Samba in an HA environment

By the way... there´s an uggly, little bug in nmbd_nameregister.c
So it could be a very bad idea to use "bind interfaces = true" and "interfaces =..."

For example this bug will happen, if you´re using samba as dmb and if samba
has to register his ip(s) on another wins-server.
---
interfaces = aaa.bbb.ccc.ddd/netmask 127.0.0.1
bind interfaces = true
domain master = true
wins server = eee.fff.ggg.hhh
---
(The localhost is necessary to allow password changes on the samba server)

>From now on, the complete browsing in the domain sucks down... 
( 1st: Samba will be rejected to add his ips on the wins server, because nmbd
       is trying to register localhost!!!!!
  2nd: Samba will not become a dmb
  3rd: all LMBs could not sync their list with the dmb
  and so on...
)

If someone is interested in more (and closer detailed) informations, just feel free to
connect me via mail. I could offer some logfiles and for some hacker it
would be possible to get an account on a testmachine in our network.

(sorry for the bad english - maybe it´s funny... ;) )

Liebe Gruesse, yours
