- but another problem occured now
- the setup worked nice yesterday evening unitl ist stoppen working
- as I tried a login this morning it didn't work anymore
- if I try a "getnet passwd <user>" I get nothing back
- no login via pam_winbind is possible
- But I see a winbind core-dump in the logs:

- I then did a "wbinfo -u" and "wbinfo -g"
- both worked normally
- afterwards "getent passwd <user>" an pam-login worked again
- but only for a few minutes then the same happend again

- there's also this error in the logs I don't understand
- but it seems not to be directly related to the core dump

- Any Ideas what I can do now?
- should I post more information as my pam.d files?
- Is this a config issue or should I open a bug report?
