Windows ACLs

Chapter 6  Share and File Access

107

Home directories are supported for SMB, NFS, AFP, HTTP/HTTPS, and FTP/FTPS. 

They are accessed by clients in the following manner:
• For SMB, AFP, and HTTP/HTTPS, users are presented with a virtual share 

named after the username. The virtual share is visible and accessible only to the 

user. Users are not limited only to their virtual shares; all other shares on the 

server continue to be accessible in the usual fashion.

• For NFS, the home directory is exported. When a user mounts the home directory 

root, all home directories will be visible inside the root, but the user’s home 

directory will be accessible only by the user and the administrator.

Note  

If desired, UNIX clients can be configured to use a Snap Home Directory as 

the local user’s system home directory. Configure the client to mount the home 

directory root for all users, and then configure each user account on the client to 

use the user-specific directory on the SnapServer as the user’s home directory.

• For FTP/FTPS, local users will automatically be placed in their private home 

directory when they log in. Access to the home directory is facilitated through a 

share pointing to a parent directory of the home directory, so users can still 

change to the top-level directory to access other shares.

If ID Mapping is enabled, domain users and local users mapped to the same user 

will be directed to the domain user’s home directory.  In some cases, data in the 

local user's home directory will be copied to the domain user's home directory:
• If a local user home directory accumulates files before the local and domain users 

are mapped, and if the domain user's home directory is empty, the local user's 

files will be copied to the domain user's home directory the first time the local 

user connects after the users are mapped.

• If both the local and domain user home directories accumulate files before the 

local and domain users are mapped, the files in the local user's home directory 

will not be copied to the domain user's home directory.

Windows ACLs  

Introduced in v5.0, GuardianOS now fully supports Windows NTFS-style file 

system ACLs, including configuration, enforcement, and inheritance models. Inside 

Windows/Mixed SnapTrees, files created and managed by Windows clients have 

the Windows security personality and behave just as they would on a Windows 

server. Clients can use the standard Windows NT, 2000, 2003, XP, Vista or Windows 

7 interface to set directory and file permissions for local and Windows domain users 

and groups on the SnapServer. 
Permissions are enforced for the specified users in the same manner for all client 

protocols, including non-SMB clients that normally have the UNIX security 

personality. However, if a non-SMB client changes permissions or ownership on a
