Step 4: provision Samba4
------------------------
-The "provision" step sets up a basic user database. Make sure your smbscript
-binary is installed in a directory listed in your PATH environment variable.
-It is presumed it's available just like any other commands from your shell.
+The "provision" step sets up a basic user database.
Must be run as a user with permission to write to the install directory.
::
# cd source
- # ./setup/provision --realm=YOUR.REALM --domain=YOURDOM \
+ # bin/smbpython ./setup/provision --realm=YOUR.REALM --domain=YOURDOM \
# --adminpass=SOMEPASSWORD --server-role='domain controller'
-REMINDER: Add the "bin" directory of the path you installed to
- (e.g. /usr/local/samba/bin) to your path, or the provision command
- will not work.
+REMINDER: Use the path to smbpython, as the provision command
+ will not work with the system python.
'YOURDOM' is the NT4 style domain name. 'YOUR.REALM' is your kerberos
realm, which is typically your DNS domain name.

Currently ldb is completely lacking in programmer or user

with the public functions declared in <a

+href="http://samba.org/ftp/unpacked/ldb/tools/">tools
directory</a>. Documentation in the same docbook format used by Samba
would be preferred.
ldb does not currently have its own mailing list or bug tracking
system. For now, please use the <a
