## Get the packages

### Repositories

This manual only refers to SLES 12 SP1. Installation may work on other platforms, with no guarantee.

Different repositories are necessary for LemonLDAP::NG dependencies:

- Suse official repositories
- 2 repositories on OpenSuse Build Service
- Additional packages available on repository.linagora.org or lemonldap-ng.org
- Suse SDK repository is advised for building packages (yast2 → Software → Software Repositories → Add –> Extensions and modules from Registration Server)

First, make sure the exploitation system is up to date:

    zypper update

You can add the OpenSuse Build Service repositories with the following commands:

    zypper addrepo http://download.opensuse.org/distribution/leap/42.1/repo/oss/suse/ leap42
    zypper addrepo http://download.opensuse.org/repositories/devel:languages:perl/SLE_12/devel:languages:perl.repo
    zypper refresh

Accept both signing keys each time.

You can add the additional dependency repository *and* the LemonLDAP::NG repository with either commands:

    zypper addrepo http://lemonldap-ng.org/sles12 lemonldap-sles12-repository
    zypper refresh

or

    zypper addrepo http://repository.linagora.org/lemonldap-sles12-repository lemonldap-sles12-repository
    zypper refresh

Only packages on SLES 12 SP1 are tested for now.

### Manual download

RPMs are available on the Download page.

## Package GPG signature

The GPG key can be downloaded here: rpm-gpg-key-ow2

Install it to trust RPMs:

    rpm --import rpm-gpg-key-ow2

## Install packages

### With ZYPPER

If the packages are stored in a repository:

    zypper install lemonldap-ng

    59 new packages to install.
    Total download size: 13.5 MiB. Already cached : 0 B. After operation, 30.7 MiB of supplementary disk space will be used.
    Continue ? [y/n/? print all options] (y):

You can also use zypper on local RPMs file:

    zypper install lemonldap-ng-* perl-Lemonldap-NG-*

### With RPM

Before installing the packages, install all dependencies: (you need to get dependencies from previous repositories)

    zypper install apache2 apache2-mod_perl apache2-mod_fcgid perl-ldap perl-XML-SAX perl-XML-NamespaceSupport perl-XML-Simple perl-XML-LibXML perl-Config-IniFiles perl-Digest-HMAC perl-Crypt-OpenSSL-RSA perl-Authen-SASL perl-Unicode-String gd perl-Regexp-Assemble perl-Authen-Captcha perl-Cache-Cache perl-Apache-Session perl-CGI-Session perl-IO-String perl-MIME-Lite perl-SOAP-Lite perl-XML-LibXSLT perl-String-Random perl-Email-Date-Format perl-Crypt-Rijndael perl-HTML-Template perl-JSON perl-Crypt-OpenSSL-X509 perl-Crypt-DES perl-Class-Inspector perl-Test-MockObject perl-Clone perl-Net-CIDR-Lite perl-ExtUtils-MakeMaker perl-CGI perl-CGI-Session perl-HTML-Template perl-SOAP-Lite perl-IPC-ShareLite perl-Error perl-HTML-Parser perl-libwww-perl perl-DBI perl-Cache-Memcached perl-Class-ErrorHandler perl-Convert-PEM perl-Crypt-DES_EDE3 perl-Digest-SHA perl-Env perl-Mouse perl-String-CRC32 perl-Plack perl-Regexp-Common perl-Crypt-OpenSSL-Bignum perl-FCGI-ProcManager

You have then to install all the downloaded packages:

    rpm -Uvh lemonldap-ng-* perl-Lemonldap-NG-*

You can choose to install only one component by choosing the package `lemonldap-ng-portal`, `lemonldap-ng-handler` or `lemonldap-ng-manager`.

Install the package `lemonldap-ng-conf` on all server which contains one of those packages.

