[Samba] Samba PDC/LDAP not mapping "logon drive"

[Jeff Wiegley]

Well it took forever (three days actually) to:
  1) setup a working ldap server.
          Unix users now authenticate against the LDAP server perfectly.
  2) Setup samba to use LDAP authentication.
  3) Get the WindowsXP machines to become members of the domain.

Everything seems to be working fine except for
  1) roaming profiles, and
  2) User's home directory (logon drive) doesn't get mapped during
       log in.

So basically I can log in to the workstation. My user can even
see their home directory shares (via the [homes] share) but
it doesn't get mapped automatically as drive E: (or any other
drive letter) when they log on.

I can sort of live without roaming profiles but the failure to
map the logon drive automagically isn't acceptable.

Could somebody please help me??

I have the logon stuff setup as:
logon path = \\%L\profiles\%U
logon drive = E:
logon home = \\%L\%U

Which I think should map \\SERVER\USERNAME as drive E:
autmatically whenever they log in (substituting the proper
values for SERVER and USERNAME of course.)

It doesn't work. The profile doesn't seem to roam either as
I expect it would with logon path. The path exists and I have
enabled the thingy in gpedit.msc which is required for WinXP
machines. But this is really secondary. I need the logon drive
fixed roaming profiles would just be a nice bonus.

here's my full smb.conf, sorry to be so verbose but I wanted to
include it all because I don't understand much of the LDAP, PDC
or roaming profile entrystuff in this so I didn't want to miss
something:
