set syntax on acl

[ML <ops@klez.it>]

I will try to understand the right syntax for set parameters, but I dont
find sample.
I have read this:
http://www.openldap.org/lists/openldap-software/200105/msg00270.html
http://www.openldap.org/faq/data/cache/1133.html
http://www.openldap.org/faq/data/cache/1134.html

and I write this acl but it dosnt work :((
am I wrong?

access to dn.regex="jvd=([^,]+),o=hosting,dc=example,dc=tld$"
        by self write
        by set="user/editAccounts & [true]" write
        by dn.exact="cn=phamm,o=hosting,dc=example,dc=tld" read
        by * none

I think that the postmaster can search and write on the dn children

his dn 
cn=postmaster,jvd=example.tld,o=hosting,dc=example,dc=tld
editAccounts=true


Thanks in advance

My slapd is 2.1.30-3
