NAME

Wizard::LDAP - Administration interface for your LDAP server

SYNOPSIS

  # From the shell:
  ldapWizard

  # Or, from the WWW:
  <a href="ldap.ep">LDAP administration</a>

DESCRIPTION

This is a package for administration of an LDAP server. It allows to feed users, hosts and networks into the server.

INSTALLATION

First of all, you have to install the prerequisites. There are lots of:

An LDAP Server

You need some LDAP server. We are using the OpenLDAP server, see

  http://www.openldap.org/

In theory any other LDAP server should do, but the servers configuration might be different.

A source RPM for Red Hat Linux is available on demand.

To configure the LDAP server, edit the file topics.ldif from the distribution. Currently it looks like

  dc=ispsoft, dc=de
  objectclass: organization
  o: My Organization Name

  dn: topic=user, dc=ispsoft, dc=de
  name: user 
  objectclass: topic

  dn: topic=net, dc=ispsoft, dc=de
  name: net 
  objectclass: topic

Change "dc=ispsoft, dc=de" and the organization name to reflect your local settings. For example, if you are using the mail domain "mycompany.com", then you might choose

  dc=mycompany, dc=com

Import the file into your LDAP server by using the command

  ldif2ldbm -i topics.ldif

(The above command will trash an existing LDAP database! Use ldapadd if you want to avoid this.)

Append the files slapd.at.conf.APPEND and slapd.oc.conf.APPEND to your /etc/openldap/slapd.at.conf and /etc/openldap/slapd.oc.conf and restart the OpenLDAP server.

IO::AtomicFile

This is a Perl package for atomic operations on important files.

HTML::EP

If you like to use the WWW administration interface, you need the embedded Perl system HTML::EP.

Wizard

Another Perl module, available at the same place.

Convert::BER
Net::LDAP

To talk to the LDAP server, we use Graham Barr's Net::LDAP package. It is written in 100% Perl, no underlying C library required.

Net::Netmask

Used to determine conformance of host IP´s to a network.

All the above packages are available on any CPAN mirror, for example

  ftp://ftp.funet.fi/pub/languages/perl/CPAN/authors/id

or perhaps at the same place where you found this file. :-)

Note that some of the packages have their own requirements. For example, HTML::EP depends on libwww and the MailTools. If so, you will be told while installing the modules. See below for the installation of the Perl modules.

Installing the Perl modules

Installing a Perl module is always the same:

  gzip -cd Wizard-LDAP-0.1005.tar.gz | tar xf -
  cd Wizard-LDAP-0.1005
  perl Makefile.PL
  make
  make test
  make install

Alternatively you might try using the automatic installation that the CPAN module offers you:

  perl -MCPAN -e shell
  install Bundle::Wizard::LDAP

Note that some of the modules, in particular HTML::EP, need additional configuration tasks, for example modifying the web servers configuration files.

Some final tasks

You have to create a directory /etc/Wizard-LDAP and make it owned by the httpd user, so that CGI binaries can write into this directory.

Copy the file ldap.ep and the file gethelp.ep from the Wizard distribution into your web servers root directory. (I choose /home/httpd/html/admin/ldap.ep on my Red Hat Linux box.)

Point your browser too the corresponding location, for example

  http://localhost/admin/ldap.ep

Start with modifying the preferences. See "THE LDAP-WIZARD PREFERENCES".

THE LDAP-WIZARD PREFERENCES

The system wide preferences are accessible via the web form ldap.ep. The following items can be configured:

item_ldap_prefs_serverip

This is the IP address of the LDAP server being used, typically

  127.0.0.1.

No default is set.

item_ldap_prefs_serverport

Likewise, this is the LDAP servers port number. The default is

  389

item_ldap_prefs_adminDN

This is the distinguished name to use for accessing the LDAP server as root. No default is set. Example:

  cn=root, dc=ispsoft, dc=de

item_ldap_prefs_adminPassword

This is the password to use for binding to the LDAP server as root. Currently the password *must* be stored in clear text. (This is subject to change.)

item_ldap_prefs_nextuid

This the next numeric UID, that will assigned to a new user. By default the value

  500

is choosen. The value is incremented with any new user, so after inserting the next users it will be 501, 502, 503 and so on. You typically should reserve some block of Unix UID's for users managed by the LDAP server.

item_ldap_prefs_gid

This is the numeric GID, that your LDAP users will have under Unix. The default is

  500

item_ldap_prefs_home

This is the prefix to use for the users home directories, for example

  /home

(the default). The users login names will be appended.

item_ldap_prefs_userbase

This is a suffix for constructing the distinguished names of your users. Example:

  dc=ispsoft, dc=de

item_ldap_prefs_netbase

A similar suffix for constructing the distinguished names of nets. Example:

  dc=ispsoft, dc=de

item_ldap_prefs_domain

The mail domain appended to unclassified email adresses. For example, if you have a user "joe" and the domain is "ispsoft.de", then its email adress will be joe@ispsoft.de.

item_ldap_prefs_prefschange

If you enter a shell command here, then this command will be launched after any change of the preferences. Example:

  /usr/bin/ldapAdmin --prefs

item_ldap_prefs_hostchange

This is a similar shell command that will be called after hosts have changed. Example:

  /usr/bin/ldapAdmin --hosts

item_ldap_prefs_netchange

A shell command to issue after network definitions have changed. Example:

  /usr/bin/ldapAdmin --nets

item_ldap_prefs_userchange_new

This is a special case of the command for changing users. If defined, it will be issued after a user was created. The users name will be appended as the last argument. If not defined, the above and more generic command will be executed.

item_ldap_prefs_userchange_modify

Similar to item_ldap_prefs_userchange_new, but for modified users. Again, the users name will be appended as a last argument.

item_ldap_prefs_userchange_delete

Finally a shell command being executed after a user has been deleted. The users name will be appended as a last argument.
