Description Michael Letzgus-Koppmann 2012-07-31 20:39:46 UTC 
Message:
cache_traverse_validate_fn: key length too large: (1029) > (1024)

In the tdb dump I've found this entry: key(1029) = "NDR/AD/2/\..."
So there really is a long key.

After removing the cache.tdb there is no such long entry, even after
enumerating/listing all groups (~2000) and users (~30000).

In both cases (database with an without the long key) "smbcontrol winbindd
validate-cache" says: Winbindd cache is valid.

Created attachment 7731 [details]
Allow larger keys for NDR keys, modified calculation for UA keys

Allow larger keys for non delivery reports (8*max_key_len)
Modified calculation for UA-Keys (1024*max_key_len)

After applying this patch no problems occur with my "faulty" winbindd_cache.tdb
