This turned out to be a setting in /etc/ssh/sshd_config which gets overridden 
by ipa-client-install. Needed to un-comment

PasswordAuthentication yes

Subject: [Freeipa-users] 14: No supported authentication methods available

I have an AWS instance running Centos 6.7 correctly configured for freeipa but 
I needed to make a backup machine which would remain live.

I created a clone of the machine and changed the host name and the settings in 
/etc/hosts. When I tried to run ipa-client-install it told me to run the 
uninstall which I did. This had the worrying effect of not being able to log 
into my original live server but thankfully after a while it came good. I don't 
know why.

Back on the new server I ran 'ipa-client-install --enable-dns-updates 
-mkhomedir' and it seemed to run ok. The host was created on the freeipa GUI 
and I added it to the same host group as the original server. But when I try to 
log in via SSH I get the error 'No supported authentication methods available'. 
I do have root access via the AWS Key file.

As far as I can tell all the relevant settings seem the same between the two 
servers but one works and the other doesn't. I can kinit and klist using my 
freeipa account. 'getent netgroup my-servergroup' works fine.

I can't seem to find anything relevant in the sssd logs and /var/log/secure 
just give me the same error of no supported authentication methods available

I have noticed in /var/log/messages when I restart sssd and error which may be 
relevant but can't find anything useful so far

sssd[be[]]: dereference processing failed : Input/output error
