How to do it?

[ELOM ETSE]

Thank you for your contribution. 
I have now another problem.
When i boot with the command radiusd -X, i have this result:
radiusd: #### Instantiating modules ####
 instantiate {
/usr/local/etc/raddb/modules/exec[24]: Failed to link to module 'rlm_exec': rlm_exec.a: cannot open shared object file: No such file or directory 
Errors initializing modules

Please what must i do to resolve this problem?
Thanks
