this didn't work anymore in the 2.4 client. Easy work-around, use the FQDN instead.
In 2.4, the id_dsa did not work. And explicitly specifying it via IdentityFile in

r20866 fixes the issue where it would only try the first key it finds, this will be included in 2.4.1 - thanks for reporting that
In the meantime, you can also switch back to the old openssh backend with
