There's no builtin way to publish CIFS partitions, or their respective ACLs, to AD. So you need to publish it yourself. There's basically two options:
Publish it in AD. This requires extending the schema, i.e. creating a cIFSPartition class with two attributes, path and users. You would then have to find a Java library that can perform LDAP queries (I see a lot of questions about Spring LDAP here). You would probably need to make a webpage to help create and manage these cIFSPartition objects.
Store it on the webserver. You have lots of options here, like a text file or database. This way, you don't have to worry about LDAP.
