# Remove unused issuers
#
# When the IdP gets deployed, it generates a list of issuers that need to be removed and emails them
# to us. These emails are available in Zendesk - check the "Suspended Tickets" bucket for the most
# recent ticket titled:
# "[production] identity-idp error: ServiceProviderSeeder::ExtraServiceProviderError".
#
# This script iterates over a list of those issuers, outputs the data that is to be deleted, and
# then requires user confirmation before deleting the issuer and associated models.
#
#
# As of 11/2/2023: The rake task isn't working, to remove unused providers log into a box in the
# environment you want to remove unused providers from. Enter into a rails console and enter the
# following commands:
# > require 'cleanup/destroy_unused_providers'
# > issuers=['list','of','issuers','to','remove']
# > dup = DestroyUnusedProviders.new(issuers)
# > dup.run
