Looking at that SID, the RID portion of it is is *really* large. The
last section there is 1153286127 (split up, that's 1,153,286,127).
Given that you've set an ldap_idmap_range_max of 1,000,000, this
pretty much explains why you can't convert this user. The conversion
of this should be 1153286127+100000 (your ldap_idmap_range_min is the
base, which leaves it at 1,153,386,127, which is FAR above the
1,000,000 you have allocated.
I'm at a loss to explain why some of your users have IDs in the
billion-RID range, but if you want these to be handled properly, I
think you're going to need to set the following values:
ldap_idmap_range_min = 100000
ldap_idmap_range_max = 2000100000
ldap_idmap_range_size = 2000000000
This will allow you to convert all entries in this domain. However,
because it requires reserving all 2 billion possible IDs for one
domain, you won't be able to handle a multi-domain forest.
I'd contact your Microsoft representatives to figure out why you have
entries with such high RID values.
I've resolved the issue with that - the original server I was
querying was returning bad SID data.
On another note, I'm slightly confused reading the man page on how
slices get assigned and used, and would like to understand it
further. For example, here's a clean start for SSSD, with
enumeration disabled, and the caches cleared. In other words, brand

When doing an "ID" on a user, the number that gets prepended to
their userid is not the slice numbers being shown above. It appears
to be "41" in this instance:
[root@server db]# id USER
The "65522" remains the same no matter how I edit the
idmap_range_max, but the numbers before them (41) change. What do
the slice numbers up above, and the "41" here, represent?
Thanks for your help!
