Concurrent logon problem...

Hi you all,

We are currently setting up a corporate wide file server using Samba
2.0.6 on a RedHat Linux Alpha platform. We only have Win98 clients, and
the Samba server is doing net logons (no password encryption) and master
browsing for the workgroup. The problem we have is that NMDB dies when a
logon occurs with a username which is already logged. After that, Win98
freezes when you try to log off (until you restart NMDB), and nobody can
log on any longer...

We haven't made any test on the Intel platform, and thus, we have no
idea whether it's a Samba problem or an Alpha problem. In the case it is
a normal behaviour, I think NMBD should not crash, even if it refuses
the login. I've tried the pre2.0.7 snapshot, and I get the same

Following is the corresponding trace in log.nmb, and our smb.conf file

Many thanks in advance, and congratulation for your great job...
