dBUB is permissions bridging plugin that was designed to bridge permissions between an online database, and permissions on your minecraft server!

What is it?
The Database User Bridge, dubbed dBUB, is permissions bridging plugin that was designed to bridge permissions between an online database, and permissions on your minecraft server! Currently, it may only work with group manager, the in future releases will work with other popular permissions systems such as PermissionsEx, bPermissions, and permissionsBukkit.

What exactly does it do?
Based on your configuration settings, dBUB will try to synchronize user's groups from your database with your permissions system based on their group ID in the database (which you can map to any group you'd like in dBUB's configuration file!) when they log into your server!

Features:

Support for (almost) any database user setup!
Support for using different tables!
Supports Database -> Server Synchronization!
Supports Server -> Database Synchronization!

Future Features:

Vault support (Permissions 3, bPermissions, PEX, GroupManager, PermissionsBukkit, zPermission)
