Can you tell us what version (package) of unixODBC you are running?
It's quite possible that the version that CentOS/RHEL ship with CentOS 7 is somewhat older than the version that has the vtable entry.
...in which case the centos build would fail.....as it would be built against such libraries with the same version includes etc ? - was this a self-built FreeRADIUS server or from RPM?
Fair enough. I'd also check that freetds is installed. The .so refers to that, so if it's not part of the SPEC file pre-requisites, then yes, freetds needs to be installed.
