can't get back_meta/rewrite working

["Alejandro Mery" <amery@geeks.cl>]

Hi, i'll rephrase my problem

having three working bdb databases:
dc=client1
dc=client2
dc=client3

each with an ou=A,dc=$client
and i want to create a read-only virtual ou=A, to look like: dc=$client,ou=A

backend meta
...
database meta
rewriteEngine on

rewriteContext default
rewriteRule "(.*)dc=client1,ou=A$" "%1ou=A,dc=client1"
rewriteRule "(.*)dc=client2,ou=A$" "%1ou=A,dc=client2"
rewriteRule "(.*)dc=client3,ou=A$" "%1ou=A,dc=client3"

access to *
       by * read

what am i doing wrong?

TIA,
Alejandro Mery
