returned value differ : from shell or from snmpd

Hello,

snmpd works on a Debian GNU/Linux machine. I have installed shell scripts. I want to be able to monitor the
RAID status of an hardware RAID (LSI) with SNMP.

here is the line I have in snmpd.conf :

############################## CUT
exec .1.3.6.1.4.1.2021.8.5.101.1 check_raid /bin/bash /usr/local/bin/check_raid.sh
############################## CUT

In a root shell, I have this output :
############################## CUT
# /usr/local/bin/check_raid.sh
OK: LSI Megaraid 1030 Volume State Optimal
############################## CUT

In an snmp user's shell, I have this output : (works with sudo)
############################## CUT
$ /usr/local/bin/check_raid.sh
OK: LSI Megaraid 1030 Volume State Optimal
############################## CUT

But now with SNMP, in a root shell, I have this :
############################## CUT
# snmpwalk -v 2c -On -c public 127.0.0.1 .1.3.6.1.4.1.2021.8.5
.1.3.6.1.4.1.2021.8.5.101.1.1.1 = INTEGER: 1
.1.3.6.1.4.1.2021.8.5.101.1.2.1 = STRING: "check_raid"
.1.3.6.1.4.1.2021.8.5.101.1.3.1 = STRING: "/bin/bash /usr/local/bin/check_raid.sh"
.1.3.6.1.4.1.2021.8.5.101.1.100.1 = INTEGER: 0
.1.3.6.1.4.1.2021.8.5.101.1.101.1 = STRING: "CRITICAL: NO RAID FOUND"
.1.3.6.1.4.1.2021.8.5.101.1.102.1 = INTEGER: 0
.1.3.6.1.4.1.2021.8.5.101.1.103.1 = ""
############################## CUT

Where does this difference come from?

Here is an extract of the python script :
############################## CUT
if is_3ware():
        print check_3ware()
    elif is_linuxraid():
        print check_linuxraid()
    elif is_lsi1030():
        print check_lsi1030()
    elif is_i2o():
        print check_i2o()
    else:
        print "CRITICAL: NO RAID FOUND"
############################## CUT

Note : I thougt the problem came from the PATH. So I wrote the following script. Here is the full content of
/usr/local/bin/check_raid.sh :
############################## CUT
#!/bin/bash

export PATH=/usr/local/bin:/usr/bin:/bin
/usr/local/bin/check_raid
############################## CUT

So, why the returned value differ ?
* With the script directly from a shell : returned value = OK: LSI Megaraid 1030 Volume State Optimal
* With SNMP : returned value = CRITICAL: NO RAID FOUND

Thank you for your help.
