Organisations with multiple parents cannot be modelled

[thomasleese]

See the OrganisationFetcher on how to manually fix these:

signon/lib/organisations_fetcher.rb

Lines 65 to 76 in 37504d5

	def fix_parents_manually
	# Signon doesn't support multiple parents. Most of the time this is fine, but for
	# certain organisations this leads to a poor user experience and frequent support
	# tickets.
	MANUAL_PARENT_FIXES.each do |child_slug, parent_slug|
	child = Organisation.find_by(slug: child_slug)
	parent = Organisation.find_by(slug: parent_slug)
	next unless child && parent
	child.update!(parent: parent)
	end
	end

Given that this fix which was introduced in 31066d9 & #1570 is still in place, I assume this is still a valid issue.
