When I attach my BOINC Manager to BAM I get the message that I am now connected to a AMS but in the log of BOINC manager appears the message "no accounts reported by account manager" and the computer doesn't show up in the computer list of the BAM menu.
Additionally in the XML Reply file (acct_mgr_reply...) it shows : "No user..."

What is missing?

Perhaps you have entered wrong email or password

I have enterd the BAm user name and the password AND I get the answer that I am now connected to the AMS. But then the log message appears and the computer is not listed in the BAMS menu (Rechnerliste)!

Shame on me. I had an old version of Boinc manager (5.2.13) running. This version was always rejected without a notice for the user. Upgrading to 5.4.9 (macintosh universal binary) solved the problem.
