	Hi, I don't understand what do you mean by saying 'how to architecture the final system?'. Are you saying about the configuration of the system that I'm going to run?
I'm thinking on a PIII 1GHz with 512MB RAM, RAID1 with 30GB SCSI. And a cluster of postfix servers doing frontend.


do you plain to use only the master ldap as backend ?
no replica's ?
what will you do if it blowes up ?
by 'architecture', I mean how many servers, how they communicate... etc

so you plane to have :

server 1 -----+--- frontend1
(ldap)  | postfix
+--- frontend2

I think it's not really safe, and your ldap server will have the load of many postfix servers....
what about something like :

ldap master --+--> replica1 -----+--------frontendS
| |
+--> replica2 -----+

where each frontend would have replica1, replica2,... in theire conf ?
the load on ldap server will be split on many replica's
Your master (where writes operations are done) will not have to take the load of reads operations.

do you think one box with postfix will be enought ?
If not, you'll have to dispatch the load. Then, you can easily create
replica's and share the load to multiple ldap servers. Of ourse, the
master will have to deal with 35000 entries read.write. but you will not
have so many writes a day, do you ?

Maybe you also need to consider another ldap server (netscape,... ?).
I just read some test saying that it was more stable.

Do you know how to architecture the final system ?

This is not solution, just clues.
