| -l,--local [machine] Print local user accounts of \"machine\", |

| -p,--path-to-home path Use specified path instead of user account home dir |

| -U,--unix userlist Print UNIX users when using -l on a UNIX Samba |

| Default is to print local accounts on stand-alone machines, domain accounts |
| on domain controllers and domain member machines. |
| </pre></div><div class="refsect1"><a name="mkpasswd-desc"></a><h2>Description</h2><p>Don't use this command to generate a local /etc/passwd file, unless you |
| really need one. See the Cygwin User's Guide for more information.</p><p>The <span class="command"><strong>mkpasswd</strong></span> program can be used to create a |
| <code class="filename">/etc/passwd</code> file. Cygwin doesn't need this file, |
| because it reads user information from the Windows account databases, |
| but you can add an <code class="filename">/etc/passwd</code> file, for instance |
| if your machine is often disconnected from its domain controller.</p><p>Note that this information is static, in contrast to the information |
| automatically gathered by Cygwin from the Windows account databases. If |
| you change the user information on your system, you'll need to regenerate |
| the passwd file for it to have the new information.</p><p>By default, the information generated by <span class="command"><strong>mkpasswd</strong></span> |
| is equivalent to the information generated by Cygwin itself. The |
| <code class="literal">-d</code> and <code class="literal">-l/-L</code> options allow you to |
| specify where the information comes from, some domain, or the local SAM |
| of a machine. Note that you can only enumerate accounts from trusted |
| domains. Any non-trusted domain will be ignored. Access-restrictions |
| of your current account apply. The <code class="literal">-l/-L</code> when used |
| with a machine name, tries to contact that machine to enumerate local |
| groups of other machines, typically outside of domains. This scenario |
| cannot be covered by Cygwin's account automatism. If you want to use |
| the <code class="literal">-L</code> option, but you don't like the default |
| domain/group separator from <code class="filename">/etc/nsswitch.conf</code>, |
| you can specify another separator using the <code class="literal">-S</code> option, |
| analog to <span class="command"><strong>mkgroup</strong></span>.</p><p>For very simple needs, an entry for the current user can be created |
| by using the option <code class="literal">-c</code>.</p><p>The <code class="literal">-o</code> option allows for special cases (such as |
| multiple domains) where the UIDs might match otherwise. The |
| <code class="literal">-p</code> option causes <span class="command"><strong>mkpasswd</strong></span> to use |
| the specified prefix instead of the account home dir or <code class="literal">/home/ |
| </code>. For example, this command: |
| </p><div class="example"><a name="utils-althome-ex"></a><p class="title"><b>Example 3.10. Using an alternate home root</b></p><div class="example-contents"><pre class="screen"> |
| <code class="prompt">$</code> <strong class="userinput"><code>mkpasswd -l -p "$(cygpath -H)" > /etc/passwd</code></strong> |
| </pre></div></div><br class="example-break"><p> |
| would put local users' home directories in the Windows |
| 'Profiles' directory. The <code class="literal">-u</code> option creates just an |
| entry for the specified user. The <code class="literal">-U</code> option allows you |
| to enumerate the standard UNIX users on a Samba machine. It's used |
| together with <code class="literal">-l samba-server</code> or <code class="literal">-L |
| samba-server</code>. The normal UNIX users are usually not enumerated, |
| but they can show up as file owners in <span class="command"><strong>ls -l</strong></span> output. |
