anonymize data

Hi all,

I have a question anonymizing data. My openldap have some confidential data inside and I would like this : if a person has a flag confidentiality set to 1 (or is in a special ou), openldap will replace or answer a different data.

For example :

if we request "sn" on this record , it will reply "Smith" dn: cn=Smith,ou=public,c=com confidentiality: 0 sn: Smith

if we request "sn" on this record , it will reply "XXX" dn: cn=Bond,ou=public,c=com confidentiality: 1 sn: Bond

I'm not sur Openldap can offer this kind of functionnality. Thanks for your help !
