2013-05-06s3:idmap:autorid: make calculation in idmap_autorid_sid_to_id much more obviousMichael Adam1-3/+6
This is my attempt to make the sid->unix-id calculation much more obvious. Especially with the introduction of the multi-range support an the originally named "multiplier", the calculation id = low_id + range_size * domain_number + rid - range_size * multiplier was rather opaque to me. What really happens here is this: The rid is split into a reduced_rid part that is < rangesize and a multiple of rangesize. This is given by the formula rid = rid % range_size + (rid / range_size) * range_size We define reduced_rid := rid % range_size and domain_range_index := rid / range_size ( == the original multiplier) and the original formula is equivalent to: id = reduced_rid + low_id + range_number * range_size; and reads id = reduced_rid + range_minvalue if we set range_minvalue := low_id + range_number * range_size.

2013-05-06s3:winbindd/autorid multiple range supportAbhidnya Joshi1-19/+36
when a mapping request for a RID comes in that is larger than the rangesize, allocate an extension range to be able to map this one This is especially important for large installations which might have large RIDs being used in a trusted domain that the administrator was not aware of when planning for autorid usage and so those objects could not be mapped up to now. As it is not possible to change the rangesize after the first start of autorid, this would lead to big trouble.

2013-05-03idmap: Store negative cache entries if the backend failsVolker Lendecke1-2/+2
This changes the behaviour for out-of-range queries: The tdb backend (probably all backends) returns NT_STATUS_NONE_MAPPED and does not set the map.status value to ID_UNMAPPED. This means that we did an early error exit, not setting a negative cache value. This makes smbd ask winbind over and over again for out-of-range gids, which can be a performance problem in certain scenarios. The new code makes us fall through to the code setting the negative cache entry in all cases.
