Description gary ng 2003-09-24 00:03:59 UTC 
I am testing a setup of samba 3.0(beta 2) PDC using OpenLDAP 2.1.21 as the 
backend. The samba part seems to be functioning alright and even wbinfo -a 
completes normally as expected. But there seems to be some problem in the 
libnss_winbind.so : I setup the pam.d/login to use pam_winbind and 
nsswitch.conf to use libnss_winbind. 
 
When I tried to login with the form of "login Domain\\user", pam_winbind 
completes as expected but libnss_winbind caused the winbindd panic. The panic 
code is as below :

It seems to be caused by libnss_winbind as if I omit libnss_winbind in 
nsswitch.conf, the daemon doesn't panic.
Comment 1 Gerald (Jerry) Carter (dead mail address) 2003-11-07 11:11:36 UTC 
please retest against 3.0.1pre2 (due out later today)
since beta2 is pretty old at this point and I have 
a feeling this has been fixed.
Comment 2 Gerald (Jerry) Carter (dead mail address) 2003-12-12 08:28:10 UTC 
reseting target milestone.  3.0.1 has been frozen.  WIll have to 
re-evaluate these.
Comment 3 Gerald (Jerry) Carter (dead mail address) 2004-03-18 10:07:48 UTC 
closing.  No feedback in several months.
Assuming the segfault has been fixed.
Comment 4 Gerald (Jerry) Carter (dead mail address) 2005-02-07 08:40:22 UTC 
originally reported against 3.0.0beta2.  CLeaning out 
non-production release versions.
Comment 5 Gerald (Jerry) Carter (dead mail address) 2005-08-24 10:15:27 UTC 
sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
Comment 6 Gerald (Jerry) Carter (dead mail address) 2005-11-14 09:24:10 UTC 
database cleanup
