Add Minio Caveat

[MegaShinySnivy]

What is the vendor's name?
Minio

What is the vendor's pricing site?
https://min.io/pricing

What is the base pricing? Use the lowest tier that looks sane for a small business customer, not free or personal tiers.
Free for selfhosted

What is the minimum pricing for SSO support?
N/A

Does this pricing info come from a quote or other non-public source?
No

Are there any caveats we should list in the footnotes?
Minio purposefully kneecaps their SSO support by making it so if the server does not detect the provider at startup, it will not expose that provider for logon unless you restart the service, leading to downtime. A PR was provided to fix this, but was only permitted for use in their enterprise offering.
