OK - so either the agent doesn't support these objects,
or the access control settings are blocking access to them.
What access control do you have in the snmpd.conf file.

Yes - but think about what is implied by "multiple" here.
snmpwalk will sent GetNext requests until it decides to stop.
It decides to stop when it receives a response that falls
outside the desired range.
So in this case,
snmpwalk sends a GetNext request for snmpEngine (1.3.6.1.6.3.10.2.1)
It receives a response containing vacmGroupName.1."public"
(1.3.6.1.6.3.16.1.2.1.3....)
This lies outside the snmpEngine subtree (1.3.6.1.6.3.16 vs 1.3.6.1.6.3.10)
so it discards the response, and stops.
