNFor persistent storage use volumes. For secure connections either use nginx-proxy or add the certificate to nginx inside the worksasintended/overleaf-ldap container and adjust nginx settings accordingly.
docker-compose up -d
The image worksasintended/overleaf_ldap is available at dockerhub
You can also build it yourself simply using the docker build command or the build script.
