Package: winbind Version: 3.0.14a-3 Hi,
After the last upgrade of Samba/Winbind (a couple of days ago?), many errors are ocurring. The problem seems to be that winbind cannot lookup the groups on the w2k3 DC (native mode) for some reason. Samba is running in ADS mode and is a domain member server. This command works: wbinfo -t checking the trust secret via RPC calls succeeded As does this one: wbinfo -u Administrator Guest support_388945a0 Krbtgt etc... And this is where it crashes: wbinfo -g The process hangs (a kill -KILL is the only thing that works) and this mail gets sent to root: The Samba 'panic action' script, /usr/share/samba/panic-action, was called for pid 24851 (/usr/sbin/winbindd). Below is a backtrace for this process generated with gdb, which shows the state of the program at the time the error occured. You are encouraged to submit this information as a bug report to Debian.
