| Subject: | password autentication broken connecting to suse servers |
The recent flag to prefer authentications breaks password authentication to SuSE. The reason
for this is that 'password' is not an authentication method in their list. The attached patch
fixes this by also trying keyboard-interactive after password. All of my SuSE environments
are straight out of the box installs without modification.
