OS4X Core web interface

Configuration

The OS4X web interface uses the global OS4X configuration file "/etc/os4x.conf". This file is expected in exactly this location. If this is not the case in your environment, please contact OS4X support at contact@os4x.com.

Securing with password

The easiest way to secure the OS4X administrative web interface in an Apache environment is to use the authentification method via ".htaccess". There areseveral options available, the two most common ways are shown here.

Securing with given username and password

In the web interface directory (i.e. /var/www/os4x) create a textfile named ".htaccess" with this content:

AuthUserFile /var/www/os4x/.htpasswd
AuthName "OS4X"
AuthType Basic
require valid-user

The path of the "AuthUserFile" should be changed to your OS4X administrative web interface directory.

Then, you have to create the authentification file using the external tool "htpasswd" and add user(s) to that file. In order to create this user file, use it as follows:

os4x@os4xbox:/var/www/os4x$ htpasswd -c /var/www/os4x/.htpasswd os4x
New password:
Re-type new password:
Adding password for user os4x

("os4x" is the username). You can add users to the given password file subsequently by calling this program without the parameter "-c":

os4x@os4xbox:/var/www/os4x$ htpasswd /var/www/os4x/.htpasswd username2
New password:
Re-type new password:
Adding password for user username2

Securing with LDAP / ActiveDirectory

If you have an LDAP based directory service available (i.e. openLDAP, Microsoft Active Directory, IBM Lotus Notes etc.) you can authenticate users via your centralized user storage.

Requirements:

• Apache module "ldap" is either compiled in or loaded as module:

LoadModule ldap_module /usr/lib/apache2/modules/mod_ldap.so

• Apache module "authnz_ldap" is either compiled in or loaded as module:

LoadModule authnz_ldap_module /usr/lib/apache2/modules/mod_authnz_ldap.so

Example configuration file in web interface directory (i.e. /var/www/os4x) named ".htaccess":

AuthType Basic
AuthName Internal
AuthBasicAuthoritative off
AuthBasicProvider ldap
AuthzLDAPAuthoritative off
AuthLDAPURL ldap://192.168.0.1/OU=ou-os4x-admin,DC=de,DC=company,DC=net?sAMAccountName??(objectclass=*)
require valid-user
AuthLDAPBindDN "CN=os4x,OU=admins,OU=ou-admins,DC=de,DC=company,DC=net"
AuthLDAPBindPassword "pwd"

Explanation of the configuration variables:

• AuthLDAPURL: defines the connectivity of the LDAP server via IP address or hostname, also contains the information where to search for valid users
• AuthLDAPBindDN: configuration of the connecting user who has the permission to search for the given user
• AuthLDAPBindPassword: password of the connecting user defined at "AuthLDAPBindDN"

If you want to allow only a list of special usernames (i.e. "username1", "username2" and "username3"), the line starting with "require " must contain a white-space separated list of these allowed usernames:

require user username1 username2 username3
