Can you confirm this issue: SNMP v3 works only with some passwords and users?!

Ex: user: v3user

1.
MT: authentication-password=1234 encryption-password=4321
Dude: authentication-password=1234 encryption-password=4321 - Works fine
Windows client works too.

2.
MT: authentication-password=123456 encryption-password=654321
Dude: authentication-password=123456 encryption-password=654321 - Doesn't work !!!!
Windows client works with new passwords !!

3.
MT: authentication-password=12345678 encryption-password=87654321 Again both Dude and windows client works fine.

Passwords tripple checked, I'm sure.

Moreover: authentication-password=12345678 encryption-password=87654321 both Dude and windows client works fine with "v3user". When i change it to "v3admin" Windows OK, Dude fails also tripple checked.

Can anyone donfirm?

I tried but here it doesn't work. Are you sure? I have the same problem - Windows Server and Dude can't talk each other.
