Starting with OpenKM 5.0.4 we added more "users by role" and "roles by user" configuration properties:

principal.ldap.users.by.role.search.base=cn={0},cn=users,dc=weyler,dc=local
principal.ldap.users.by.role.search.filter=(objectclass=group)
principal.ldap.users.by.role.attribute=member
 
principal.ldap.roles.by.user.search.base=cn={0},cn=users,dc=weyler,dc=local
principal.ldap.roles.by.user.search.filter=(objectClass=person) 
principal.ldap.roles.by.user.attribute=memberOf
