Public bug reported:

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

Torsten
