Re: [Mibble-users] Functionality of SNMPv3

[Birgit Arkesteijn]

Dear Bubul,

Try giving contextEngineID a (correct) value. Your original posting
mentions you keep it empty. 

You might also have to set contextName, like Per did in his example.
However, if contextEngineID is correct and contextName wrong, I do think 
you will receive a different error message.

Cheers, Birgit
