Hi,
I'm looking for a bit of inspiration...
I have a number of linux boxes using winbind to provide UNIX system
users from a Win2008R2 Active Directory domain. I'm using winbind's
RID idmap backend thing to provide consistent UNIX UIDs and GIDs across
multiple servers. For non-windows people, the RID is a 32 bit integer
which uniquely identifies an object in a domain, and forms the right-
most part of the Active Directory forest-wide SID.
A SID looks like:
S-1-5-21-993118751-601841214-1674189692-1134
The RID, in the above case, is 1134.
My UNIX UIDs are always (RID + 1000).
I always thought unix uid (or at leaset linux) is unsigned short;
won't you run into problem at one point with this?
I understand that linux, since 2.4, supports 32 bit UIDs.
Not only supports, but has.
As are PIDs, FDs, etc. etc.
