reconnect code to cope with rebooting a DC. This
replaces the code I asked Volker to revert.
The logic is pretty simple. It adds a new parameter,
"winbind reconnect delay", set to 30 seconds by
default, which determines how long to wait between
connection attempts.
To avoid overwhelming the box with DC-probe
forked children, the code now keeps track of
the DC probe child per winbindd_domain struct
and only starts a new one if the existing one
has died.
I also added a little logic to make sure the
dc probe child always sends a message whatever
the reason for exit so we will always reschedule
another connect attempt.
Also added documentation.
Jeremy.

was asking for a winbindd name to SID lookup of
"Unix Group\name" where "name" was also a valid username,
the winbindd passdb lookup of that name was losing the
domain string info before calling lookup name (ie. lookup_name()
was being called with just the string "name", not the
full string "Unix Group\name").
The passdb backend of winbindd has to cope with
not only names from it's own global SAM domain,
but it does lookups for BUILTIN and "Unix User"
and "Unix Group" also, so making it guess by
losing the domain string is "A Bad Idea" (tm) :-).
Note that as winbind globally calls winbind_off()
at startup, it's safe for winbind to call sys_getgrnam()
to do the "Unix Group" lookup from inside lookup_name().

should never include the user SID.
The comment for the function in winbindd/winbindd_ads.c says
/* Lookup groups a user is a member of. */
The following patch makes the wbinfo calls return the correct data
before and after a login.
wbinfo --user-domgroups and --user-sids

1. use the return value that idmap_tdb2_open_perm_db() gives us
2. don't delete frep the local db if deleting from the perm db failed.
3. fix wrong interpretation of return value of the local delete

This is a band-aid for the rather convoluted offline/online mess in winbind
right now. Winbind re-uses the offline functionality that is targeted at domain
client installations on laptops to not overload disfunctional DCs. It uses the
winbind cache timeout as the retry timeout after a DC reboot.
I am using a parametric options because when this mess is cleaned up, that
parameter needs to go away again.
I'd recommend to use something like
winbind:online check timeout = 30
in typical LAN environments. This means a reconnect is attempted every 30
seconds.

This was overwritten by "idmap uid/gid" anyway. These are now the range

in winbind
When a w2k3 DC is rebooted the 139/445 ports come up before the
udp/389 cldap port. During this brief period, winbind manages to
connect to 139/445 but not to udp 389. It then enters a tight loop
where it leaks one fd each time. In a couple of seconds it runs out of
file descriptors, and leaves winbind crippled after the DC does
finally come up

When SIGCHLD handling is delayed for some reason, sending a request to a child
can fail early because the child has died already. In this case
async_main_request_sent() directly called the continuation function without
properly removing the malfunctioning child process and the requests in the
queue. The next request would then crash in the DLIST_ADD_END() in
async_request() because the request pending for the child had been
talloc_free()'ed and yet still was referenced in the list.
This one is *old*...

In reloading the smb.conf, if a "log file" is specified in smb.conf,
winbind children will overwrite the logfile name to be the same as the
parent.

We must not return an error here just because we are offline.
We must instead fix the mappings to the best of our knowledge
(ie mark as mapped, expired ones, and as unmapped, unknown ones)
