Zimbra URL /dav/ is missing -> can not synchronize

[Voidl B]

I think this is a DAVx5 issue.
After adding a new Zimbra account the device cannot synchronize:

First try: Sign in with URL and username

• Base URL: https://zimbra.host.tdl
  -> Result: DAVx5 recognized a calendar but with url https://zimbra.host.tld/myUser/Calendar
  -> Because that calendar doesn’t exist: Error

Second try:

• Base URL: https://zimbra.host.tld/dav
  -> Result: Same as without /dav

Third try:

• Base URL: https://zimbra.host.tld/dav/
  -> Result: DAVx5 cannot find anything at all.

First/second try threw an exception:
