As per #3047.
Also made some SAML specific fixes:
- IDP initiated login was broken due to forced default session value.
Double checked against OneLogin lib docs that this reverted logic was fine.
- Changed how the saml login flow works to use 'withoutMiddleware' on
the route instead of hacking out the session driver. This was due to
the array driver (previously used for the hack) no longer being
considered non-persistent.
- Migrated env usages to config.
- Removed potentially unneeded config options or auto-set signed options
based upon provision of certificate.
- Aligned SP certificate env option naming with similar IDP option.
Tested via AFDS on windows server 2019. To test on other providers.
Session was being lost due to the callback POST request cookies
not being provided due to samesite=lax. This instead adds an additional
hop in the flow to route the request via a GET request so the session is
retained. SAML POST data is stored encrypted in cache via a unique ID
then pulled out straight afterwards, and restored into POST for the SAML
toolkit to validate.
Updated testing to cover.
- Included tests to cover for LDAP and SAML
- Updated wording for external auth id option.
- Updated 'assertPermissionError' test case to be usable in BrowserKitTests
- Aligned and formatted config options.
- Provided way to override onelogin lib options if required.
- Added endpoints in core bookstack routes.
- Provided way to debug details provided by idp and formatted by
bookstack.
- Started on test work
- Handled case of email address already in use.
