<header>User ID</header>
|
|
The user ID or UID is what the system really uses to enforce permissions
|
|
on files and processes. If two users have the same UID, they will be able
|
|
to access each others files - so every user should have a unique UID.<p>
|
|
|
|
When creating a new user, you will have the following options:
|
|
<dl>
|
|
<dt>Automatic
|
|
<dd>The UID will be assigned automatically by Webmin, based on those currently in use.
|
|
<dt>Calculated
|
|
<dd>The UID will be computed based on the username, using a checksum algorithm.
|
|
<dt>Entered
|
|
<dd>The final option allows you to enter whatever UID you like.
|
|
</dl><p>
|
|
|
|
The <tt>root</tt> user always has a UID of 0. If you create another user
|
|
with UID 0, that user will have the same powers as <tt>root</tt>. <p>
|
|
|
|
If you are editing an existing user and change the UID, the
|
|
<a href=chuid>Change user ID on files?</a> option determines which files
|
|
(if any) have their ownership changed. <p>
