[Samba] authentication problems sernet-samba

[Lulzim KELMENI]

Hello, 

We have installed samba4 under Ubuntu 14.04.3 LTS. 

>
root at server:~# samba -V
> Version
4.2.3-SerNet-Ubuntu-7.trusty

Sometimes, we have authentication
problems. 

The only thing we found in log file, when it happend, is
this :
