Filters - Not working

[Christian Tardif]

Hi,

I have a strange problem in my Kolab 3 implementation regarding Sieve 
scripts.

If a user goes into Settings, then clicks on Filters, he gets an error 
saying that:

* Unable to connect to server

In  the web logs, I see these two errors, one after the other:

[Thu Oct 03 22:31:43 2013] [error] [client 76.64.252.185] No supported 
authentication method found. The server supports these methods: , but we 
only support: DIGEST-MD5, CRAM-MD5, EXTERNAL, PLAIN, LOGIN (): ,

What is that all about?
