ok, this problem seems to be a valid candidate for bugzilla, 
and it should be easy to reproduce, I'd guess you Sumit 
might be interested.
How to - just have your sssd already configured to use an 
ldap backend for both password & users, have your (open)ldap 
run on non-conflicting ports and then try:
$ ipa-server-install -p ${myPass} -a ${myPass} --setup-dns 
--no-forwarders
process completes without errors but sssd fails and kerberos 
won't work. Suffices to disable ldap & sssd in 
authentication pipeline (prior to ipa installer run) and 
installer successfully sets up sssd and kerberos works.
That error:
Failed to read keytab [default]: Bad address
was saying a lot, that was default domain in sssd conf which 
was set up to ldap, and ipa installer was doing something 
with it.
I'm only puzzled nobody stumbled upon it earlier.
What do you think Sumit?
I'm going to dive deeper into ipa to see if it really is 
okey now.
