Openmediavault LDAP

This plugin connects OMV5 to an OPEN-LDAP Server for centralized user management and authentification. It adapts the official LDAP plugin [1] for OMV4 to use it with OMV5.
Basically there aren't any fundamental changes up to 5.3.9-r1 tag. You can use LDAP for system wide User- and Groupmanagement. Additionally you can activate PAM auth with libpam-ldapd module. The name switch service is done with libnss-ldapd. For caching actually the NSCD service is used, maybe we should change from NSLCD to SSSD in future. A good explanation of the pam auth and nss process will give you the reference [4].
This repo is under development. Checkout the tags in the master branch for stable and tested releases. If you encounter some problems make a new issue or write an email to devel[at]nareo.de.
Be aware: This code was tested in a clean environment with fresh installed OMV5 setup. I am not responsible for loss of your data! Please make always a full backup of your OMV machine before installing this plugin!

Build DEBIAN package

Create DEB package with dpkg-buildpackage -uc -us inside the source directory. The *.deb file will be placed in the parent directory.

Install Plugin into Openmediavault 5

Upload the generated *.deb file to OMV5 plugins and install it. Once it is installed, you have an additional menu item for LDAP Server settings.

Testing Environment and Help

The directory .test contains some basic config files for test environment with OMV5. I need someone to test with other LDAP services.

Environment:

• Openmediavault 5.5.9-1 (Usul) with running SAMBA service
• OpenLDAP 2.4.47 server (setup with smbldap-populate)
• all smbldap-tools 0.9.9-1 installed on OMV5

If you get in trouble, try:

• update system with apt-get update and apt-upgrade
• remove all uploaded packages via omv-firstaid tool
• remove plugin and reinstall
• change plugin settings
• get omv ldap config with omv-confdbadm read "conf.service.ldap"
