LDAP

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

• Sinterklaas
• Vjdeb
• PrinterPC
• Nurdservices

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

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
• 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/)
• and add a line to /etc/pam.d/common-account:

session required pam_mkhomedir.so skel=/etc/skel/ umask=0022

This step will no longer be needed once homedirs are created when you add a user to the LDAP.

To do

• FTPd
• Samba?
• Get a certificate, allow access only over TLS
• Create homedir on NFS-export when adding a user to LDAP (maybe like this?)
• 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 through the LDAP and disable local root accounts like so (backdoor in case of emergency?)
• Disable all relevant services on Nurdserver v1
