[horde] shared calendars caldav thunderbird

[Álvaro Javier Gasco Fernández]

Hi all.

I have a question about shared calendars in thunderbird with caldav. One
user called "Hostmaster" has shared a calendar with other one, called
"Abuse". This user wants to subscribe both calendars (Abuse and
hostmaster's shared) in Thunderbird. With his own calendar there's no
problem, but when he wants to add the shared calendar (with all
permissions) he receives this in logs...

CalDAV: No resource type received, hostmaster doesn't seem to point to a
DAV resource (in thunderbird)
CalDAV: Unexpected status 403 while querying options hostmaster

The user and password when thunderbird prompts is Abuse for both calendars.
Abuse calendar: https://**************/rpc.php/calendars/abuse@
*********/calendar:Gn2LOxnayclzYv4pX418Rw1/

Hostmaster's Shared Calendar wiht abuse: https://
************/rpc.php/calendars/hostmaster@
************/calendar:Oy9Ycj5gmwJy656_adne8Q2/

I really appreciate your help.

Best regards.
