Behavior Differences Between HP CIFS
Server A.01.* and A.02.01
Many known changes in behavior between HP CIFS Server A.01.*, based
on Samba 2.2, and HP CIFS Server A.02.01, based on Samba 3.0, might
affect your HP CIFS Server operation. This section describes significant
changes in behaviors for HP CIFS Server A.02.01. For additional
changes and details, refer to /opt/samba/SAMBA_WHATSNEW.txt.
The major changes in behaviors for HP CIFS Server A.02.01 are as
follows:
• HP CIFS Server system resource requirement has been increased
The HP CIFS Server A.02.01 requires 1000 KB per smbd process.
In addition to the base memory increase, a single smbd process may
temporarily use up to 4 MB of memory swap space.
The nfile number increases from 24 to 28 entries per smbd process.
Refer to the Chapter 2, “Installing and Configuring HP CIFS
Server”, and Chapter 14, “HP -UX Cconfiguration for HP CIFS” in
the HP CIFS Server Administrator’s Guide for details.
• As of the A.02.01, the smb.conf variable strict locking default
has been changed to yes.This changes the Samba locking behavior
to check for locks on every read and write, which may affect
performance. If a change in performance is noticed, try setting
strict locking = no.
• When operating as a member of a Windows domain, A.01.* maps any
users authenticated by the remote domain controller to the guest
account if it can not obtain a UID via the getpwnam() call. A.02.01
simply rejects the connection as the NT_STATUS_LOGON_FAILURE
error.
• When adding machine accounts to an HP CIFS Server A.01.* acting
as a domain controller, you specify the add user script parameter
to create the HP-UX identity of the machine trust account. HP CIFS
Server A.02.01 introduces a new add machine script parameter
that must be specified for this purpose. A.02.01 does not fall back to
use the add user script option in the absence of an add machine
script option.
