For use with Spacenet we've installed OpenLDAP on NURDServer. On the new Nurdserver v2 we're going serious with LDAP.
Working implementations on Nurdserver v1 (nurdserver)
- Samba on NURDServer
- vsFTPd on NURDServer
Working implementations on Nurdserver v2 (nurdservices)
- NFS export for homedirs
- Spacenet
Connected workstations
Status
FusionDirectory is running on a new VM called NURDserver_v2#nurdservicesnurdservices on the proxmox system of Nurdserver v2. Most users are migrated.
It can be accessed on http://nurdservices/fusiondirectory from within the network.
On Sinterklaas, Vjdeb and the PrinterPC I've got it to work as I think it should be for the local users that existed:
- Homedirs moved to nfs mount from Nurdservices
- Local homedirs and users deleted (except user 'printer' on PrinterPC)
- /home/ is mounted over nfs on boot
- LDAP users can log in and see their homedirs as if nothing has changed
- Users in the LDAP 'sudo' group can sudo on connected workstations.
- Homedir is created on NFS-export when adding a user to LDAP (like this)
Setting up other workstations in this way
To get this to work you need to:
- create all local users in LDAP (if they don't exist already)
- move homedirs to nurdservices (fix ownership if needed)
- delete local users (optional)
- delete local homedirs
- install libnss-ldapd and libpam-ldap
- config the binddn (read-user) in pam_ldap.conf and nslcd.conf (this is needed to look up the cn based on the UID the user inputs)
- mount /home from nurdservices over nfs
- configure the ldap in nss and pam (no ssl, so ldap://nurdservices/)
- restart nslcd and nscd
- if sudo doesn't work until you type 'id': lower the minimum_uid to 100 instead of the original 1000 in /etc/pam.d/common-* (why this works is kind of a mystery)

To do
- Read http://www.openldap.org/doc/admin24/slapdconf2.html
FTPdnevermindSambanevermindGet a certificate,Cert installed for ldap.nurdspace.nl. Allow access only over TLS as soon as this works- Setting "change password on first login" in FusionDirectory doesn't get enforced through PAM
- Migrate all local users on Infra machines to LDAP
- Migrate all homedirs to Nurdservices
- Migrate wiki users and merge them with other users
- Use LDAP as userdb back-end for wiki (like so)
- Add all relevant fields of Wiki users to LDAP profiles
- Maintain Members page from LDAP (Like so, but this has limitations. Maybe only members details pages?)
- Maintain sudo'ers only through the LDAP and disable local root accounts (backdoor in case of emergency?)
- Disable all relevant services on Nurdserver v1
