LDAP Property "Tool Image" (as page type) with input value "File:{{{Picture}}}" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process. {{{Picture}}} {{#if:Yes | [[Tool Owner::{{{ProjectParticipants}}} | }} {{#if:Yes | [[Tool Cost::{{{Cost}}} | }}

Status

We are currently running on FreeIPA.

Connected machines and services

Virtual Machines

You can use the following systems by logging into them using your LDAP account. These systems are only available when you are connected to the space network, or you have a working VPN tunnel to the space. Note that you need to be part of the BOFH group to gain root access. If you need root, ask someone from the BOFH team to see whats possible.

services-1.lan.nurd.space
services-2.lan.nurd.space
gitlab.vm.nurd.space
minio.vm.nurd.space
navi.vm.nurd.space
gh-runner-almalinux.vm.nurd.space
gh-runner-debian.vm.nurd.space

All machines are deployed using a combination of OpenTOFU, cloud-init and Ansible via an CI/CD pipeline running on Gitlab. Configuration is done via GIT. If you need a machine for any purpose, ask the BOFH team.

TODO: Make this available for members without BOFH being involved.

Wiki

Authentication on this wiki is done via SAML using a combination of SimpleSAML and Keycloak. Keycloak uses LDAP as an identity source.

Gitlab

See our Gitlab instance

Wifi (Spacenet)

TODO: Is broken as of now

DHCP

See the network page.

(Un)locking the front door

See the Door lock page.

-On [[Hp_dc5800_sinterklaas|Sinterklaas]], [[Dell_Optiplex_GX270|Vjdeb]] and the [[PrinterPC]] I've got it to work as I think it should be for the local users that existed:
+TODO: Make this available for members without BOFH being involved.
-* Homedirs moved to nfs mount from [[NURDserver_v2|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.

+== Wiki ==
-To get this to work you need to:
+Authentication on this wiki is done via SAML using a combination of SimpleSAML and Keycloak. Keycloak uses LDAP as an identity source.
-* 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 [http://wiki.debian.org/LDAP/NSS#NSS_Setup_with_libnss-ldapd 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:
-<code>
+== Gitlab ==
-session    required   pam_mkhomedir.so skel=/etc/skel/ umask=0022
+See [[Network/Roadmap/MigrateToGitlab|our Gitlab instance]]
-</code>
-This step will no longer be needed once homedirs are created when you add a user to the LDAP.
+== Wifi (Spacenet) ==
-* 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 a mystery)

-= To do=
+== (Un)locking the front door ==
-* FTPd
+See the [[Network/Services/DoorLock|Door lock page]].
-* Samba?
-* Get a certificate, allow access only over TLS
-* Create homedir on NFS-export when adding a user to LDAP (maybe [http://documentation.fusiondirectory.org/en/documentation_faq/command_after 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 [[NURDserver_v2|Nurdservices]]
-* Migrate [[wiki]] users and merge them with other users
-* Use LDAP as userdb back-end for [[wiki]] ([http://ryandlane.com/wprdl/2009/03/23/using-the-ldap-authentication-plugin-for-mediawiki-the-basics-part-1/ like so])
-* Add all relevant fields of Wiki users to LDAP profiles
-* Maintain [http://nurdspace.nl/Category:Members Members] page from LDAP ([http://www.mediawiki.org/wiki/Extension:External_Data#.23get_ldap_data_-_retrieve_data_from_LDAP_directory 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
