ASU Version 5.1B-4 software
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 software.

Some of the enhancements and corrections in the ASU Version 5.1B-4 kit are:

  • 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 command.
  • 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.
See the ASU Version 5.1B-4 Release Notes for a complete list of new features, functionality, and corrected problems.

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 software can be used to

  • 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 ASU Version 5.1A ECO1 Release Notes for information on upgrading PATHWORKS for DIGITAL UNIX (Advanced Server) to ASU.
