Fedora :: F13 X86_64 Evolution With Exchange-mapi Gives MapiLogonProvider:MAPI_E_LOGON_FAILED?

I have F13 x86_64 with all updates. I tried to setup Evolution to access our corporate MS Exchange 2007 server, so I installed evolution-mapi-0.30.3-1.fc13.x86_64 , yum pulled in also dependecies samba4-libs-4.0.0-22.alpha11.fc13.x86_64 and openchange-0.9-2.fc13.x86_64.

Installation went OK, then I tried to setup the account in Evolution. I chose :
server type: Exchange MAPI
server: mailserver.corporatedomain.com
username: my.username
Domain name: corporatedomain.com

Of course, the names of server, domain and my username are different in reality, however, I entered them in the same format as written here. The communication with mailserver is on corporate internal LAN - no routers or firewalls between. When I click "Autheticate" it prompts me for password, I put in the correct password but I get the error: Authentication failed. MapiLogonProvider:MAPI_E_LOGON_FAILED

I tried to put in the IP address of the mailserver instead of its network name, tried to put in the IP of the domain controller, enter the domain name in uppercase, all sorts of combinations but nothing works.

is there a way to get authenitcated??? I googled far and wide, but did not find the cause for Here is the output from evolution when started in gnome-terminal:
