I don't know if technical list is the most appropriate one... perhaps may be useful.

Several advices:
Read in the "samba-howto" or "samba by example", etc. about the memory 
requirements (you may runs also very short of disk space).

Also consider that:
- you not provide data about number of users
- the LDAP runs in the same machine, and the slapd.conf don't show any 
reference about cache size directives... the ldap is very sensible about 
caches, memory and so...
- the PDB/BDC sync section says the use of rsync for synchronization for 
  netlogon... for the *.bat I suppose  (the profiles are roaming?)
- perhaps you should replace the /etc/passwd with pam_dap (ldap 
posixAccount) also.
- please, follow the samba-howto collection steps.
- your configuration files have a lot of comments, pretty unreadable, 
please, use/post clear ones.
