The ASU Version 5.1B-4 kit provides enhancements and corrections for problems
found in the ASU Version 5.1B-3 ECO2 software and in earlier versions of the ASU
Some of the enhancements and corrections in the ASU Version 5.1B-4 kit are:
See the ASU Version 5.1B-4
Release Notes for a complete list of new features, functionality, and
- A new registry parameter, StoreAclAsMetadata, enables the ASU server to
store file and directory ACLs directly in file system metadata. This is
particularly useful if the number of files with explicit ACLs has caused the ACL
database to grow extremely large (more than 1,000,000 ACLs or so).
- The ASU server can now be configured to use port 445 for SMB connections in
addition to ports 138 and 139. Configuring ASU to use port 445 is useful if any
Windows servers or clients in the network have been configured to use only port
445 for SMB connections.
- A new registry parameter, NoLMHash, can be used to disable the storage of
LAN Manager (LM) hashes of users' passwords in the SAM database. This enhances
security by preventing the ASU server from storing a weaker LM hash and allowing
only storage of the stronger NT hash of a user's password.
- The ASU server now enhances security even further in its authentication and
session security mechanisms by fully supporting the NTLMv2 protocol. This
protocol is enabled whenever the LMCompatibility registry parameter is set to
the value 3, 4, or 5.
- The "lmstat -c" command now displays the start time of the connection, the
logged-in domain and user name, the mapped UNIX user name, and whether or not a
NULL session has been established.
- The "asusetup" command on an ASU member server now updates member server's
SAM database to reflect the new PDC if the PDC of the domain has changed.
- The "nbtlookup" command has a new option, -a, to display the TCP/IP address
of the NetBIOS name. This option can be combined with the -h option to display
both the TCP/IP address and the TCP/IP host name of the NetBIOS name in a single
- The ASU server can now join a domain, using either the "asusetup" or "joindomain"
command, whose administrator account's password is longer than 14 characters.
You can install the ASU Version 5.1B-4 software on a system running the Tru64
UNIX Version 4.0F or higher operating system software. The ASU Version 5.1B-4

- Install the ASU software on a Tru64 UNIX system for the first time.
- Upgrade previous versions of the ASU software.
Note: You can no longer directly upgrade PATHWORKS for DIGITAL UNIX (Advanced
Server) to ASU. See the
5.1A ECO1 Release Notes for information on upgrading PATHWORKS for DIGITAL
UNIX (Advanced Server) to ASU.
