A fake LDAP server for use in testing

Ldumbd is a simple, self-contained read-only LDAP server that uses PostgreSQL, MySQL/MariaDB or SQLite as a back end.

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.