## First configuration steps

### Enable Apache extensions

These extensions are activated by default on Apache at LemonLDAP install:

    a2enmod perl
    a2enmod headers
    a2enmod mod_fcgid
    a2enmod ssl
    a2enmod rewrite
    a2enmod proxy
    a2enmod proxy_http

If you decide to use SSL, you should also activate the appopriate flag:

    sed -i 's/^APACHE_SERVER_FLAGS=.*/APACHE_SERVER_FLAGS="SSL"/' /etc/sysconfig/apache2

### Change default DNS domain

By default, DNS domain is `example.com`. You can change it quick with a sed command. For example, we change it to `ow2.org`:

    sed -i 's/example\.com/ow2.org/g' /etc/lemonldap-ng/{*.conf,*.ini,for_etc_hosts} /var/lib/lemonldap-ng/conf/lmConf-1 /var/lib/lemonldap-ng/test/index.pl

Check Apache configuration and restart:

    apachectl configtest
    apachectl restart

### Reload virtual host

To allow the manager to reload the configuration, register the reload virtual host name in the hosts of the server:

    echo "127.0.0.1 reload.example.com" >> /etc/hosts

Adapt the reload virtual host name to the domain you configured.

### Upgrade

If you upgraded LL::NG, check all upgrade notes.

For apache configuration, you may have to remove the old symbolic link, if not done by the RPM:

    rm -f /etc/apache2/vhosts.d/z-lemonldap-ng.conf

Your old Apache configuration should have been saved, you need to port your specificities in new Apache configuration files:

    vi /etc/lemonldap-ng/apache2.conf.rpmsave

The upgrade process will also have migrate old configuration files into `/etc/lemonldap-ng/lemonldap-ng.ini`. This includes the application list which is now set in the `applicationList` parameter from `[portal]` section, for example:

    [portal]
    applicationList={ 'Menu' => { type => 'category', 'Example' => { type => 'category', 'test1' => { type => 'application', options => { name => 'Application Test 1', uri => 'http://test1.example.com/', description => 'A simple application displaying authenticated user', logo => 'wheels.png', display => 'auto',  }, },'test2' => { type => 'application', options => { name => 'Application Test 2', uri => 'http://test2.example.com/', description => 'The same simple application displaying authenticated user', logo => 'wheels.png', display => 'auto',  }, }, },'Administration' => { type => 'category', 'manager' => { type => 'application', options => { name => 'WebSSO Manager', uri => 'http://manager.example.com/', description => 'Configure LemonLDAP::NG WebSSO', logo => 'tools.png', display => 'on',  }, },'sessions' => { type => 'application', options => { name => 'Sessions explorer', uri => 'http://manager.example.com/sessions.pl', description => 'Explore WebSSO sessions', logo => 'tools.png', display => 'on',  }, }, },'Documentation' => { type => 'category', 'localdoc' => { type => 'application', options => { name => 'Local documentation', uri => 'http://manager.example.com/doc/', description => 'Documentation supplied with LemonLDAP::NG', logo => 'docs.png', display => 'on',  }, },'officialwebsite' => { type => 'application', options => { name => 'Offical Website', uri => 'http://wiki.lemonldap.objectweb.org/xwiki/bin/view/NG/Presentation', description => 'Official LemonLDAP::NG Website', logo => 'web.png', display => 'on',  }, }, }, }, }

You should now use the Manager to configure all applications and categories, and then comment or remove the `applicationList` parameter from `/etc/lemonldap-ng/lemonldap-ng.ini`.

### DNS

Configure your DNS server to resolve names with your server IP.

For tests with `example.com`, launch the following :

    cat /etc/lemonldap-ng/for_etc_hosts >> /etc/hosts

Follow the next steps

## File location

- Configuration is in /etc/lemonldap-ng
- LemonLDAP::NG configuration (edited by the Manager) is in /var/lib/lemonldap-ng/conf/
- All Perl modules are in the VENDOR perl directory
- All Perl scripts/pages are in /var/lib/lemonldap-ng/
- All static content (examples, CSS, images, etc.) is in /usr/share/lemonldap-ng/

## Build your packages

If you need it, you can rebuild RPMs:

- Install rpm-build package
- Get the lemonldap source package from repository:

    zypper source-install lemonldap-ng
    cd /usr/src/packages/
    ls SPECS/ SOURCES/

- Install all build dependencies (see BuildRequires in lemonldap-ng.spec)
- Build:

    rpmbuild -ba SPECS/lemonldap-ng.spec

Alternatively, you can use the automatic script “create-lemonldap-packages.sh”, available in rpm-sles directory in the lemonldap svn repository. The automatic script can also generate intermediate dependencies. See README file in the same directory for more information.
