Description

Steps to reproduce
  1. Create a user containing a space character like "Test Space"
  2. Try to add caldav account on iOS
Expected behaviour

Account is created and caldav syncs happily

Actual behaviour

Nothing ("sync via SSL is not possible" which is not correct)

For a user called "TestSpace" everything works as expected.

This issue looks like the issue reported in https://github.com/nextcloud/server/issues/6192#issuecomment-447655559, but as it is just a comment there and the issue has already been closed, I thought to open a new one.

Research direction

Start at the CalDAV account setup and sync path, comparing a username containing a space with the working “TestSpace” case on the reported Nextcloud 15 and iOS setup. Inspect the request and server response during account creation; done means iOS can create the account and synchronize successfully for usernames with spaces.
