Installations that use tdbsam have user and group accounts in two places:

UNIX Accounts:
	/etc/passwd + /etc/shadow: Holds the POSIX (system) user accounts
	/etc/group: Has the POSIX (system) group account

Samba SAM Accounts:
	/etc/samba/passdb.tdb
or	/usr/local/samba/lib/private/passdb.tdb

The use of 'pdbedit -i tdbsam -e ldapsam' can be used to migrate the 
SambaSAMAccount infromation to LDAP, but the migrationm of the POSIX accounts 
is a little more difficult.

The procedure you could use is to use the PADL migration tools to migrate the 
POSIX accounts to LDAP first, then use the pdbedit tool to migrate the 
SambaSAMAccount information. Alternately, check http://idealx.org and 
http://www.padl.com for the suitable migration tools that may permit the 
migration as a one-step operation.
