timeout. If we're running with SEC_ADS and we don't get a cldap response from the server when querying its name, don't fall back to NetBIOS requests as they're unlikely to succeed.

2012-05-22Fix bug #8953 - winbind can hang as nbt_getdc() has no timeout.Jeremy Allison1-1/+1
Add a timeout_in_seconds parameter to nbt_getdc() to make it fail after that time with NT_STATUS_IO_TIMEOUT.

2012-02-16Rename obscure defined constants.Christopher R. Hertel (crh)1-1/+1
Replaced the undescriptive SMB_PORT1 and SMB_PORT2 defined constants with the slightly more descriptive names NBT_SMB_PORT and TCP_SMB_PORT. Also replaced several hard-coded references to the well-known port numbers (139 and 445, respectively) as appropriate. Small changes to clarify some comments regarding the two transport types.

2012-02-10s3-winbindd: set the can_do_validation6 also for trusted domainMatthieu Patou1-0/+2
The flag can_do_validation6 was only set for the domain to which winbindd is the member. Setting this flag in other domains (trusted domain) if it's active directory domain is a good idea as it allow to do level 6 validation also when winbindd is querying them directly.

2011-04-29s3: In winbind, close parent/child socketsVolker Lendecke1-1/+1
This should further reduce fd load in winbind children
2011-04-28s3: Close the winbind client fds after forkingVolker Lendecke1-0/+10
In an overload situation, the winbind helper child process inherits all those hundreds of fd's which it will never talk to. Close them. We (Christian Ambach and me) just saw a crash in libkrb5. Christian's analysis showed that libkrb5 also does select, probably exceeding FD_SETSIZE and crashing due to that reason. The parent winbind in theory does not do Kerberos at all, so this should fix that problem. The crash is interesting because the child process did not really crash. Somewhere in glibc backtrace() is called, probably due to an assert() or some explicit consistency check. This then somehow generates a signal probably due to corrupted memory structures. That signal triggers Samba to again call backtrace(). This blocks hard on a ptrace_once(). Sorry for the long backtrace here, but this *is* interesting. The child process blocking and not really crashing makes the situation worse: The parent process does not get told the child has crashed and more client sockets pile up. This patch is intended to put some relief on this problem by closing the majority of sockets the parent holds.
