[Samba] rid_idmap_get_id_from_sid: no suitable range available for sid
Hello, I have the following message posted on the linux.samba newsgroup, but so far no response. Therefore I try again in this group, hoping that there are other people reading this group, and yes, that hopefully somebody can help me with my samba winbind problems.

So, it's clear now, that those SID's are not accidentely truncated, but are so by design. How does this fit in the Samba rid_idmap? Does anybody has a clue?? Regards, John Knappers Argentia B.V.
