SNMP error

[Amr el-Saeed]

Dear All,

I have freeradius-1.1.7-1.
it was installed on RHEL 3
SNMP  net-snmp-5.0.9-2.30E.22

every thing was going OK

i just installed RHEL 5    64-bit
recompiled the freeradius on the new OS and reinstall
the radius is working Ok
i have SNMP version     net-snmp-5.3.1-19.el5

but every time i wanted to snmpwalk from the radius i got that error "  
RADIUS-AUTH-SERVER-MIB::radiusMIB = No Such Object available on this 
agent at this OID  "

the command i execute is " snmpwalk -v2c -c testsnmp -m 
/etc/raddb/RADIUS-AUTH-SERVER-MIB.txt  localhost radius "
 same command is working fine on the old machine.

i searched  for that on google but found nothing .

any one can help ??

thanks
Amr
