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]] it's working for the local users that existed:
+== Wiki ==
-* Homedirs moved to NFS mount from [[Proxmox1]]
+Authentication on this wiki is done via SAML using a combination of SimpleSAML and Keycloak. Keycloak uses LDAP as an identity source.
-* 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 ([http://documentation.fusiondirectory.org/en/documentation_faq/command_after like this])
-* Port 636 (ldaps) is [[Cisco800series#Port_forwarding_howto|forwarded]] to [[NURDServices]] for future use by the [[Wiki]]
-= Setting up other workstations in this way =
+== Gitlab ==
-To get this to work you need to:
+See [[Network/Roadmap/MigrateToGitlab|our Gitlab instance]]
-* create all local users in LDAP (if they don't exist already)
-* delete local users (optional)
-* move homedirs to nurdservices (fix ownership because LDAP-users have a different UID)
-* delete local homedirs
-* mount /home from proxmox1:/mnt/md0/homedirs over nfs (put it in /etc/fstab)
-* install [http://wiki.debian.org/LDAP/NSS#NSS_Setup_with_libnss-ldapd libnss-ldapd] and libpam-ldap (URI ldaps://ldap.nurdspace.nl/)
-* put https://www.sslcertificaten.nl/files/PositiveSSLCA2.crt in /etc/ssl/certs/ with permissions 644
-* in nslcd.conf set the following:
- uri ldaps://ldap.nurdspace.nl/
- base dc=nurdspace,dc=lan
- binddn cn=read-user,ou=systems,dc=nurdspace,dc=lan
- bindpw (obtain from other machine)
- ssl on
- tls_reqcert demand
- tls_cacertfile /etc/ssl/certs/PositiveSSLCA2.crt
-* restart nslcd
-* this information should also be used for pam_ldap.conf
-* sudo might not work until you type 'id' which is [http://wiki.debian.org/LDAP/PAM kind of a mystery]
-Also useful: http://www.debian-administration.org/article/OpenLDAP_installation_on_Debian#NSS_configuration
+== Wifi (Spacenet) ==
+TODO: Is broken as of now
-In certain cases sudo can break. This can be fixed with [http://osdir.com/ml/general/2013-01/msg44182.html a patch] while it's not fixed properly.

-* Merge all unwanted users to use 'history'
-* Inform wiki users that will be renamed
-* Migrate/merge [[wiki]] users to LDAP
-* Create necessary wiki groups (bureaucrats, admins, other?)
-* 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])
-* 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 only displays 1 entry.
