[Bug 207791] Re: winbind forgets uid/name gid/name mappings in regulary periods

[Torsten Krah]

Beside natty i am seeing this on a fresh lucid install too.

error view (winbind did forget the name):

-rw-rwxr-- 1 11107 praktikanten  63K 2007-01-19 17:11 2006.xls
-rw-rwxr-- 1 11107 praktikanten 115K 2007-06-01 12:01 2007.xls

renewed the infos via `id myuser` (which is the one with UID 11107):

-rw-rwxr-- 1 myuser praktikanten  63K 2007-01-19 17:11 2006.xls
-rw-rwxr-- 1 myuser praktikanten 115K 2007-06-01 12:01 2007.xls

Title:
  winbind forgets uid/name gid/name mappings in regulary periods

Status in “samba” package in Ubuntu:
  Confirmed
Status in “samba” package in CentOS:
  New

Bug description:
  Binary package hint: winbind

  Version 3.0.26a-1ubuntu2.3, Gutsy.

  I am memeber of a domain, wbinfo -u and wbinfo -g are displaying users+groups fine.
  nssswitch isconfigured lile that:

  passwd:         compat winbind
  group:          compat winbind
  shadow:         compat winbind

  Using getent passwd "domainuser" does succeed, id "domainuser" too.

  However, after 10 minutes (this times varies), doing a "ls -l file" does only show the uid of the user/group, the names are non persistent anymore.
  I than have to do a manual refresh with getent or id (they succeed the first time) and it works again, username + groupnames are there.
  Thats really annoying because many tools and daemons are relying on persistent users/groups, not only the uids.
  Don't know why they get lost from time to time, but it happens everytime.
  Using nscd does not help.
  My workaround for now is to have a local copy in /etc/passwd, but not shadow, to have a persistent uid/name mapping.

  smb.conf winbind parameters:

          winbind cache time = 10
          winbind refresh tickets = true
          winbind enum users = yes
          winbind enum groups = yes
          winbind use default domain = Yes
          winbind offline logon = true

  Any things i can do, tweaks, changes or something?

  kind regards
