Apple is also developing a CalDAV server: <a href="http://trac.macosforge.org/projects/calendarserver/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://trac.macosforge.org/projects/calendarserver/ </a> It's written in Python, and is FOSS I'm not sure of the exact license though. I know from the mailing list that it will compile on Linux, but installation and configuration aren't that user friendly at the moment. Another idea anyway. <div>On 10/11/07, Jack Ryder <<a href="mailto:ryder.jack@gmail.com">ryder.jack@gmail.com</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> I agree calendar sharing is a missing features under GNU/Linux. However I recently tested two interesting email server platform for Linux. - Zimbra Open Source Edition. - Hula (the open source edition of the former Novell NetMail). Both are fully supported under Ubuntu (6.06 at least) Zimbra provides more features and it is a wonderful products but is not release under GPL. Hula is still beta but was based on the rock solid Netmail platform. It has been released under GPL. I would love that the community invests more efforts into Hula (seems that Novell totally stops supporting the project) and makes it come to universe. I think it is a good basis. Novell formerly planned to merge Hula with iFolder (GPL as well) to provide a collaborative solution for the community but I don't read any recent news about this. <div>2007/10/11, Dave Kempe <<a href="mailto:dave@solutionsfirst.com.au" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)"> dave@solutionsfirst.com.au</a>>: <div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi Guys, before I make a wiki page about calendar sharing, I was wondering if anyone has any other recent experiences with Calendar sharing with ubuntu? from the server side of course. I have one I would like to share and think that it represents something we will be offering as a calendar sharing solution as an alternative to exchange for our SME clients. I have a client who already uses Thunderbird and courier imap. They lacked internal facing calendar sharing and I hadn't checked the state of play recently. So I installed lightning (the thunderbird add-in for calendaring) and setup Really Simple CalDAV Store: <a href="http://rscds.sourceforge.net/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://rscds.sourceforge.net/</a> It was pretty easy (they provide an apt source) to get going and seeing as I already had postgres for their CRM (centric) worked out pretty well. So with a little amount of effort (just configuration) I was able to have calendars all shared and updated in a read write fashion from Thunderbird. Access control is handled by the RSCDS web interface and works pretty well, though the group specification needs some work... A few points about the solution: * Lightning is under heavy development now and will be even nicer by Hardy release time * RSCDS needs more authentication options. I am happy to contribute coder time to make PAM-auth happen, as this would let us tie into other authentication schemes. The current auth means you have yet another silo of user/passes. * RSCDS is begging to be integrated in to Ebox or some other web interface for easy access (not that I use or have tried ebox) * I think the biggest roadblock to the whole linux-groupware-problem is actually Outlook, so I wanted a solution whereby people did not have to use it. Thunderbird/IMAP/RSCDS/Webmail(squirrelmail) will get most people so far its now a great combo. I have tried other shared calendaring solutions on Linux servers with windows clients. None worked anywhere near as well as this combination, and the most sophisticated (Zimbra, Scalix, etc) a really Outlook servers... not interested :) You see the big picture here is that people need to stop using Windows on the desktop... and freeing them of Outlook is an important first step, as a whole swathe of users are tied to it. The only reason to use squirrelmail at present is the large number of plugins - change password, Seive rules and/or vacation are important user facing admin functions. Aside from that, squirrelmail kinda blows for large mailboxes. Its getting better and I prefer v-webmail for my inbox and folders (just don't get the plugins) Shared calendaring is here people! lets do it :) Let me know what you think...
