What is Bookstack

From https://en.wikipedia.org/wiki/BookStack

:::note BookStack is a free and open-source wiki software aimed for a simple, self-hosted, and easy-to-use platform. Based on Laravel, a PHP framework, BookStack is released under the MIT License. It uses the ideas of books to organise pages and store information. BookStack is multilingual and available in over thirty languages. For the simplicity, BookStack is considered as suitable for smaller businesses or freelancers. :::

SAML2_DISPLAY_NAME_ATTRIBUTES=Name

Notes

:::note BookStack will attempt to match the SAML user to an existing BookStack user based on a stored external id attribute otherwise, if not found, BookStack will effectively auto-register that user to provide a seamless access experience. :::

:::note SAML Group Sync is supported by Bookstack. Review the BookStack documention on the required Environment variables. https://www.bookstackapp.com/docs/admin/saml2-auth/ :::
