Samba 2.2.8a / SMBMXG3C

Streamlined Installation Layout (Some Files Have Moved)
Previous versions of Samba installed a few files into the SAMBA.SYS group and the remaining files into the
SAMBA account. Starting with Samba 2.2.8a, all files are now installed into the SAMBA account in a
version-specific group, (for example, SMB228A.SAMBA). The Samba 2.2.8a installation script does not modify
any of the old Samba files in the SAMBA.SYS group.
The Samba 2.2.8a installation script modifies the /usr/local/samba symbolic link to point to the new
/SAMBA/SMB228A file location. A new symbolic link of /SAMBA/CURRENT is created to point to the same
location.
If you have any jobs, UDCs or command files, and other references that point to the old SAMBA.SYS files, you
must modify these old references to point to the new file locations. Use either of the symbolic links to do this.
That is, instead of SMBD.SAMBA.SYS, you can refer to SMBD.CURRENT.SAMBA or /usr/local/samba/SMBD or
/SAMBA/CURRENT/SMBD.
Existing 2.0.7 Configuration Files are Compatibles with 2.2.8a
Your existing 2.0.7 configuration files are compatible with 2.2.8a. Copy them from the old/SAMBA/SMB207/lib
location to /usr/local/samba/lib or /SAMBA/CURRENT/lib.
In order to take full advantage of the new 2.2.8a functionality, it is recommended that you
use/usr/local/samba/lib/samp-smb.conf as a template for creating a new smb.conf file.
New "Full-Power" Model Enabled by Default
Previous versions of Samba for MPE required manually adding PM capability to the MGR.SAMBA user in order
to enable "full-power mode" where Samba can authenticate against traditional MPE user and account
passwords of the format USERPW,ACCTPW. This functionality is now enabled by default starting with
Samba2.2.8a.
Full-power mode is the recommended mode of operation. Besides the convenience of authenticating against
traditional MPE passwords, full-power mode also enables Samba to setuid() to the authenticated user so
that all file accesses occur with the authenticated user's access rights.
Full-power mode under Samba 2.2.8a is enabled for Samba program files if they are owned by MANAGER.SYS
but reside in the SAMBA account. The full-power program files are currently NMBD, SMBD, and SWAT. Since PM
capability on the MGR.SAMBA user is no longer required for full-power mode, it is removed by the Samba2.2.8a
installation script.
Migrating Back to Samba 2.0.7
If after installing Samba 2.2.8a, you decide that you want to migrate back to Samba 2.0.7, perform the
following steps:
:HELLO MANAGER.SYS
:PURGELINK /usr/local/samba
:NEWLINK /usr/local/samba,/SAMBA/SMB207
:ALTUSER MGR.SAMBA;CAP=+PM
(If you were previously using Samba 2.0.7 in full power mode.)
