Re: [Samba] DM: samba 4.5 -> 4.8, guest access and machine account access troubles.




Hai Marco, 

Few pointers. 
First, time is in sync? I guess it is, but check it.

Second. 
Guest access enabled on a domain joint PC ? 
If you really really want that, then enable user guest in the AD also. 

But better is avoiding Guest access completely. 
Join the domain, dont allow guest access and configure it correctly, 
best tip i can give, for the software deploying share. 

  [wpkg]
 	path = /srv/samba/wpkg
 	browseable = No
 	comment = WPKG Automated Software Deploying System
	acl_xattr:ignore system acls = yes
	acl_xattr:default acl style = windows
 	wide links = Yes


Now setup the share from a windows client. 
On the Share tab: activate sharing. 
- Allow read access to that share for the special group "Domain Computers", or to everyone, and write access for yourself.
- On the Security tab: grant read access to the special group "Domain Computers", or to everyone, and write access for yourself.

And try again. 

Greetz, 

Louis
