In general, MySQL 5.xxx is supported by Telerik OpenAccess ORM. The limitations of the free edition are regarding the version of the database - you should be able to use any free edition of MySQL, but not commercial editions.
However, since our connectivity with MySQL is not tested on a FreeBSD server, we cannot currently guarantee that the version number returned by such an installation would fit our parsing algorithms. If the format is changed due to the different operating system, there is a possibility for OpenAccess ORM to reject the connection.
The expected version format is N.N.N where the first position is for the major version, the second for the minor and the third for the build number / patch number. For example - 5.5.12 will be recognized.
Unfortunately, there is no easier way of determining if your particular installation on FreeBSD would be accepted by OpenAccess ORM other then creating a sample project and testing it locally. Please accept our apologies for the inconvenience caused. We will discuss providing an easier way of testing a database for compatibility in one of the future releases.
