If the number of WS/users is little you can use the WINS param in the
Network|TCP/IP config pane, to redirect the PDC search, but if the
number of WS is big and you need several PDCs. 
The last year, we have synchronized the smbpasswd (and /etc/passwd)
files via NFS or similar, but this year we are testing samba with LDAP
(CVS source HEAD branch).
Another solution is samba with NIS+.

configure:
  --with-ldap     Include LDAP support
  --with-nisplus     Include NISPLUS password database support

...but you need the /etc/passwd accounts in one PDC and almost the
/etc/group well synchronized...
