Eine Besonderheit fällt auf: Wenn für den Nutzer im Open-Directory über den Arbeitsgruppenmanager verschiedene Kurznamen (Reiter »Allgemein«) für einen Nutzer vergeben wurden, werden diese im Attribut uid gespeichert. Dies führt dazu, dass der LDAP-Nutzer auf der Synology unter dem letzten Kurznamen in der Liste auftaucht. Ist der normale Nutzer-Account z.B. user1 und dessen letzte Kurzname Vorname.Nachname so taucht dieser User als Vorname.Nachname@ldap.domain.tld auf.

This guide is straight forward and shows just the required changes, a working MacPorts installation with Apache 2 is mandatory. You simply have to edit the Portfile that contains the details for mod_security.

Step-by-step explanation

1. Update your MacPorts installation by sudo port selfupdate and sudo port upgrade outdated (read this guide for more details on MacPorts selfupdate)
2. Open the portfile for mod_security and replace the content of the file with the provided code. The portfile in my installation resides in/opt/local/var/macports/sources/rsync.macports.org/ release/ports/www/mod_security/Portfile


   
   Download the Portfile as text file
   

3. Now you may install mod_security via MacPorts using this terminal command:sudo port install mod_security

4. Open the Apache configuration file (/opt/local/apache2/conf/httpd.conf) in a text editor and add mod_security to the list.Open a new Terminal (the Termin.app resides in /Applications/Utilities on your harddrive) window and then type the following command to open and edit the file (the sudo command is required to get write-access to this file since it is normally not writable for you user account).sudo nano /opt/local/apache2/conf/httpd.confNow enter your password (the same you use to log in to your Mac). Use the cursor keys to scroll down to the section for the Dynamic Shared Object (DSO) Support and copy the following line below the last LoadModule… statement (see screenshot).LoadModule security2_module modules/mod_security2.so
   

   To save and leave the Nano editor press CTRL+X and confirm with Y (for Yes) to save.

5. Reload the Apache server. The security module should now be loaded by Apache (start or restart Apache to commit changes).sudo /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper restart
