Unable to connect to data source

["johnson elangbam" <elangbamjohnson@gmail.com>]

hi,
    I am trying to connect Ms SQL with free radius, I've configure all the related packages like freeTDS and unixodbc , and both of the package work well when I test using "tsql" and "isql". But when I try to link with free radius, the following errors shows.Please tell what might be the proble for the following errors.

rlm_sql (sql): Driver rlm_sql_unixodbc (module rlm_sql_unixodbc) loaded and linked
rlm_sql (sql): Attempting to connect to adore@MSSQL:/radius
