[dev] Current status of Kolab backend

[Mike Gabriel]

Hi all,

I have played with Horde 5 and a Kolab2 backend now for a while. My  
overall impression is that it works quite well.

But after three weeks of using it for my mail account (not for my  
customers, yet), I must also say that there are several issues that  
are not working.

1.
The Kolab authentication backend has been changed from IMAP to LDAP  
some time ago. In Horde3, LDAP was used as auth backend, and with LDAP  
as backend it is possible to list users and groups. This listing of  
users and groups is essential to the Horde internal ACL system  
(enabling certain Horde features for certain groups, etc.).

2.
Calendar sharing is broken. If I set my settings properly on the Kolab  
storage folders (using cyradm or my Horde3 instance that runs in  
parallel), then I can access other people's folders on the same Kolab  
server. However, if I start playing with the ACLs (on a Calendar  
share), then I loose all resource sharing ACLs on that share. :-(

3.
Is Kolab3 going to be supported? (/me will probably be the Debian  
maintainer of the new Kolab packages in Debian). So the question is,  
will it make sense to work on a Kolab3 integration with Horde inside  
of Debian (or not)?

4.
Is the Horde team open for Kolab relevant patches? Who has Git commit  
access in Horde to commit those patches?

5.
Gunnar Wrobel did most of the Kolab storage backend work in Horde.  
Someone on IRC mentioned, he is not working on Horde anymore. Are  
there other upstream Horde devs that maintain (and improve) the Kolab  
backend?

Regards,
Mike (aka sunweaver at debian.org)
