The idea here is to eliminate the need to *set* the 'HWM' (High Water
Mark) in the tdb. Instead, each caller wanting to add an item to the
TDB uses the fact that an insert will *fail* if entry already exists.
More importantly, this means that we don't need to know the value of the
idmap uid/gid values when setting arbitrary entries, which can occur on
an smb.conf without such values specified.
Then all we need to do is loop until we get an id that will insert.
This means that the HWM does not need to be accurate, and we can have
IDs allocates safely above the HWM.
Setting the HWM to an arbitrary value was racy in the past - now we
don't even do it.
This patch also adds paranoia in reading the tdb - both the entry, and
it's reverse entry must be present. This means that we don't need to
'clean up' after an abnormal failure (which would probably fail too),
instead we rely on readers to ignore the half-completed entry. The way
this is done will allow SIDs to then allocated an ID when things are
normal again.

from the output of 'net idmap dump'.
'net idmap dump' now also prints the USER/GROUP HWM.

tested.
Incrementing HWW_USER while allocating a GROUPID looked somewhat wrong.

* remove 'winbind uid' and 'winbind gid' parameters (replaced
by current idmap parameter)
* create the sambaUnixIdPool entries automatically in the 'ldap
idmap suffix'
* add new 'ldap idmap suffix' and 'ldap group suffix' parametrer
* "idmap backend = ldap" now accepts 'ldap:ldap://server/' format
(parameters are passed to idmap init() function

The correct prototype in C is function(void).
Please remember this !

New objectclass named sambaSamAccount which uses attribute
prefaced with the phrase 'samba' to prevent future name clashes.
Change in functionality of the 'ldap filter' parameter. This always
defaults to "(uid=%u)" now and is and'd with the approriate objectclass
depending on whether you are using ldapsam_compat or ldapsam
conversion script for migrating from sambaAccount to
sambaSamAccount will come next.

few fixes to *id_to_*id functions, we don't set the mapping for algoritmic
RIDs, they are resolved in the classic way
eliminate getpw* calls from tdbsam

SAM_ACCOUNT does not have anymore uid and gid fields
all the code that used them has been fixed to use the proper idmap calls
fix to idmap_tdb for first time idmap.tdb initialization.
auth_serversupplied_info structure has now an uid and gid field
few other fixes to make the system behave correctly with idmap
tested only with tdbsam, but smbpasswd and nisplus should be ok
have not tested ldap !

fix debug, add "idmap" string to the list of classes
fix idmap, check init failures, and enhance debugging
fix idmap_tdb, _do_ init uid and gid low,high states (too bad I missed that
before)
fix smbd/uid.c, use gid_t for gids and uid_t for uids

places where it was used, this caused me segfaults in the last week :(

first run if idmap.tdb is not found, and then eventually convert it to the
new format.
This is done to unify winbind and idmap databases and to make a backup of
winbindd_idmap.tdb in case you want to downgrade (of course it will not be
updated).
This is needed because idmap.tdb contains also local mappings, not only
foreign domains mappings.
Added some other fixes/improvements
Simo.

includes a --with-idmap=no switch to disable idmap usage if you find
problems.
cosmetic fixes and param aliases to separate winbind from idamp roles.
A temporarily remote idmap winbind compatibility backend.
As I have time I will further change code to not call directly winbind
(partly done but not tested) and a specilized module will be built in place
for the current glue hack.
The patch has been tested locally in my limited time, the patch is simple and
clear and should not reserve problems, if any just disable it.
As usual, comments and fisex are welcome :-)
Simo.
