[Samba] Problem with Winbind and Windows Clients

Tue Mar 15 10:10:33 UTC 2016

Ok, next test. 

Change :
kerberos method = secrets and keytab 
to 
kerberos method = secrets

and wait again. 

I'll explain by giving this link. 
http://changelogs.ubuntu.com/changelogs/pool/main/s/samba/samba_4.3.6+dfsg-1ubuntu1/changelog 

Look at the last line bugfix in this change log of 4.3.6.
Im testing here also, because this looks like its also involves the kerberos changes, now, i forgot what you was running, but this is an easy test. 

Is ntp installed on this machine, if not, install it and point it to the DC. 
Just to be sure. 
On the DC's, make sure your DC dont use any pool ntp servers. 
Point it to a stable ntp. ( preffered in germany, like, ntps1-0.eecsit.tu-berlin.de (130.149.17.21) )

Greetz, 

Louis
