It worked, with one book :-(. Here is one with a different error code:
Code:
Fulfill /home/jens/Downloads/URLLink.acsm
Send request to http://acs4.onleihe.de/fulfillment/Fulfill
Exception code : 0x1003
Message : E_ADEPT_DISTRIBUTOR_AUTH http://acs4.onleihe.de/fulfillment/Fulfill urn:uuid:06707e6a-f172-4b12-9772-4a0601d656c2
What could that mean? (The same ACSM opens without complaints in ADE 2.0.)
