+I recently broke this by deleting the database and restarting it.
+
+This was actually an accident.
+
+Anyway, I had a backup but went ahead and rolled forward to test the
+terraform-a-new-keycloak idea... and it worked, I think!
+
+So I had a blank keycloak sitting in kubernetes based on the manifests here.
+
+I then moved the tfstate away and reterraformed the oidc clients and ldap
+configs back into existence.
+
+HOWEVER: the oidc secrets will be different.  To unscrew this up, the secrets
+must be restored.  This is most easily done by restoring the random password
+from the previous state.
+
+First, we'll delete the existing new secrets.  Then we'll restore the others.
+
+```bash
+jq -c '.resources[]' terraform.tfstate.1681525339.backup | \
+  jq -r '
+    select(.type == "random_password")
+    | @sh "terraform state rm \(.module).\(.type).\(.name)\"[0]\""
+  ' | sh -s
+```
+
+I screwed my system up on Friday, April 14 at 21:22:19 CDT in the year 2023.
+
+Now we'll restore the good secrets.
+
+```bash
+jq -c '.resources[]' terraform.tfstate.1681525339.backup | \
+  jq -r '
+    select(.type == "random_password")
+    | @sh "terraform import \(.module).\(.type).\(.name)\"[0]\" \(.instances[0].attributes.result)"
+  ' | sh -s
+```
+
+At least, I think this worked... I also had to set the epoch to 1 for all of
+these (by modifying the state file by hand).
