1 master many slaves

[Joao Pereira <joaopedro17@netvisao.pt>]

Hello i'm trying to create a network of ldap servers, with 1 master and 
some slaves, but i have 1 problem. is it possible to query a slave to 
add a new entry and the slave says to the master that is something to 
write and the master do it???
Maybe i didnt explain correctly.
i say to /slaveA/ to add a new user, the /slaveA/ contacts the /master/ 
just sending the request. /Master/ then writes in is directory the new 
user and *slurp* put it in the slave. this is what i meant to say.
Thnx for the help
