This should be Contributor. I will create a separate bug to address this.

@xenolinux We can address this as part of separate PR, may be through a Bug, as this is not part of this work.

I would like to replace the command on lines 174-175 with the command in the [NOTE], like this:

[source,terminal]
----
$ az ad sp create-for-rbac --role <role_name> \// <1>
     --name <service_principal> \// <2>
     --scopes /subscriptions/<subscription_id> <3>
----
<1> Defines the role name. You can use the `Contributor` role or you can specify a custom role which contains the necessary permissions.
<2> Defines the service principal name.
<3> Specifies the subscription ID.

Then on line 199, you can say "If you applied the Contributor role to your service principal, assign the User Administrator Access role by running the following command." This lets you remove the [NOTE] entirely.

The problem with having the [NOTE] after the procedure is that the customer might work through the procedure, then find the note and realize that they have to undo and redo some work.

I think we should also add a prerequisite on line 25 saying "If you want to use a custom role, you have created a custom role with the required permissions listed in the section titled 'Required Azure permissions'" or something similar, so that customers prepare this role before going through the procedure. What do you think?

+1 for adding a prerequisite. I addressed it as https://github.com/openshift/openshift-docs/pull/56274/files#diff-ffc3e09f08e289cfe3c74a47f411658813e9b68f96708e1a8feaeca5636e0c5aR37-R42.
I used ifdefs to include the exact name of the section. I thought it would be easier for a user. Please let me know if you have any suggestions on this.
