ID Mapping
102 SnapServer Administrator Guide
ID Mapping
ID mapping allows users and groups that exist on Windows domains to share user
IDs with local or NIS users and groups. This results in the same permissions and
quota consumption applying to both the Windows domain user and the local or NIS
user. Example:
John Smith is a local user on a SnapServer, as well as having a user ID on a
Windows domain. John’s quota for the SnapServer has been set to 200 MB. The
administrator of the SnapServer maps the Windows domain user identification
for John Smith to the local identification for John Smith, giving both IDs access to
John’s 200 MB.

System
Permissions
Security model and permissions differ according to the method used to
create the SnapTree directory:
• From the client: If SMB, permissions will either be according to ACL
inheritance (if the parent volume root directory has the Windows
security model) or
Full Access
to the owning user only. Permissions for
directories created by all other protocols will be set by the client (per
the client’s umask).
• From the Administration Tool: If created in a UNIX volume, permissions
will be
777
(rwxrwxrwx). If created in a Windows/Mixed volume,
permissions will allow all users to create, delete, and change
permissions on files created inside the SnapTree, and will grant full
control to administrators.

Security
Models
Changes to a SnapTree’s security model can optionally be propagated to
the corresponding personality with a default permission to all files and
directories underneath the SnapTree.
When changing the security model on a SnapTree:
• If changing from Windows to UNIX, all files and directories will be
changed to be owned by
admin
and
admingrp
, with UNIX permissions
of 777(rwxrwxrwx).
• If changing from UNIX to Windows, files and directories will be
changed to default permissions that allow all users the ability to create
and manage their own files and directories and to access other users’
files and directories.
Mixing
SnapTrees
You can create SnapTrees of different security models on the same
volume.
