Description of problem:

When I add to /etc/ssh/sshd_config the line

HostbasedAuthentication yes

and when wie add to /etc/ssh/ssh_config the lines

HostbasedAuthentication yes
EnableSSHKeysign yes

then we get the following error messages when calling "ssh myhost" where "myhost" is listed in /etc/ssh/ssh_known_hosts and in /etc/ssh/shosts.equiv:

could not open any host key
ssh_keysign: no reply
key_sign failed

I called ssh with debug options "-vvv" - here are the important part for the message above:

debug3: authmethod_lookup hostbased
debug3: remaining preferred: publickey,keyboard-interactive,password
debug3: authmethod_is_enabled hostbased
debug1: Next authentication method: hostbased
debug2: userauth_hostbased: chost myhost.
debug2: ssh_keysign called
debug3: ssh_msg_send: type 2
debug3: ssh_msg_recv entering
debug1: permanently_drop_suid: 1292
could not open any host key
ssh_keysign: no reply
key_sign failed
debug2: we did not send a packet, disable method


I also set
setsebool allow_ssh_keysign on

but this doesn't change the error messages.
