Hi All, I am reading the howto on samba.org, http://us3.samba.org/samba/docs/man/Samba-HOWTO-Collection/samba-pdc.html#pdc-example and find the section about SID/RID under Features and Benefits a little vague. It states that samba creates the RID, but it then states that the windows machine also allocates the RID. Here, *** The UNIX operating system uses a separate name space for user and group identifiers (the UID and GID) but Windows allocates the RID from a single name space. *** it says that windows allocates the RID, but just before that, it says, *** Samba produces the RID algorithmically *** Is that confusing, or is it just me?
