Error. Cannot install public key for specified user

Question

I'm getting "Error. Cannot install public key for specified user" when trying to add a public ssh key for a service processor user on a V20z. I've tried it for different users and still get the error. The same operation works fine on a V40z. Any help would be appreciated.

Answer 1

That would be great if the resolution was that simple.  I am using a public key I generated using the putty key generator.  Below is the key I would use if I got that far.  However I get an error on the "ssh authentication publickey" attribute so I never get the chance to enter a public key.  What code version and hardware version are you running that this worked on?
