Re: [Samba] wbinfo -U id gives different users on same dc




sure, 
 
https://github.com/thctlo/samba4/tree/master/howtos ;
now these are debian based, but if you read throught the howto. 
start with stretch-base-2.0-samba-minimal-ad.txt
 
ok, that happens that .local cant be changed, but now its even more important that the resolving is correct.
 
the hosts 
127.0.0.1 localhost localhost.localdomain 
10.254.104.8 wdc04.aa.local wdc04           < is this the samba DC? 
10.254.105.208 AA-SM2                            << missing .domain  or this, i "guess" base on you join below its this one. 
setup host like this.
IP     HOST_FQDN(hostname -f)    ALIAS_NAME(hostname -s) 



and /etc/resolv.conf


search aa.local                    < this is your primary samba domain. 
nameserver 10.254.104.8    < this is your dc? 
nameserver 10.254.104.13    and this is? 
 
i also suggest, goto 
https://wiki.archlinux.org/index.php/Samba/Active_Directory_domain_controller ;
some parts of my howto are also from arch examples.

Hi Louis,


Thanks for information, find it sometimes is a real challenge. Would you please share your how to link? I wish to read it. 

For the .local domain I suppose I have nothing to do. This is a running windows Active Directory and it is not possible to change domain suffix.


Here is my /etc/hosts


127.0.0.1 localhost.localdomain localhost
10.254.104.8 wdc04.aa.local wdc04
10.254.105.208 AA-SM2



and /etc/resolv.conf


search aa.local
nameserver 10.254.104.8
nameserver 10.254.104.13


My distribution is Archlinux.


Greetings,
Ozkan




Sure there is,
Install debian, follow my howto and you will have success.

Just, your using an .local domain, and thats a reserved name for apples mDNS (zeroconf)
And should not be used. ( same for .lan )
https://wiki.samba.org/index.php/FAQ#Can_I_Use_the_.local_Top-level_Domain_for_My_AD_DNS_Zone.3F
So the info is good, thats not the problem, finding it, is.

Can you post your /etc/hosts and resolv.conf also to be sure these are ok.
And whats the running OS, thats a nice to know.

Greetz,

Louis
