around failed query_user calls. This fixes
logons to a member of a Samba domain as a user from a
trusted AD domain.
As per comments on samba-technical, I still need to add
(a) cache the PAC info as werll as NTLM net_user_info_3
(b) expire the cache when the SMB session goes away
Both Jeremy and Guenther have signed off on the idea.
logons work if the client gives the MSV1_0_ALLOW_SERVER_TRUST_ACCOUNT
or MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT flags. This changes
the auth module interface to 2 (from 1). The effect of this is
that clients can access resources as a machine account if they
set these flags. This is the same as Windows (think of a VPN
where the vpn client authenticates itself to a VPN server
using machine account credentials - the vpn server checks
that the machine password was valid by performing a machine
account check with the PDC in the same was as it would a
user account check. I may add in a restriction (parameter)
to allow this behaviour to be turned off (as it was previously).
That may be on by default.
Andrew Bartlett please review this change carefully.

We were filling in our name as the server which processed the login, even
when it was done by a trusted DC.
Thanks to John Janosik <jpjanosi@us.ibm.com> for the fix.

This re-enables the Samba 2.2 behavior where a user that was
successfully authenticated by a remote DC would be mapped
to the guest account if there was not existing UNIX account
for that user and we could not create one.
Vince Brimhall <vbrimhall@novell.com> - slight tidyup by me to
use Samba conventions.
Vince - thanks a *lot* for this code - please test to make sure
I haven't messed anything up.

* rewrote the tdb layout of privilege records in account_pol.tdb
(allow for 128 bits instead of 32 bit flags)
* migrated to using SE_PRIV structure instead of the PRIVILEGE_SET
structure. The latter is now used for parsing routines mainly.
Still need to incorporate some client support into 'net' so
for setting privileges. And make use of the SeAddUserPrivilege
right.
(based on Simo's code in trunk). Rewritten with the
following changes:
* privilege set is based on a 32-bit mask instead of strings
(plans are to extend this to a 64 or 128-bit mask before
the next 3.0.11preX release).
* Remove the privilege code from the passdb API
(replication to come later)
* Only support the minimum amount of privileges that make
sense.
* Rewrite the domain join checks to use the SeMachineAccountPrivilege
instead of the 'is a member of "Domain Admins"?' check that started
all this.
Still todo:
* Utilize the SePrintOperatorPrivilege in addition to the 'printer admin'
parameter
* Utilize the SeAddUserPrivilege for adding users and groups
* Fix some of the hard coded _lsa_*() calls
* Start work on enough of SAM replication to get privileges from one
Samba DC to another.
* Come up with some management tool for manipultaing privileges
instead of user manager since it is buggy when run on a 2k client
(haven't tried xp). Works ok on NT4.
The old #ifdef JRATEST-block was copying 16 bytes and thus overwriting
acct_flags with bizarre values, breaking a lot of things.
This patch is successfully running in a production environment for quite
some time now and is required to finally allow Exchange 5.5 to access
another Exchange Server when both are running on NT4 in a
samba-controlled domain. This also allows Exchange Replication to take
place, Exchange Administrator to access other Servers in the network,
etc. Fixes Bugzilla #1136.
Thanks abartlet for helping me with that one.
Guenther
abartlet, I'd like to ask you to take a severe look at this!
We have solved the problem to find the global groups a user is in twice: Once
in auth_util.c and another time for the corresponding samr call. The attached
patch unifies these and sends them through the passdb backend (new function
pdb_enum_group_memberships). Thus it gives pdb_ldap.c the chance to further
optimize the corresponding call if the samba and posix accounts are unified by
issuing a specialized ldap query.
The parameter to activate this ldapsam behaviour is
ldapsam:trusted = yes
Volker
In auth_winbind, remove the push_utf8 calls, as this is no longer a
UTF8 interface. (Removed from everywhere else earlier).
Tested with ASCII - I tried to load the weird charset for testing, but
it doesn't seem to work any more.
Andrew Bartlett
setups on its way to open a pipe. This gets rid of many round-trips to the
LDAP server during logon by setting up the server_info_guest once and not
asking the LDAP server and nss every time. Make sure that the ldap connection
is reopened in the child. (I did not look at the sql backends.)
Volker
Use the fully qualified DOMAIN\user format for 'security = domain|ads'
and apply after authentication has succeeded.
* also change fill_domain_username() to only lowercase the username
and not the domain+username. This was a cosmetic fix only.
makes the output more consistent with %D and %U.
On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork().
For other systems, we now only re-seed after a fork, and on startup.
No need to do it per-operation. This removes the 'need_reseed'
parameter from generate_random_buffer().
