Local users can also be individually exempted from password expiration and character
requirement policies. The built-in admin user is exempt from all password policies.

UID and GID Assignments

The SnapServer uses the POSIX standard to assign UIDs or GIDs, in which each user and
group must have a unique ID. This requirement applies to all users and groups on the
SnapServer, including local, Windows, and NIS users and groups.
If you join the SnapServer to a Windows or NIS domain, IDs are assigned using available
IDs only. Consider the following when creating users and groups:
• UIDs and GIDs from 0 to 100 are unavailable for use. If you try to assign a UID or
GID that is less than 101 (or in use by NIS or the Windows domain), you will get an
error message.
• When the server automatically generates UIDs or GIDs for imported Windows
domain users or groups, UIDs or GIDs that are already in use by local and NIS users
will be skipped.
• When NIS domain users and groups are imported, the SnapServer will discard any
UIDs that are less than 101 or are in conflict with UIDs already in use by local or
Windows domain users and groups.

GuardianOS offers ID Mapping, which allows mapping of Windows users to local or NIS
users to provide unified permission assignments to users of different protocols. For more
