<div>OS: CentoOS 7.1<br>

IPA: 4.1.0-18<br>

SSSD: 1.12.2-58<br>
<br>
</div>
With IPA any clients running CentOS7.1 authentication
for ssh and sudo takes more than 5 seconds _after_
putting in password. If ssh to the IPA server itself,
it authenticates instantly.<br>
<br>
</div>
Google did not provide much relevant information. Note
that this is not a slow ssh session to get to
authentication prompt, it always gets to the prompt
without delay.<br>
<br>
</div>
Also it is not related to NFS performance, it is equally
slow if I login to a NFS server (IPA client) locally or
login to a server (also a IPA client) that has autofs
home.<br>
<br>
</div>
<div>IPA server is a fresh installation with just a couple
of users. I had an installation previously that has more
than a thousand user accounts on CentOS 6. Users did not
have the slowness problem as with this new installation. <br>

Hope this list can provide some pointers.<br>

Thanks in advance.<br>

You might try changing /etc/nsswitch.conf and remove SSS from
suoders. I have been finding this slows down a lot of operations.
Not sure if it is the same as your problem, but it can't hurt to try
it.<br>
