 If you can;t change version you can probably borrow the code from there
 somehow. I think I also posted some code for 3.0.24 a few months ago
 that implemented a negative caching system with timeout, before we
 decided for the major rework.
 Search the archives.

Thanks a lot for your help, I found your patches 
(http://samba.org/~idra/patches/). Hmm, they are not what I would call small 
and nothing what I would like to test on a running system...

For now we will increase the connection timeout to winbindd, hopefully this 
will already help.

Thanks again,
Bernd

 Hi,
 
 we are running into a problem that winbindd sometimes caches negative
 entries into its tdb database. We are still investigating the reason for
 that.
 However, another question, when winbindd caches an entry into its tdb
 database, is there any timeout for those tdb entries? While walking through
 the code I don't see any relation between winbindd_cache.c and idmap_tdb.c.
 Is winbindd_cache.c only for memory related caching?
 
 If I would like to add a cache timeout to the tdb database, what would be
 the best approach?
 
 Thanks in advance,
 Bernd
 
 
 PS: We are still using samba-3.0.22, and for several reasons also don't want
 to update our customer systems.

In 3.0.25 we have reworked the idmap subsystem and we made available
both positive and negative cache timeouts for the cache (which is
separate from idmap_tdb itself now).

Simo.
