samba - Feb 2008 - Winbind data (getent) not persistent?

Hi All,

I have one other question:

Why is the winbind data (getent) not persistent?  I have played with the
cache option in smb.conf file, but it does not seem to work.  I'd expect
this option to control the refresh interval of the AD data, but on my
Redhat AS 4.0 system it goes out every couple of minutes unless I write
a cron job that runs getent passwd and getent group every few minutes.
This caused me a big problem early on because I got locked out of my
system.  Is this a bug with winbind or am I missing some configuration
option on my system?

Thanks,

Brian Whyte
