[SNMP4J] null in authPassPhrase..even though initialized user to "authUser"

[Rajesh Reddy]

Hi,
Agent simulator is configured with authUser with the authentication password
of authUser.
when i am sending request to that simulator in other machine ...it is
returning usmuser unknown.
Then i varified the usm user name it is sending, user name is Correct ,but
the authpassphrase is null.
If i send the same request with noauth protocol then it is working fine (as
for noauth passphrase is null).
but with authentication protocol and private protocol it is returning
unknown User as it is sending null in both the passphrases.

is there any other way to set passphrase? (other than initializing through
constructor) or how can i get the response from the agent by using
authentication through snmp4j.

Regards,
Rajesh.

Hi Rajesh,

The behavior is intended. The returned UsmUserEntry
represents a localized user. Therefore the contained
UsmUser class does not contain any passphrases.

Why do you think that you need any help here?
In other words, what are you trying to accomplish?

Best regards,
Frank
