I understand the upsides of OAuth and initially we attempted to use OAuth in more apps, however more users prefered using ldap for tighter integration, as ldap usually gives a better user experience inside the app not leaving the app first for the redirect. Also the auto login mechanism in OAuth was sometimes confusing. We won't put up the effort at the moment to support multiple auth backends directly in the app installation/configuration out of the box as that increases the testing amount to ensure proper updates.
@girish I have a 238 ko iCal file.
I've split it in twice and I went from 250 importation err from 1 err.
The problem should come from that, thanks!
I was at the beginning thinking about it (splitting the file) but after that, I was focusing on RateLimit - wrong way! Also, I advise people which want to import a big file to increase drastically the mem allowance of the app (2Gb in my case)
For the CSP settings, this indeed cannot properly be done on a platform level, as apps require differently strict settings there and have to provide this on their own, so this should ideally be fixed in each app upstream.
