Scalix Forums

I am writing an API client for Scalix, working from the API Guide,
and I am having a problem that I don't understand with Authentication.
The client starts by sending the message:

GET /api/userinfo HTTP/1.1\r\n
Host: pca.local:8080\r\n
Authorization: Basic cGV0ZXIgc2hhcnA6bGludXgK\r\n

where the authentication string is the Base64 version of

peter sharp:linux

This request is rejected by Scalix as an authentication failure.
I am using Wireshark to monitor network traffic, and between my initial
request message and the rejection response, I can see a pair of messages,
presumably from the Scalix 'logon server' to the IMAP server as follows:
First message:

A1 AUTHENTICATE PLAIN

Second message:
cGV0ZXIgc2hhcnAAcGV0ZXIgc2hhcnAAbGludXgK\r\n

but this decodes as

So what's going on here ? It looks to me as if Scalix has decoded my
string, garbled it, and re-encoded it before passing it to IMAP, which
not surprisingly rejects it.

I'm running Scalix CE 11.4.2, on OpenSUSE 11.0, BTW.
