Authenticate users getting data from two different Data Sources

[Ja. C.A.]

Hi list

I 'd like to deploy FR to authenticate users, but I need FR to build the 
Authentication reply grabbing/merging info from two different data sources:

- user/password checking -> from LDAP server
- IP address assignment, DNS servers, etc -> from MySQL server

Once FR has info from these two data sources, it should send the Access 
Reply...

Is this config possible?

Thanks in advance,
M.
