    Here are some notes on running MS-Access on a Samba drive from Stefan Kjellberg

    Opening a database in 'exclusive' mode does NOT work. Samba ignores r/w/share modes on file open.
    Make sure that you open the database as 'shared' and to 'lock modified records'
    Of course locking must be enabled for the particular share (smb.conf)

    The DEBUGADD() Macro

    In addition to the kludgey solution to the broken line problem described above, there is a clean solution. The DEBUGADD() macro never generates a header. It will append new text to the current debug message even if the format buffer is empty. The syntax of the DEBUGADD() macro is the same as that of the DEBUG() macro.

    The DEBUGLVL() Macro

    One of the problems with the DEBUG() macro was that DEBUG() lines tended to get a bit long. Consider this example from nmbd_sendannounce.c:

    -  DEBUG(3,("send_local_master_announcement: type %x for name %s on subnet %s for workgroup %s\n",

                 type, global_myname, subrec->subnet_name, work->work_group));
     

    One solution to this is to break it down using DEBUG() and DEBUGADD(), as follows:

    -  DEBUG( 3, ( "send_local_master_announcement: " ) );
    -  DEBUGADD( 3, ( "type %x for name %s ", type, global_myname ) );

    +  DEBUGADD( 3, ( "for workgroup %s\n", work->work_group ) );

    Note: in between request and response, calculate the client credentials, and check them against the client-calculated credentials (this process uses the previously received client credentials).

    Note: you must take a copy of the client-calculated credentials received here, because they will be used in subsequent authentication packets.

    LSA Server Password Set

    Note: the new password is suspected to be a DES encryption using the old password to generate the key.

    Note: in between request and response, calculate the client credentials, and check them against the client-calculated credentials (this process uses the previously received client credentials).

    Note: the server credentials are constructed from the client-calculated credentials and the client time + 1 second.

    Discussion

    NetBIOS over TCP/IP

    Samba implements NetBIOS, as does MS Windows NT / 200x / XP, by encapsulating it over TCP/IP. MS Windows products can do likewise.

    Every so often someone will come along with a great new idea. Storing of user accounts in an SQL backend is one of them. Those who want to do this are in the best position to know what the specific benefits are to them. This may sound like a cop-out, but in truth we can not attempt to document every nitty little detail why certain things of marginal utility to the bulk of Samba users might make sense to the rest. In any case, the following instructions should help the determined SQL user to implement a working system. -

    NAME MANGLING

    Samba supports "name mangling" so that DOS and Windows clients can use files that don't conform to the 8.3 format. It can also be set to adjust the case of 8.3 format filenames.

    There are several options that control the way mangling is performed, and they are grouped here rather than listed separately. For the defaults look at the output of the testparm program.

    All of these options can be set separately for each service (or globally, of course).

    The options are:

    mangle case = yes/no

    controls if names that have characters that - aren't of the "default" case are mangled. For example, - if this is yes then a name like "Mail" would be mangled. + aren't of the "default" case are mangled. For example, + if this is yes then a name like "Mail" would be mangled. Default no.

    case sensitive = yes/no

    controls whether filenames are case sensitive. If they aren't then Samba must do a filename search and match on passed names. Default no.

    default case = upper/lower

    controls what the default case is for new filenames. Default lower.

    preserve case = yes/no

    controls if new files are created with the case that the client passes, or if they are forced to be the - "default" case. Default yes. + "default" case. Default yes.

    short preserve case = yes/no

    controls if new files which conform to 8.3 syntax, that is all in upper case and of suitable length, are created - upper case, or if they are forced to be the "default" - case. This option can be use with "preserve case = yes" + upper case, or if they are forced to be the "default" + case. This option can be use with "preserve case = yes" to permit long filenames to retain their case, while short names are lowercased. Default yes.

    By default, Samba 3.0 has the same semantics as a Windows NT server, in that it is case insensitive but case preserving.

    NOTE ABOUT USERNAME/PASSWORD VALIDATION

It will log things that happen - when in daemon mode using the "machine name" smbmount, so + when in daemon mode using the "machine name" smbmount, so typically this output will end up in log.smbmount.
