To me this sounds like an nsswitch issue. Reason being, if you have to
Official RPM install from said vendor, I'll bet that the old library
is being used.

check in /lib and /lib/security and find out if the libraries are the
old ones or not.

I do an MD5 on the files for comparison. Just for good measure (since I
am not using the official RPMs) I replace

/lib/libnss_windbind.so
/lib/libnss_wins.so
/lib/security/pam_winbind.so

I was having huge difficulty, I'd get incomplete responses from the AD
controllers, or winbind would crash. So, I just looked around at all the
files that are compiled in the samba source dir... I noticed them thar
liberaries being stubburn sonuvaguns. I dun copied over 'em with the new
ones and dadgummit, things shoor did start dancing.

At least for me, that solved the problems I had that were similar.

Please try this patch :


Succes, well sort off

This patch works for me as well. I can no longer crash winbindd by  
running

getent passwd

However my auth.log file still contains
write to socket failed!

But just a few seconds later it appears to be working, but it does  
not work.

And the user complains that subversion update through apache2 through  
pam authentication through winbind to win 2003 server does not work.

TortoiseSVN does no longer ask for username/password.

A restart of winbindd did not help, i had to restart apache2 as well  
before it would work.


After this restart i tried repeating the error by running getent  
passwdbut i can

nolonger get write to socket failed!messages in auth.log.

Re: [Samba] Samba 3.0.20a and Winbind crashing (bug?)

2005-10-10 Thread sysrm 
Yeah i forgot to mention that, i had the same problem in 3.0.14a as i do
in 3.0.20a :/

Mine doesnt freeze, it actually ends the daemon. whats odd (just noticed
this morning) is i checked the server at 7:40am, all is well. checked it
at 8.05 am, its crashed!

just had a look through logs etc, it looks like it crashes at 8am most

Any one else got any ideas?

 This sounds like the same problem i had with winbind in both 3.0.14
 abd 3.0.20.

 Mine freezes, and the daemon appears to be still running using ps and
 top,
 but it doesnt respond to queries.

 It seems like i can trigger this event by running getent passwd. It
 shows the
 accounts, but then the daemon dies.

 I run it on debian sarge, and i have another server with different
 hardware
 that also runs debian sarge. The other server does not have the problem
 (havent tested with getent passwd) but it does not see as many auth.
 attempts
 as the freezing server does. I use winbindd for pam_winbind.
 And some times it goes days without crashing other times it freezes
 several
 times an hour.

 I get this following entries in my auth.log:
  write to socket failed!
  internal module error (retval = 3



 I circumvented it by running wbinfo -p every minute and restarting
 winbbind if
 wbinfo failed.

There's a crash bug fix Jerry will be posting to the patches
