Code

1) updated ipc.c NetUserGetInfo - load \\%L\%U instead of \\%L\HOMES

Browse Source 
because the share must be browseable by a w95 client

2) send_mailslot_reply - unique or group datagram argument added.

3) netlogon.c - rewrote response packet to do the right thing for w95.

4) server.c reply_nt1() - added OEMDomainstring to the end.

5) (deep breath) reworked the nmbd-browsing code a little bit.
   i discovered two months ago that becoming a primary domain controller
   (and domain master browser) is done independently of becoming a
   backup domain controller (logon server) is done independently of
   becoming a local master browser.

   therefore, three sets of state-machines (instead of just one) are in
   place - each of which is responsible for taking samba through the
   required stages to become:  a logon server; a domain master browser;
   and a local master browser.

   each of these three things can occur independently on each interface,
   _including_ the wins pseudo-interface.  the only slight caveat is that
   the wins pseudo-interface, by virtue of _not_ being a broadcast
   interface, does _not_ register as a local master browser with the wins
   server, as this doesn't make sense.

usri11_auth_flags specifies the account operator privileges. The
possible values are:
Name Value Description
AF_OP_PRINT 0 Print operator
Leach, Naik [Page 28]
INTERNET-DRAFT CIFS Remote Admin Protocol January 10, 1997
AF_OP_COMM 1 Communications operator
AF_OP_SERVER 2 Server operator
AF_OP_ACCOUNTS 3 Accounts operator
usri11_password_age specifies how many seconds have elapsed since the
password was last changed.
usri11_home_dir points to a null terminated ASCII string that contains
the path name of the user's home directory.
usri11_parms points to a null terminated ASCII string that is set
aside for use by applications.
usri11_last_logon specifies the time when the user last logged on.
This value is stored as the number of seconds elapsed since
00:00:00, January 1, 1970.
usri11_last_logoff specifies the time when the user last logged off.
This value is stored as the number of seconds elapsed since
00:00:00, January 1, 1970. A value of 0 means the last logoff
time is unknown.
usri11_bad_pw_count specifies the number of incorrect passwords
entered since the last successful logon.
usri11_log1_num_logons specifies the number of times this user has
logged on. A value of -1 means the number of logons is unknown.
usri11_logon_server points to a null terminated ASCII string that
contains the name of the server to which logon requests are sent.
A null string indicates logon requests should be sent to the
domain controller.
usri11_country_code specifies the country code for the user's language
of choice.
usri11_workstations points to a null terminated ASCII string that
contains the names of workstations the user may log on from.
There may be up to 8 workstations, with the names separated by
commas. A null strings indicates there are no restrictions.
usri11_max_storage specifies the maximum amount of disk space the user
can occupy. A value of 0xffffffff indicates there are no
restrictions.
usri11_units_per_week specifies the equal number of time units into
which a week is divided. This value must be equal to 168.
usri11_logon_hours points to a 21 byte (168 bits) string that
specifies the time during which the user can log on. Each bit
represents one unique hour in a week. The first bit (bit 0, word
0) is Sunday, 0:00 to 0:59, the second bit (bit 1, word 0) is
Leach, Naik [Page 29]
INTERNET-DRAFT CIFS Remote Admin Protocol January 10, 1997
Sunday, 1:00 to 1:59 and so on. A null pointer indicates there
are no restrictions.
usri11_code_page specifies the code page for the user's language of
choice
All of the pointers in this data structure need to be treated
specially. The pointer is a 32 bit pointer. The higher 16 bits need
to be ignored. The converter word returned in the parameters section
needs to be subtracted from the lower 16 bits to calculate an offset
into the return buffer where this ASCII string resides.
There is no auxiliary data in the response.
