    <p><strong>Problems:</strong></p> <ol> <li><p><strong>Explicit home directory:</strong> Your command line syntax is wrong. Try the following instead:</p> <p><code>sudo useradd -m username</code></p> <p>or</p> <p><code>sudo useradd -d /home/username -m username</code></p></li> <li><p><strong>Is PHP a sudoer?</strong> Only certain accounts are able to execute sudo. Check that the account PHP runs under is listed in the sudoers file. You can usually easily the file with</p> <p><code>visudo</code></p></li> <li><p><strong>Is PHP <code>chroot</code>-ed?</strong> If so, you may not be able to create new linux user accounts from scripts with any reasonable code.</p></li> </ol> <p><strong>A working test</strong></p> <p>The following worked for me under Debian (without sudo).</p> <p><em>newuser.sh</em></p> <pre><code>#!/bin/bash useradd -d /home/$1 -m $1 </code></pre> <p><em>newuser.php</em></p> <pre><code>&lt;?php exec('/bin/bash /var/www-scripts/newuser.sh joe'); ?&gt; </code></pre> <p><em>test invocation:</em> <code>php newuser.php</code></p> <p>If you can perform the same tests (but add sudo as needed), then the only reason it would not work when invoked by your web server is a security problem. That could either be a chroot environment, or lacking sudoer privilege.</p> <p><strong>Additional resources</strong></p> <p>You can see how other people have solved this problem by reviewing the following:</p> <ol> <li><a href="http://www.weberdev.com/get_example.php3?ExampleID=3766" rel="nofollow">http://www.weberdev.com/get_example.php3?ExampleID=3766</a></li> <li><a href="http://www.linuxforums.org/forum/programming-scripting/176031-solved-crafting-php-script-create-unix-user.html" rel="nofollow">http://www.linuxforums.org/forum/programming-scripting/176031-solved-crafting-php-script-create-unix-user.html</a></li> </ol>

    2. CO@misthe Have you confirmed that PHP runs under www-data? Sometimes PHP is configured to run under a different account for security reasons -- particularly if serving scripts from multiple users.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
