[Samba] samba AD, keberos, NFS - not working

[L.P.H. van Belle]

Hai, 

What is the debian your running Stretch? 
I'll guess Stretch. 

I can see i should work fine on stretch.

Can you post the output of 

cat /etc/idmap.conf
cat /etc/krb5.conf
klist -ke|sort

Which spn's are set and how did you set these. 

If you use automounting. 
You might want to try adding : 
[libdefaults]

    ignore_k5login = true


But first more info. 

And test a mount with -vvv and show that output. 


Greetz,
