Hi Lincoln,
I don't believe this is currently available out of the box. This might require a customer connector so the best option would be to open an "Idea" on CA Identity Manager community site for others to vote on it (requesting such a connector) and let our Product Management act on it.
In the mean time, you can review Connector Server SDK and ConnExpress documentation with respect to JNDI, JDBC, SCIM/WebService, OR Java Code based custom connector.
Thanks,
Hitesh
