Role Base Access Control Provisioning Connector
The existing LDAP Provisioning Connector has LDAP knowledge built in at almost every level.

KU's Relational Database Provisioning Connector is better, but has too much knowledge built in at a low level in the synchronization code about what relational databases might look like.
