ACL: write access allowed based on a user specific attribute

Hello all OpenLDAP users,

I'm quite new to LDAP and I need to modify a currently existing LDAP database. There exist users in the database which can authentify, and I would like to add a specific parameter on some of those users to enable write access to them (for the moment they only have read access) For example I currently have 2 users:

uid=user1,ou=Users,dc=myCompany,dc=fr uid=user2,ou=Users,dc=myCompany,dc=fr

I changed my schema in order to be able to define an attribute admin="TRUE" on user1. Now, I would like that only user1 could change anything in the database, and not user2. How would I do that ? Is it possible to define an ACL based on the attribute of a DN ?

Thanks
