are there any IPV6 ipadresses in /etc/hosts   ( if so remove them and try again ) 

Or  you try to remove and/or disable IPV6 totaly. 
If ldapsearch uses IPv6, then things don't work 

This is known bug.

>1) Is it necessary to join the domain for SSSD to authenticate?
>2) Is there a need to have a computer record in Samba for the computer 
>with SSSD?
>3) Aside from joining the domain, is there anything else that has to 
>happen to allow the host to access the AD? I used:
>     net ads join -UAdministrator
>and got a success message.
>4) After joining the domain, I have different spn information for the 
>Windows host versus the Debian host:
># samba-tool spn list adtest$
>User CN=adtest,CN=Computers,DC=foobar,DC=ca has the following 
>	 HOST/adtest.foobar.ca
># samba-tool spn list windows81-vm$
>User CN=WINDOWS81-VM,CN=Computers,DC=foobar,DC=ca has the following 
>	 HOST/Windows81-VM.foobar.ca
>	 RestrictedKrbHost/Windows81-VM.foobar.ca
>	 RestrictedKrbHost/WINDOWS81-VM
>	 TERMSRV/Windows81-VM.foobar.ca
>Could it be that I somehow need to give permissions to my "adtest" 
>Debian host to be able to connect via Kerberos?
>5) Is it actually necessary to kinit as suggested elsewhere? It just
