A map entry, also referred to as a mapping, uses the following format:
key location [ container ]
key is a user name, location is the fully qualified path for the user's home directory, and container is an optional AD container.
If you intend to publish the share in AD, you must specify an AD container name, which is specified as a comma-separated list of attribute name-value pairs. The attributes use the Lightweight Data Access Protocol (LDAP) distinguished name (DN) or relative distinguished name (RDN) format.
The DN or RDN must be specified in LDAP format by using the following attribute types:
cn= represents the common name
ou= represents the organizational unit
dc= represents the domain component
The attribute type that is used to describe an object's RDN is called a naming attribute.
AD uses the naming attributes as follows:
cn for the user object class
ou for the OU (organizational unit) object class
dc for the domainDns object class
