with an attempt to register every 5 minutes. Once it successfully registers, it
will resume the 24 hours-per-refresh cycle.
WINS
WINS resolves NetBIOS names to IP addresses, and is used by the server to
communicate with CIFS clients on the network. NetBIOS (and by extension,
WINS) is not supported when multi-tenancy is enabled.
Note: WINS is deprecated in Windows 2008.
Directory services
The HNAS server supports the following directory service methods:
• Network Information Service (NIS)
• Lightweight Directory Access Protocol (LDAP)
These services associate identifiers with users, groups, devices, volumes,
folders, and other network resources. This functionality enables
Administrators to specify policies for access on a broad basis, rather than
explicitly on a per-resource basis, and to have this information accessible
throughout the network.
NIS (for NFS and FTP)
NIS databases provide simple management and administration of Unix-based
networks. These databases can provide details about users and groups, also
individual client machines (including IP address and host name, to facilitate
authentication for users logging in to clients on the network).
The server supports integration with NIS directory services which can provide
the following:
• NFS user and group account information retrieval
• Name services for resolving host names to IP addresses
• HNAS FTP user authentication
LDAP advantages
Many organizations are replacing their existing NIS infrastructure with the
more reliable, scalable and secure LDAP system. In addition to providing the
same services as NIS (user and group information retrieval, name service
resolution, and FTP user authentication), LDAP also provides the following
advantages:
• Improved accuracy, due to LDAP’s more frequent data synchronization of
current and replicated data.
