After updating Samba from 3.0.20 to 3.0.21c NMDB is only bound to my NIC's IP but no longer to 127.0.0.1 though my smb.conf parameters are interfaces = 127.0.0.1, 192.168.x.x/255.255.255.0 bind interfaces only = yes As a result SWAT does not show the status of NMDB any longer. Any idea which parameters are different to 3.0.20 or is this a bug in 3.0.21c?
