Hello,

I just did a 'yum update' from CentOS 6.5 -> 6.6 on my freeipa system
(master and 2 replicas) and I seen to have run into the following bug,

https://bugzilla.redhat.com/show_bug.cgi?id=953653

On Master:

In the ticket, Scott Poore says he increased the
nsslapd-sasl-max-buffer-size to work around the problem.  Is this the
correct course of action, or should I be trying something else?

Thanks,
Mike
