Hi,

For begin I read the manual, FAQ and some resourses founded in web, but I can't find any complete guide, how install and configure freeradius with module rlm_sql_firebird on ubuntu server, and how I can get this module or compile it, desirable of standard package system of Ubuntu.

you will need to compile from source as per guides - whether you follow the 'make your own DEB' gudie or just install from source is up to you. you will need to have the relevant firebird development files/headers around for the server to build with firebird support. you then configure the relevant raddb config files to use that module and configure the firebird module as required. alan
