Description

Hey there,
when trying to import an .ics Appointment file via Caldav (for example in Thunderbird, where the Calender is added via Caldav), specific UIDs (for example: "UID:flexperto/mlpfinanzberatung/prod" doesn't work, but "UID:flexperto/mlpfinanzberatung" works fine)  specified in the .ics file will result in an 404 error, screenshot attached.

The error message of thunderbird is: (German)
"Status-Code: 2147500037, Die Anfrage kann nicht verarbeitet werden.

Server Replied with 404"

I get the same error (404) when importing the .ics file with my smartphone. There i can import the .ics in my aCalendar app, but when the OpenSync App tries to synchronize the calendars via Caldav, it gives the error message 404 for this specific appointment.

importing the .ics with the SoGo Webinterface works just fine

Since the 404 appears in the SOGo log, it seems like this is a SOGo issue. If it was due to our HTTP proxy rules, it would appear in the Nginx log only.

RFC 5545 says that the UID must be globally unique. The one in your sample probably isn't -- it doesn't contain any timestamp or randomness. But nonetheless, there does not appear to be prohibition against having multiple slashes in the UID. I haven't been able to find the place in the SOGo source code that handles CalDAV URLs, but you could still try filing a bug with SOGo.
