Scripts executing in acct_users file

[Eugen Vakulenko]

Hi all!

I've just upgraded from 1.1.6 to 2.1.9. On the old server I'm used 
Start/Stop and Interim-Update in acct_users file to execute some script 
in this way:

DEFAULT Acct-Status-Type == Start
         Exec-Program = "/usr/local/etc/raddb/aaa_pdsn.sh"
DEFAULT Acct-Status-Type == Interim-Update
         Exec-Program = "/usr/local/etc/raddb/aaa_pdsn.sh"
DEFAULT Acct-Status-Type == Stop
         Exec-Program = "/usr/local/etc/raddb/aaa_pdsn.sh"

But when I try it on the new server it seems it doesnt work.
exec is enabled:

Optimus# less /usr/local/etc/raddb/sites-enabled/default
...
post-auth {

#       main_pool
#       reply_log
#       sql
#       sql_log
#       ldap
         exec
#       wimax
         Post-Auth-Type REJECT {
                 attr_filter.access_reject
         }
}

What is the best way to make it work?
