I'm a little confused...one machine for holding the authentication and
users home directories and another machine as the K12LTSP server...or one
machine for both?  If you go with a seperate server to hold the user
info....in other words the LDAP server....you can then have many K12LTSP
servers all pointing to this one authentication/home dir server.

do you need to have Windows workstations involved?  If not...don't bother
with smbldap....feel free to use FDS.  Samba/LDAP is what many of us have
to use to set up a common PDC/LDAP server for our mixed environments.  The
samba integration with FDS is not as mature as smbldap at this point which
is why many of us are using it.  Matt and I developed it
(smbldap-installer) out of a need to provide open source centralized
authentication for mixed networks.  In my case my Samba/LDAP server is my
PDC thus all my Windows servers and workstations suthenticate to it and it
houses the Windows roaming profiles...as well as my Linux servers...in
particular my K12LTSP servers point to it for authentication and NFS
mounted home directories (/home is exported from the Samba/LDAP server)

simply to accomodate Windows....Windows uses Samba and Linux uses the
openldap...yes they are integrated, but that's the seperation simply put. 
If Windows was not part of the equation then OpenLDAP would simply be
enough....for the most part.

Yes....piece of cake....and FDS should make this simple.

Let us know exactly what the layout is of what you're trying to do and we
can help....MANY of us are now running smbldap installations and have lots
of experience with centralized authentication as a result.  Also...Samba 4
may turn out to be the holy grail in some respects....keep us posted  :-)
