SNMP error - An empty authproto specified

Hi Team,

I am using OCS NG Server 2.2 on Centos and Ocs Client 2.1 also configured on CentOs.

When we are trying to fetch Server which has configured SNMP V3 I got a error message in ocsagent log file is

"An empty authproto has specified: can not communicate SNMP"

Pls help to resolve this..
