objectSid to uidNumber mapping

[Sad Clouds <cryintothebluesky [at] gmail.com>]

Does anyone know why nslcd requires you to specify the actual SID number:

map  passwd  uidNumber  objectSid:S-1-5-21-3623811015-3361044348-30300820

This is rather awkward and seems to be completely unnecessary. SID
numbers have a well defined format, so would it not be easier to
retrieve this number and automatically convert it to Unix uidNumber,
similar to what SSSD does? The configuration would be:

map  passwd  uidNumber  objectSid

Any ideas?
