Login issue

Hi,

i did 2 succesfull installs from airtime. The one on the test environment works fine. In my production environment i can see errors:
in /etc/service/pypo-liquidsoap/log/main/current:
@400000004d6388cb00a9c2fc 2011/02/22 10:58:25 [airtime(dot)mp3:3] Connecting mount airtime.mp3 for source@127.0.0.1...
@400000004d6388cb021b7f54 2011/02/22 10:58:25 [airtime(dot)mp3:2] Connection failed: 401, Authentication Required (HTTP/1.0)!
@400000004d6388cb021cb004 2011/02/22 10:58:25 [airtime(dot)mp3:3] Connection failed, will try again in 5 sec.

and in /var/log/icecast2/error.log:
[2011-02-22 11:02:43] INFO connection/_handle_source_request Source logging in at mountpoint "/airtime.mp3"
[2011-02-22 11:02:43] INFO connection/_handle_source_request Source (/airtime.mp3) attempted to login with invalid or missing password

also, i cannot see the mountpint on the icecast status page. I did change the default passwords in the icecast.xml
Is there a place in a config file somewhere i should change?
I hope you can help me. I love the airtime product and intend on using it a lot.

Thanks ever so much for your time and effort in advance.

Kind regards,
Ed Boon
