HP CIFS Client A.02.02.03 Administrator's Guide

• Support for Microsoft Distributed File System (MS DFS)
• Support for Dynamically Loadable Kernel Module (DLKM)
• Support for SMB over TCP using port 445
CIFS UNIX Extensions
CIFS UNIX Extensions enable the CIFS Client and Samba server to implement standard UNIX file
system features. These include:
• UNIX permission modes
• File ownership based on UNIX UIDs and GIDs
• Symbolic links and hard links
• Standard UNIX timestamps for file access, change, and modification
• Includes other data contained in the UNIX stat(2) data structure
NOTE: This feature only works with CIFS servers that support CIFS UNIX extensions.
NTLM PAM Integration
NT LAN Manager (NTLM) is the default protocol by which CIFS clients are authenticated by CIFS
servers. When used in conjunction with HP's NTLM Pluggable Authentication Module (PAM) and
the HP CIFS Client, users who log in to an HP-UX system will have access automatically to
CIFS-mounted file systems provided that PAM NTLM and the CIFS server are using the same
database.
Kerberos Authentication: Integration with System Kerberos Cache
The CIFS Client supports the Kerberos authentication mechanism. Kerberos is a secure,
industry-standard authentication protocol. It provides significant improvements over the older NTLM
protocol traditionally used by CIFS Clients and Servers. The CIFS servers in your network must
support Kerberos in order for you to take advantage of Kerberos support in the HP CIFS Client.
Kerberos must be properly configured both on the HP-UX host on which the Client runs and on
your network.
An additional feature is that the HP CIFS Client is integrated with the system Kerberos cache. If the
HP-UX host uses PAM Kerberos or other Kerberos-aware programs that utilize the system Kerberos
cache, such as kinit(1) , the CIFS Client can utilize these cached credentials to provide automatic
access to mounted CIFS servers without explicit user-initiated authentication for each server.
AutoFS 2.3 Support for HP CIFS Client
The AutoFS is a service which is part of the HP ONC product set that automatically mounts or
unmounts filesystems with near- transparency to the end users. The latest version of AutoFS 2.3
supports the mount and unmount of the HP CIFS Client mounted filesystems. AutoFS 2.3 can
automatically perform direct and indirect mounts of the HP CIFS filesystems. AutoFS 2.3 only
supports the HP CIFS Client with direct and indirect map files, it doesn't support CIFS Client with
special or executable map files, or with multiple (replicated) servers.
In order to provide HP CIFS Client AutoFS support, AutoFS 2.3 must be installed and configured
on the system. For detailed information on installing and configuring AutoFS, please refer to
