<div style="text-align: center;"><br>
 |

<div style="text-align: left;">The <span style="font-style: italic;">login</span>
 | 
						|
page is the first page the user sees when opening LAM. It manages LDAP
 | 
						|
authentication and checks the environment of the user.<br>
 | 
						|
<br>
 | 
						|
<br>
 | 
						|
<h2>login.php</h2>
 | 
						|
The login page offers authentication, language selection and profile
 | 
						|
selection. There are also some environment checks.<br>
 | 
						|
<br>
 | 
						|
<h3>Authentication</h3>
 | 
						|
The list of possible users is loaded from the current active profile.
 | 
						|
Only the RDN value is offered for selection by the user.<br>
 | 
						|
When the user submits his password then a new <span
 | 
						|
 style="font-style: italic;">Ldap</span> object is created and LAM
 | 
						|
tries to connect to the LDAP server.<br>
 | 
						|
If the connection was successful the user is forwarded to the main
 | 
						|
frame (main.php). The session variable <span
 | 
						|
 style="font-weight: bold; font-style: italic;">$_SESSION['loggedIn']</span>
 | 
						|
is set to <span style="font-style: italic;">true</span>. This informs
 | 
						|
the other PHP scripts that a valid user is connected (e.g. the user is
 | 
						|
allowed to create account profiles).<br>
 | 
						|
<br>
 | 
						|
<h3>Language selection</h3>
 | 
						|
The list of possible languages is read from <span
 | 
						|
 style="font-weight: bold;">config/language</span>. The current active
 | 
						|
profile defines the preselected language and the language of the login
 | 
						|
page itself.<br>
 | 
						|
<br>
 | 
						|
<h3>Profile selection<br>
 | 
						|
</h3>
 | 
						|
The user can change the active configuration profile at login. A list
 | 
						|
of possible profiles is retrieved by <span
 | 
						|
 style="font-weight: bold; font-style: italic;">getConfigProfiles()</span>.<br>
 | 
						|
If the profile is changed then the login replaces the config object in <span
 | 
						|
 style="font-weight: bold; font-style: italic;">$_SESSION['config']</span>
 | 
						|
by a new one. Then the main login page is loaded and uses the new
 | 
						|
values.<br>
 | 
						|
<br>
 | 
						|
<h3>Environment checks</h3>
 | 
						|
LAM checks if all needed PHP extensions are installed.<br>
 | 
						|
<ul>
 | 
						|
  <li><span style="font-weight: bold;">LDAP:</span> PHP needs LDAP
