[Samba] idmap backend problems

 I disagree.   According to the Release Notes the idmap_rid does NOT
require an LDAP server.  The way I understand it is uses the last part
of your SID to derive what your UID will be, thus you will have
consistancy across your Sambas.

I compiled my samba the same way and it is working however I am
encountering problems with the winbind daemon while in this mode.  I
have submitted another topic on this problem.

Did you setup your /etc/nsswitch.conf file ?

Not so much, you're on the right path tho.  The idmap is primarily to
give a mapping between unix uids and windows SIDs when the users come
from an AD system or something of that nature.  Basically if you don't
have real unix users you use winbind and idmap to get it done... if I
understand correctly.  I don't use either.

That's essentially what you need to do unfortunately.  You need to store
the mapping someplace globally accessable for both machines to read it.

I see the light bulb going off in your head WRT storing the idmap file
on an nfs mount or some other shared filesystem, don't do it, it won't
