I'd start by figuring out how exactly "Access Control" is configured in
your snmpd.conf file. Find out what security names you have configured,
what access those security names have and if you are using snmpwalk -v
2c -c "public" to walk the tree what does "public" community maps into.

Sample from our configuration we are using here (taken from snmpd.conf)
com2sec readonly default our_community
group MyROGroup v1 readonly
group MyROGroup v2c readonly
group MyROGroup usm readonly
view all included .1 80
access MyROGroup "" any noauth exact all none none

this will map community "our_community" (to get rid of default
"public") to security name "readonly", then map that security name into
group "MyROGroup", define view called "all" which includes full SNMP
tree and then give read-only access to group MyROGroup to view "all".

You haven't specified what exactly you are snmpwalk-ing remotely. The
OMSA branch or full system? 

Hope this is helpful

Misha.
