#2922 ID mapping - bug in computing max id for slice range
Closed: Fixed Opened by preichl.

Closed: Fixed
Reopen Issue

There seems to be a bug in the way we assign ranges for domain when we algorithmically perform id mapping.

In sss_idmap_calculate_range() we compute the upper limit for ids max as being 'min + range' which means that actual range of ids is:

max - min + 1 = min + range - min + 1 = range + 1

And this differs from range by 1.

We should be even be able to see some mapping issue with secondary ranges. The last POSIX ID from a range and the first POSIX ID from the next range should return the same SID/RID.

In the IPA code there is 'range.max = r->base_id + r->id_range_size -1;' We should amend code to the same.

If there's seems to be a bug could you write unit test which will fail? TDD way.
