[Samba] LDAP and Multiple Samba Hosts Issue

[Derek J. Balling]

OK, I'm trying to get Samba working with LDAP. And I have it... sort of.

I have a Samba server TESTBOX, and I can authenticate to it just fine.

It seems taht if I change the "netbios name" (which I was doing to 
simulate "connecting from some other samba server in our network"), I 
get:

$ smbclient //FS01/files 'foo' -U dballing -I 
testbox.byramhealthcare.com -N -d 4
added interface ip=10.15.49.49 bcast=10.15.49.255 nmask=255.255.255.0
Client started (version 3.0.0beta1-1 for Debian).
Connecting to 10.15.49.46 at port 445
  session request ok
Serverzone is 14400
Doing spnego session setup (blob length=58)
got OID=1 3 6 1 4 1 311 2 2 10
got principal=NONE
session setup failed: NT_STATUS_INTERNAL_DB_ERROR

... if I set the "netbios name" back to "TESTBOX", it works just fine:

$ smbclient //TESTBOX/files 'foo' -U dballing -I 
testbox.byramhealthcare.com -N -d 4
added interface ip=10.15.49.49 bcast=10.15.49.255 nmask=255.255.255.0
Client started (version 3.0.0beta1-1 for Debian).
Connecting to 10.15.49.46 at port 445
  session request ok
Serverzone is 14400
Doing spnego session setup (blob length=58)
got OID=1 3 6 1 4 1 311 2 2 10

  tconx ok

... is the NETBIOS name stored in the LDAP password info in such a way 
that it would be impossible to connect from two different netbios 
hosts? This seems like it would be counterproductive as a "centralized 
authentication database" for more than one server. Am I doing something 
wrong?
