The Unix ID for a RID is calculated this way:
<programlisting>
- ID = IDMAP UID LOW VALUE + DOMAINRANGENUMBER * RANGESIZE + RID
- - (MULTIPLIER * RANGESIZE)
+ ID = REDUCED RID + IDMAP RANGE LOW VALUE + RANGE NUMBER * RANGE SIZE
</programlisting>
+ where REDUCED RID = RID % RANGE_SIZE
+ and a DOMAIN RANGE INDEX = RID / RANGE_SIZE is used together with the
+ domain sid to determine the RANGE NUMBER (stored in the database).
</para>
<para>
Correspondingly, the formula for calculating the RID for a
given Unix ID is this:
<programlisting>
- RID = ID - IDMAP UID LOW VALUE - DOMAINRANGENUMBER * RANGESIZE
- + (MULTIPLIER * RANGESIZE)
+ RID = (ID - LOW ID) % RANGE SIZE + DOMAIN RANGE INDEX * RANGE SIZE
</programlisting>
- </para>
- <para>
- MULTIPLIER is calculated as FLOOR(RID / RANGESIZE).
+ Where the DOMAIN RANGE INDEX is retrieved from the database along with the
+ domain sid by the RANGE NUMBER = (ID - LOW ID) / RANGE SIZE .
