## Configuration

### OBM

To enable LL::NG authentication plugin, go in `/etc/obm/obm_conf.inc`:

    $auth_kind = 'LemonLDAP';

    $lemonldap_config = Array(
                    "auto_update"           => true,

            );

Parameters:

- url_logout: URL used by OBM to logout, will be caught by LL::NG

- headers_map: map OBM internal field to LL::NG header

Edit also OBM configuration to enable LL::NG Handler:

- For Apache:

    <VirtualHost *:80>
        ServerName obm.example.com

        # SSO protection
        PerlHeaderParserHandler Lemonldap::NG::Handler

        DocumentRoot /usr/share/obm/php

        ...

    </VirtualHost>

- For Nginx:

    server {
      listen 80;
      server_name obm.example.com;
      root /usr/share/obm/php;
      # Internal authentication request
      location = /lmauth {
        internal;
        include /etc/nginx/fastcgi_params;
        fastcgi_pass unix:/var/run/llng-fastcgi-server/llng-fastcgi.sock;
        # Drop post datas
        fastcgi_pass_request_body  off;
        fastcgi_param CONTENT_LENGTH "";
        # Keep original hostname
        fastcgi_param HOST $http_host;
        # Keep original request (LLNG server will received /llauth)
        fastcgi_param X_ORIGINAL_URI  $original_uri;
      }

      # Client requests
      location ~ \.php$ {
        auth_request /lmauth;
        set $original_uri $uri$is_args$args;
        auth_request_set $lmremote_user $upstream_http_lm_remote_user;
        auth_request_set $lmlocation $upstream_http_location;
        error_page 401 $lmlocation;
        try_files $uri $uri/ =404;

        ...

        include /etc/lemonldap-ng/nginx-lua-headers.conf;
      }
      location / {
        try_files $uri $uri/ =404;
      }
    }

### LL::NG

#### Attributes and macros

You will need to collect all attributes needed to create a user in OBM, this includes:

- First name

- Last name

- Login

- Mail

- …

To add these attributes, go in Manager, `Variables` » `Exported Variables`.

Attention

If you plan to forward user’s password to OBM, then you have to keep the password in session.

You may also create these macros to manage OBM administrator account (`Variables` » `Macros`):

field | value
--- | ---
uidR | `($uid =~ /^admin0/i)[0] ? "admin0\@global.virt" : $uid`
mailR | `($uid =~ /admin0/i)[0] ? "" : ($mail =~ / ([ @]+)/)[0] . "\@example.com"`

#### Virtual host

Create OBM virtual host (for example obm.example.com) in LL::NG configuration: `Virtual Hosts` » `New virtual host`.

Then edit rules and headers.

##### Rules

Define at least:

- Default rule: who can access to the application

- Logout rule: catch OBM logout

- Exceptions: allow anonymous access for specific URLs (connectors, etc.)

field | value
--- | ---
^/logout | logout_sso
^/obm-sync | unprotect
^/minig | unprotect
^/Microsoft-Server-ActiveSync | unprotect
^/caldav | unprotect
default | accept (or whatever you want)

##### Headers

Define headers used in OBM mapping, for example:

field | valeur
--- | ---
OBM_GIVENNAME | $givenName
OBM_GROUPS | $groups
OBM_UID | $uidR
OBM_MAIL | $mailR
OBM_USERPASSWORD | $_password

#### Other

Do not forget to add OBM in applications menu.
