Here you have the permissions that Zentyal configures for a shared resource.
root@zen6:~# getfacl /home/samba/shares/sistemas/
getfacl: Removing leading '/' from absolute path names
# file: home/samba/shares/sistemas/

You can see how (in addition to the ACLs) the unix permissions system grants rwx access on /home/samba folder to the 'root' user and the domain users. In addition the /home/samba/shares/sistemas grants access to the domain administrator and the local group 'adm'.
You will should enable the Zentyal root user and add it to the adm group (however you'll have issues with the suse file owners, etc due to the acl's on Zentyal...)
I think that your best option could be to upload the resources from SUSE to Zentyal in your administrative user home in order to migrate them to the shared resource created through webadmin
(Zentyal will not recognizes it if you create the resource "manually") a
fter the creation of the domain user accounts of the files and folders owners you have to grant access to the resource (through webadmin too)If you makes a list of the owners of the files on SUSE you could make easily a bash script in order to transfer the ownership of each one of the files and folder to the correspondant users of your new domain after copying all of them on the shared resource with a domain user with rwx permissions on the shared resource.
I don't know if I have understood your problem correctly now.
PS: Tell me if you need some help with this process.
Cheers!
