read ACL working but write ACL not

[JOYDEEP <j.bakshi@unlimitedmail.org>]

Dear list,

Please see below my LDAP structure

base DN --->  *dc=suse,dc=ldap
virtual domain   ---> **virtualDomain=kolkata.opendingo.com,dc=suse,dc=ldap*
*user DN -->**ou=users,virtualDomain=kolkata.opendingo.com,dc=suse,dc=ldap
group DN --> **ou=groups,virtualDomain=kolkata.opendingo.com,dc=suse,dc=ldap
**contacts DN --->**
ou=contacts,ou=contacts,virtualDomain=kolkata.opendingo.com,dc=suse,dc=ldap
personal contacts
-->**ou=personal,ou=contacts,ou=contacts,virtualDomain=kolkata.opendingo.com,dc=suse,dc=ldap


here is my ACL to read and write personal addressbook. the read ACL is
working here but the write ACL is not working.

*################ personal ACL #######################
access to
dn.regex="cn=([^,]+),ou=personal,ou=contacts,ou=contacts,virtualDomain=([^,]+),dc=suse,dc=ldap$"
  by dn.exact,expand="uid=$1,ou=users,virtualDomain=$2,dc=suse,dc=ldap" 
read
  by * none

access to
dn.regex="cn=([^,]+),ou=personal,ou=contacts,,ou=contactsvirtualDomain=([^,]+),dc=suse,dc=ldap$"
  by dn.regex="uid=$1,ou=users,virtualDomain=$2,dc=suse,dc=ldap"  write
  by * none
#################################################

the log reports ****tag=105 err=50 text=no write access to parent**********
could any one suggest how to solve the problem ?
thanks
