+### 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
+    - [x] add krbtgt/PVV.NTNU.NO@PVV.NTNU.NO principal?
+      - why is this needed, and where is it documented?
+      - `kadmin check` seems to work under sudo?
+      - (it is included by default, just included as error message
+         in a weird state)
+
+    - [x] Ensure client is working correctly
+      - [x] Ensure kinit works on darbu
+      - [x] Ensure kpasswd works on darbu
+      - [x] Ensure kadmin get <user> (and other restricted commands) works on darbu
+
+    - [ ] Ensure kdc is working correctly
+      - [x] Ensure kinit works on dagali
+      - [x] Ensure kpasswd works on dagali
+      - [ ] Ensure kadmin get <user> (and other restricte commands) works on dagali
+
+    - [x] Fix FQDN
+      - https://github.com/NixOS/nixpkgs/issues/94011
+      - https://github.com/NixOS/nixpkgs/issues/261269
+      - Possibly fixed by disabling systemd-resolved
+
+- [ ] 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 <password>`
+  - [ ] 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
+
+- [ ] Set up ldap administration panel
+  - Doesn't seem like there are many good ones out there. Maybe phpLDAPAdmin?
+
+- [ ] Set up kerberos SRV DNS entry
