You can use regex pattern substitution in the form:
access to dn=".*ou=([^,]+),o=myorganization"
by dn="cn=admin,ou=$1,o=myorganization" write
by * read
so, if you call "cn=admin,ou=customer X,o=myorganization"
the administrator of "customer X", then it can access
all data below "ou=customer X,o=myorganization"
