RBMK

This is a rather simple Ruby LDAP server that proxies operations upstream but at the same time provides a facility to invoke your code at certain points in the operation runtime. This may help to accomodate for some clients that are not smart enough to implement the logic you need themselves. LDAP is very rigid and static in its nature and although OpenLDAP provides some very helpful overlays, it is far from enough. //: # (DESCRIPTION STOP)

Like its name suggests, rbmk is somewhat powerful, but is not very stable. Expect random meltdowns! Please, NEVER run it as superuser. LDAP gems that it uses are surprisingly feature-rich, but are not quite polished yet. This user does not have the time to rewrite them and does not consider it a huge problem. Remember, the best architecture is not the one that never fails, but is instead the one that can handle failures gracefully.

• This proxy is read-only, by design.
• This script does not detach from its terminal, again by design.
• Only simple binds, at least until I actually need SASL myself.
• No TLS for now, but maybe someday.
• Only tested with MRI 2.2, but will likely work with anything 1.9+.
• Well, maybe not anything, as it uses ruby-ldap (a C extension).

gem install rbmk, simple as that.

As this script is not a daemon, you have two easy options besides anything you may invent yourself:

• use any supervisor that are plenty nowadays: supervisord, bluepill etc.
• or just run it inside a tmux session and leave it there.

rbmk FILENAME, where FILENAME is a configuration file.

Upon its invocation rbmk evals its first argument and thus is configured by your Ruby code inside that file. Please refer to examples/rbmk.rb for an example configuration file.
