Caldav sync for iOS does not work for usernames containing spaces

[Nils160988]

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 #6192 (comment), but as it is just a comment there and the issue has already been closed, I thought to open a new one.

Maybe, any of the iOS-experts might have an idea @marinofaggiana ?

[marinofaggiana]

I think that the username is converted from iOS as Test%20Space

But @georgehrke is the expert.

[Nils160988]

Any news on this here?
Or can someone suggest a workaround? Changing the usernames is not possible as far as I know...

[Mululu]

we need a solution for this bug!

[Mululu]

Hi,

Is there any progress here?

Thank you!

[Mululu]

Any Solution?

Thanks!

[georgehrke]

No, a pull-request would very much be appreciated.

[Mululu]

I read in this post that a fix was introduced in the calendar. This will also fix this problem because unfortunately the "" is still replaced by a% 20.

This issue looks like the issue reported in #6192 (comment), but as it is just a comment there and the issue has already been closed, I thought to open a new one.

I closed my issue because I 'fixed' it by just leaving out the spaces.
However, the issue with names with spaces in them has not been fixed (yet).
