I’m experiencing something similar, stable Debian, all updates.
Here are the relevant sections from my mt-daap.conf and the mt-daap log (at level 9):
(conf):
# admin_pw (required)
#
# This is the password to the administrative pages
admin_pw = coachz
(log):
2008-07-08 12:53:35 (b54bbbb0): Decoded admin:coachz
2008-07-08 12:53:35 (b54bbbb0): Decoded user=admin, pw=coachz
2008-07-08 12:53:35 (b54bbbb0): Added *WWW-Authenticate=Basic realm=”webserver”*
2008-07-08 12:53:35 (b54bbbb0): Thread 7: Entering ws_returnerror (401: Unauthorized)
Does anyone know what deb package this is related too? Maybe something I should try from “unstable”?
