Domain logins with ip aliasing under Linux

[tonnesen at cmsd.bc.ca]

I'm having trouble with domain logins under Linux.  I have an ip alias on
my ethernet card on the samba server so that I have a real ip subnet, and
a fake, masqueraded subnet.

eth0	209.xxx.xxx.1 netmask 255.255.255.192
eth0:0	192.168.1.1 netmask 255.255.255.0

If the client machine has a "real" ip address (209.xxx.xxx.2) everything
works fine, if it has a "fake" ip address (192.168.1.2) I get the
following in the nmb log:

   process_logon_packet: Logon from 192.168.1.2: code = 0

And the logon on the client fails with a "Bad password or access to server
denied" message.

I've tried adding:

   interfaces 192.168.1.1/24 209.xxx.xxx.1/26

to the smb.conf file, but I get the same result.

Is this a known problem, or do I have something set up wrong here?  I
could always chuck out the real ip addressses and just use the fake subnet
if I must, but I'm bound to run into a situation where a workstation needs
a real ip address at some point. 

Software Version Info:
   samba 1.9.18p8
   debian 2.0 (kernel 2.0.32)
