I think its caused by a rpc operation failing and us giving invalid
data back to the cache layer. Using talloc_zero() should solve this.

winbind default domains, particulary now I understand whats going on a lot
better. This ensures that the RPC client code does as little 'magic' as
possible - this is up to the application/user. (Where - for to name->sid code
- it was all along). This leaves the change that allows the sid->name code to
return domains and usernames in seperate paramaters.

smbd, and also makes it much cleaner inside winbindd.
It is mostly my code, with a few changes and testing performed by Alexander
Bokovoy <a.bokovoy@sam-solutions.net>. ab has tested it in security=domain and
security=ads, but more testing is always appricatiated.
The idea is that we no longer cart around a 'domain\user' string, we keep them
seperate until the last moment - when we push that string into a pwent on onto
the socket.
This removes the need to be constantly parsing that string - the domain prefix
is almost always already provided, (only a couple of functions actually changed
arguments in all this).
Some consequential changes to the RPC client code, to stop it concatonating the
two strings (it now passes them both back as params).
I havn't changed the cache code, however the usernames will no longer have a
double domain prefix in the key string. The actual structures are unchanged
- but the meaning of 'username' in the 'rid' will have changed. (The cache is
invalidated at startup, so on-disk formats are not an issue here).

(various e-mails announcements merged into some form of commit message below:)
This patch which adds basics of universal groups support
into Samba 3. Currently, only Winbind with RPC calls supports this, ADS
support requires additional (possibly huge) work on KRB5 PAC. However,
basic infrastructure is here.
This patch adds:
1. Storing of universal groups for particular user logged into Samba
software (smbd/ two winbind-pam methods) into netlogon_unigrp.tdb as array
of uint32 supplemental group rids keyed as DOMAIN_SID/USER_RID in tdb.
2. Fetching of unversal groups for given user rid and domain sid from
netlogon_unigrp.tdb.
Since this is used in both smbd and winbindd, main code is in
source/lib/netlogon_uingrp.c. Dependencies are added to AUTH_OBJ as
UNIGRP_OBJ and WINBINDD_OBJ as UNIGRP_OBJ.
This patch has had a few versions, the final version in particular:
Many thanks to Andrew Bartlett for critics and comments, and partly
rewritten code.
New:
- updated fetching code to changed byte order macros
- moved functions to proper namespace
- optimized memory usage by reusing caller's memory context
- enhanced code to more follow Samba coding rules
Todo:
- proper universal group expiration after timeout

when they are added or removed on the PDC.
- renamed GETPWNAM_FROM_{UID,USER} constants and functions to GETPW{NAM,UID}
- renamed GETGRNAM_FROM_{GID,GROUP} constants and functions to GETGR{NAM,GID}
- use SIGUSR2 in winbindd for debugging/logging instead of SIGUSR1 in
preparation for moving to smbcontrol type messages (not sure whether to
ditch this altogether or not)
- tidy debugging messages in top level winbind user and group routines
- convert talloc_init() to talloc_init_named()
- make enumerations of the domain list use the same local variable names

I tried testing this by lowering the buffer size in
cli_samr_enum_dom_groups() but that didn't work - I think this needs
more looking into

consistent backends (like ADS) always give correct primary group
info, so we can play cache tricks to speed things up a lot
inconsistent backends (like MSRPC) need to fetch stuff more often
(This used to be commit 217c39f23282e20f96a61a0d5a2434b3f5f66a86)

the backends
at startup, loop until we get the domain sid for our primary domain,
trying every 10 seconds. This makes winbindd handle a room-wide power
failure better

this one looks like just another winbind backend, and has the
following properties:
- does -ve and +ve cacheing of all queries
- can be disabled with -n switch to winbindd
- stores all records packed, so even huge domains are not a problem
for a complete cache
- handles the server being down
- uses sequence numbers for all entries
This fixes a lot of problems with winbindd. Serving from cache is now
*very* fast.

sequence number via ldap when using ads

now do searches on SID. This allows me to do a true ldap sid_to_name()
function
one one function to go!

I spent quite a while trying to work out how to make this call
via ldap and failed. I then found that MS servers seem use rpc
for sid_to_name, and it works even when in native mode, I ended
up just implementing it via rpc

also created winbindd_rpc.c which contains the functions that
have been converted to the new structure. There will soon be
a winbindd_ads.c for the ldap backend
