BOINC 5.4.9 client manager running at Ubuntu Linux 6.06 x86.

I have BAM account at boincstats. I noticed I can change username there. I did it. I failed to synchronise BOINC client with BAM account after that change. I changed username from "knekos" to"PSL".

I understand that it is risky idea to change username but as it is enabled why not try it. User accound has some CPID that is not changed, email address is the same as well. Username should not not be the primary key.

Is it a BOINC client bug? Or design limit? It seems that I cannot even get new work units after username change in BAM. I noticed this on SIMAP project. My SIMAP account was changed correctly, new username is there.


When I do "SYNCHRONIZE with BAM" in my boinc client I receive error "Failed to update account, user not found!"

I can see that GIF with statistics still have the original user name ( http://www.boincstats.com/signature/user_675138.gif).

User graph pagelists original username too (http://boincstats.com/stats/boinc_user_graph.php?pr=bo&id=41c0f4c5c26f84008e5a364cb553eec9)

I see the same problem on Windows client running 5.4.11 so this issue is not Linux specific..

In message window I can see message "Account manager error: 0 User not found!" after client start. The same error is added there when I force manual synchronisation.

These two points were fixed, username have changed. But Boinc clients still cannot synchronize with BAM account. Is it design limit/bug?

The username in the stats and BAM! have no direct relationship. Username in BAM! comes from the user directly, username in stats comes from the XML files, thus may lag.

BOINC client is designed to use username/password combo to connect to AMS systems. So if you change the username, you have to change the client info for connecting to BAM.

I see it now, file acct_mgr_login.xml has username there:
<acct_mgr_login>
<login>knekos</login>
<password_hash>
...
</acct_mgr_login>

Well this is simple but not smart. Why not use some unique ID, like CPID. Password could be problem as well. DO I understand correctly that when I will change acount password at bam.boincstats.com, I have to change password on all clients? If ythis is true, it is not good design.

I found that I can detach client from BAM and attach to BAM again with new username. It is workarround to" User not found" error.

It's designed this way by the BOINC devs. I agree that it should be different.
