Re: [Samba] GPO / Sysvol problems




Hi Gregory, 

I see few things, start here : 
from smb.conf remove : map to guest = Bad User 
This enabled on a domain member or other domain server is really a no go. 
This makes debugging really hard. 

interpret_string_addr_internal: getaddrinfo failed for name 
> freenas.ad.abc.local (flags 1026) [hostname nor servname 
> provided, or not known]
Looks like there are resolving problems. 

On the server run : 
Command		result. 
hostname -s 	hostname
hostname -f		hostname.fqdn.tld
hostname -d		fqdn.tld

Check /etc/resolv.conf should look bit like this.: 
search ad.abc.local
nameserver ip_of_DC


/etc/hosts  should contain 
127.0.0.1	localhost
Ip_server 	hostname.fqdn.tld hostname

These need to be fixed first before you can even look at the profile problems.

Try above, if its not working, show the log also again. 
I've not talked about this part yet.

This "computer" gets a homedir?

A "about same problem" 
https://lists.samba.org/archive/samba/2018-October/219106.html 

His solution.
I restarted the setup with this documentation 
https://www.tecmint.com/install-samba4-active-directory-ubuntu/ . The 
problem was that pam was badly set and could not recognize samba users. 
For example: id Administrator, did not recognize by the user.  

BIG NOTE HERE: id Administrator should NEVER work. 
Yes its possible, but thats a complete different config and not supported. 
Why id Administrator should never work, because Administrator = root = 0 

Which samba version where you running.
It looks a bit like : https://forge.univention.org/bugzilla/show_bug.cgi?id=34973 

For me, this looks like a problem due to resolving issues. 
That needs to be fixed first.
