How to install OX LDAP Sync
Debian
Add the following entry to /etc/apt/sources.list:
deb http://software.open-xchange.com/OX6/unsupported/repo/DebianEtch/ /
and run
$ apt-get update $ apt-get install oxldapsync
SLES10
Important: Some of the dependencies require SLES10 SDK
Run the following commands:
$ zypper sa http://software.open-xchange.com/OX6/unsupported/repo/SLES10 UNSUPPORTED $ zypper install oxldapsync
SLES11
Important: Some of the dependencies require SLES11 SDK
Run the following commands:
$ zypper ar http://software.open-xchange.com/OX6/unsupported/repo/SLES11 UNSUPPORTED $ zypper install oxldapsync
RHEL5
In order to install all required packages in RHEL, you need to add the EPEL repository.
$ rpm -Uhv http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
After you've done that, add the open-xchange unsupported repository:
$ vim /etc/yum.repos.d/unsupported.repo [unsupported] name=Open-Xchange Unsupported baseurl=http://software.open-xchange.com/OX6/unsupported/repo/RHEL5/ enabled=1 gpgcheck=0
Then run
$ yum update $ yum install oxldapsync
How to run OX LDAP Sync
With OX LDAP Sync you can sync user and group objects from a LDAP compatible directory with Open-Xchange. When you modify or add an user to your ldap directory oxldapsync will also modify or add the user to Open-Xchange.
Prerequisites
- An LDAP-server (currently openldap and ADS are supported)
- You need one user distinguished name who at least can search and read user objects. If you decide to synchronize groups, the ldap user needs to search and read these objects, too.
- If you want to synchronize groups you need to know if the membership to the group is defined by the userid or by the complete distinguished name of the user.
- User attributes you want to sync with Open-Xchange
- Open-Xchange must authenticate against the LDAP server instead of the database, which is the default. In order to achieve that, deinstall package open-xchange-authentication-database and install open-xchange-authentication-ldap and configure it accordingly in changing /opt/open-xchange/etc/groupware/ldap.properties. As an alternative, open-xchange-authentication-imap could be used, if your IMAP server authenticates against your LDAP server.
configuring OX LDAP Sync
After installing OXSync you will find the configuration files under /opt/oxldapsync/etc. You can use the example configuration files ldapsync.conf (openldap) and ldapsyn-ads.conf (Active Directory) as starting point.
OpenLDAP
Open ldapsync in your favourite text editor change following options to your needs:
ldapuri with dns-name or ip of your
LDAP-Server
userbasedn distinguished name under which the
script will find user objects
groupbasedn distinguished name under which the
script will find group objects
ldaptype type of ldap in this case openldap
ldapuserdn distinguished name of the user
which will be used to query the
directory
ldapuserpassword password for the ldapuser
mappingfile absolute path to your ldap
attribute -> ox attribute mapping
updategroups "yes" if you want to also sync
groups with ox
updateAlias shall mail aliases of a user get
updated with the one from the ldap.
In case you can name only one
mailaddress on your directory, say
no here and you can manually add
further mailaddresses in ox. They
will not get deleted by the
synctool.
usemodifytimestamp set to yes, to update only users
since last run
userfilter searchfilter to find user objects,
internal default
"(objectClass=inetOrgPerson)"
groupfilter searchfilter to find group objects,
internal default
"(objectClass=posixGroup)"
deleteusers Say yes if you want to delete users
in ox which are not in your
directory and are not named by the
"dontModifyUids" option
deletegroups say yes to delete empty and non
existing groups in ldap in ox
dontModifyUids list of comma separeted uid's which
shall not be modified by the sync
script. You should note at least
the contextadmin
groupMemberAttribute name of attribute which holds the
members in a group object
memberAttributeIsDN say yes if groupMemberAttribute is
a distinguished name
groupDisplayNameAttribute displayname attribute for group
groupNumberAttribute unique number attribute for group
userPrimaryGroupAttribute attribute name where a users primary
is stored
In the mapping file you will find ox options to create or modify users. The name on the left side of the equal sign is the name for the ox options. On the right side you name the ldap attribute name for this option. You can also give static values by enclosing them with qoutes.
Active Directory
For active directory synchronization just modify at least ldapuri, userbasedn, groupbasedn, ldapuserdn and ldapuserpassword.
To run the script type
$ /opt/oxldapsync/sbin/oxldapsync.pl -f <CONFIG FILENAME> \
-A <CONTEXT ADMIN USERNAME> \
-P <CONTEXT ADMIN PASSWORD> \
-c <CONTEXTID>
Additional parameters are:
-h help message
-n don't save last user search time
-v Verbose mode
-s print messages to stdout
To run this program regularly just create a cronjob
Troubleshooting
Special chars scrambled
If you run OX LDAP Sync via Cronjob an the umlauts (ä,ö,ü,...) of your entries in the "Global Addressbook" are scrambled, try setting the LANG environment variable in your crontab, e. g. German UTF-8 users should set this to something like this:
LANG=de_DE.UTF-8 #m h dom mon dow command 0 23 * * Sun /path/to/oxldapsync.pl
For more information on using the crontab please visit this howto at The Linux Documentation Project.
