The Mailbox object class is exposed through LDAP as the "organizationalPerson" object class. This class represents an object that contains mail storage in the Microsoft Exchange system. One critical attribute on a Mailbox object is Assoc-NT-Account, which contains the security identifier (SID) of the Windows NT account that has access to the mailbox.
