# Tracking document for new PVV kerberos auth stack
Bensinstasjon på heimdal
### TODO:
- [ ] setup heimdal
- [x] ensure running with systemd
- [x] compile smbk5pwd (part of openldap)
- [ ] set `modify -a -disallow-all-tix,requires-pre-auth default` declaratively
- [ ] fully initialize PVV.NTNU.NO
- [x] `kadmin -l init PVV.NTNU.NO`
- [x] add oysteikt/admin@PVV.NTNU.NO principal
- [x] add oysteikt@PVV.NTNU.NO principal
- [ ] add krbtgt@PVV.NTNU.NO principal?
- why is this needed, and where is it documented?
- `kadmin check` seems to work under sudo?
- Fix FQDN: https://github.com/NixOS/nixpkgs/issues/94011
https://github.com/NixOS/nixpkgs/issues/261269
- [ ] setup cyrus sasl
- [x] ensure running with systemd
- [x] verify GSSAPI support plugin is installed
- `nix-shell -p cyrus_sasl --command pluginviewer`
- [x] create "host/localhost@PVV.NTNU.NO" and export to keytab
- [x] verify cyrus sasl is able to talk to heimdal
- `sudo testsaslauthd -u oysteikt -p `
- [ ] provide ldap principal to cyrus sasl through keytab
- [ ] setup openldap
- [x] ensure running with systemd
- [ ] verify openldap is able to talk to cyrus sasl
- [ ] create user for oysteikt in openldap
- [ ] authenticate openldap login through sasl
- does this require creating an ldap user?
- [ ] fix smbk5pwd integration
- [x] add smbk5pwd schemas to openldap
- [x] create openldap db for smbk5pwd with overlays
- [ ] test to ensure that user sync is working
- [ ] test as user source (replace passwd)
- [ ] test as PAM auth source
- [ ] test as auth source for 3rd party appliation

- Doesn't seem like there are many good ones out there. Maybe phpLDAPAdmin?
- [ ] Set up kerberos SRV DNS entry
