To start you need to configure some file or/and the 389DS depending on 
how you store your aliases.
The easiest way is the flat file /etc/postfix/aliases
and you can configure le directive alias_maps = 
hash:$config_directory/aliases

A more sophisticated solution is to store aliases in 389DS, in this case 
you need to extend the scheme 389DS. You can find on the internet for 
postfix and ldap schemas like below works perfectly :
http://hannibal.solstice.nl/hannibalwiki/doku.php?id=hannibal:62postfix.ldif

Once 389DS configured with this scheme, you can set up aliases for 
postfix to use 389DS:
alias_maps = hash:$config_directory/aliases,  
ldap:$config_directory/ldap-aliases.cf
Where ldap-aliases.cf is a configuration file to find the alias in the 
LDAP server wich may contain the directive below :

server_host =   ldap://localhost/  ## ldap server on the same host
bind =          no
version =       3
timeout =       20
scope =         sub
search_base =   ou=Aliases,dc=example,dc=com
query_filter =  (mailacceptinggeneralid=%u)
result_attribute = maildrop
result_format = %u

entry "ou = Aliases, dc = example, dc = com" needs to be created on the 
server and the ldap entries with aliases.

Hope this helps
