This might not be possible, but I am trying to connect a database on MS Access that is linked to an Oracle database, I want to know if there's possible way to connect those to FIM. The main attribute will be the User's ID, and couple other key attributes.

Out of the box, MS Access is not supported.  You can always create an extensible MA, Custom.

Here are the supported MAs.

Hello,

with the Generic SQL Connector you should be able to connect to any database you have an ODBC Driver for.

So in this Case it maybe is possible to connect to Access, since there is a ODBC Driver.

I do have the Access database on an ODBC driver.

Then I would give the generic SQL connector a try, it is currently still in preview since Nov'14 but there is a TAP program if you want to use that in production.

Check the connect site, and register free on it if you need to.
