This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
The planner drafts a tree from names you type. The DN parser reads a distinguished name. Neither tool connects. A move is a later window.
One purpose per OU: users, computers, or a pilot. Do not design the tree around a single broken GPO. The domain is yours.
192.0.2.10/24 and example.com are documentation. They stay in the note.
The change you can finish
Apply nothing while you are writing the note. When the lab window opens, it is one change on the host named in the ticket. Read the draft, then the host, then decide.
Rollback is the file, the package version, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.
- Name the domain.
- Write the OU names.
- Leave moves out.
- Do not create the OUs during the reading.
- Stop.
Mistakes that outlive the command
Designing an OU Structure goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- Production objects moved during the reading.
- A domain you do not administer.
- A tree you cannot draw.
Decisions to write down
One decision for Designing an OU Structure: The names are written. Nothing was moved. Nothing was created. And the domain is yours.
Checks before you call it done
Confirm this before you call the change done: The domain is written. The OU names are written. Nothing was moved. Nothing was created. And the domain is yours. If one of those fails, stop.
# A plan, not a move.
# Do not move production during the reading.
# A domain you administer.Before you leave the host
Designing an OU Structure ends when the hostname in the prompt matches the hostname in the ticket. If it does not, you are on the wrong host. Stop. A command that succeeded on the wrong host is not progress.
The draft stays a draft until a person has read the names in it. A generator does not log into the host and does not know which disk is empty. You delete a line that names a host, a path, or an account you did not write down.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you leave on a host because a draft included them.
prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. The real secret stays in the password store.
One change is the window. If two things move and the result is wrong, you will not know which one did it. The next change waits for its own page.
If the same step fails twice, stop for the day. The failure is the result. Adding a forum command beside a half-applied change produces a host nobody can rebuild. Restore the copy you took first.
A second person reads the hostname and the change aloud. If they cannot find them in the ticket, the note is not done. Silence is not agreement. Then leave the host alone.
This page is a planning guide. It is not a vendor manual, not an official standard, and not permission to touch a host you do not administer. You do not disable a firewall, AppArmor, or SELinux to make a check pass.
