SID mapping: Samba and SSSD
...options/samba I could be wrong on this, but generally speaking, you can be compatible using idmap_rid if you set a low range identical to that of the low range in SSSD. SSSD determines low range for initial id slice using approximately the following algorithm IIRC: ``` uint32_t hash_val = 0; int our_slice = 0; int max_slices = 10000; int final_value = 0; int slice_size = 20000 hash_val = murmur3(sid_str, strlen(sid_str), 0xdeadbeef); our_slice = hash_val % max_slices; final_value = our_slice * slice_size +slice_size; ``` This works for the first slice, but slices after that are non-deterministic.

...there could be a problem because SSSD allows multiple slices.
