Hi all,

with this version, as in 4.0.5, i have always the windbind crash after
wbinfo --uid-info 3000000
or
ls -la sysvol/

my system 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux

I already post here some information (no problem with 4.0.4, found last stable patch with bisect), could someone help me ?

thanks and regards

philippe

Hi

You might try getting hold of one of the Samba developers on IRC and asking
them about this.

Hi
It fails when the file system doesn't support acl's. It's one of those
were it's both a uid and a gid:

wbinfo --sid-to-name=S-1-5-32-544
BUILTIN\Administrators 4
wbinfo --sid-to-uid=S-1-5-32-544
3000000
wbinfo --sid-to-gid=S-1-5-32-544
3000000

ls -la /usr/local/samba/var/locks/sysvol

Copy and make executable the following script into
/usr/local/bin/gdb_backtrace
You can add the line panic action = /usr/local/bin/gdb_backtrace

It should give you a backtrace when winbindd is crashing, post this
trace to samba-technical list.
