Re: auth_pubkry callback is only getting called with signature_state == SSH_PUBLICKEY_STATE_NONE

I changed the return to SSH_AUTH_SUCCESS and am now I get the second authentication attempt and can authenticate.  So is the documentation wrong or am doing the wrong (but working) thing?

    I’ve tried calling my ssh server with the linux ssh app and also an libssh app using ssh_userauth_publickey_auto() and I get multiple calls to my auth_publickey() function but signature_state is always SSH_PUBLICKEY_STATE_NONE.  I’ve read that SSH_AUTH_PARTIAL is the appropriate response but I never get a call with another state.  Any hints at what I may be doing wrong?
