Hello, rlm_sql_firebird module in freeradius 1.1.4 should not be used because of some serious bugs. I posted fixes on http://bugs.freeradius.org/show_bug.cgi?id=378, but they were did not issued. So if someone brave enough to take a risk of using or testing this module, he should download last source code files from this attachment http://bugs.freeradius.org/showattachment.cgi?attach_id=186. For a future, if this module will be continued in the freeradius project, how I can post changes or fixes for it?
