[Samba] authentication problems sernet-samba

Hello L.P.H, 

The "Wait for Network" policy is already set and
applied to all domain computers. 

By the way, when we restart samba
(service sernet-samba-ad restart) GPO are applied and users can connect
without problem and the strange logs stop in /var/log/samba/log.samba

[Samba] authentication problems sernet-samba

It this a test environment ? 

...  dctest.local 

Dont use .local reserved name of apples mDNS.  

Remove avahi from your server. 
Recheck nsswitch.conf so it starts like : passwd:         compat winbind 
( so if needed change the order ) 

Recheck you resolv.conf 
Should be : 
Search dominname 
Nameserver IP_DC1

And i you have itunes on your pc, remove it. 
And try again, this is not a samba problem but a configuration problem. 


Greetz,

[Samba] authentication problems sernet-samba

No, it is in production, i just change the real domain name by
DCTEST for confidentiality. 

*Avahi is not installed in our server
(print server is in an other server) 

*resolv.conf is good. 

* I read
the documentation here
https://wiki.samba.org/index.php/Setup_a_Samba_Active_Directory_Domain_Controller
[1] , and i can't find where it is said to modify the nsswitch.conf in
a server which is ONLY domain controller. We have modified it in an
other ubuntu server (the domain member) as descibed here
https://wiki.samba.org/index.php/Setup_a_Samba_AD_Member_Server [2]


*We have not iTunes installed in our PC. 

When this problem occurs,
no computer can authenticate in the domain (we have actually 170 PC in
the domain and it will soon grow to 700). The only solution is to
restart samba. I can NOT reproduce the problem : i have to wait until it
occurs. This authetication problem happend 7 times from 04/06/2015 until
now.
