When opening an autoinst.xml with an <auth-client /> section, there is this
error,

/usr/share/YaST2/clients/auth-client_auto.rb failed with 'undefined method
`has_key?' for "yes":String' (NoMethodError).

Also, "LDAP and Kerberos Client" in "Autoinstallation Configuration" does not
show anything at all.

And Cloning a system also doesn't output any <auth-client /> configuration in
autoinst.xml.
