Sorry, but no, Samba does not store anything in AD if you use the 'rid'
or 'autorid' idmap backend. 
I take it you need to get Unix IDs on non domain joined machines, my
only suggestion would be to obtain the user or group objectSid
attribute, get the RID from that and calculate the ID using the
domain low range you use on Unix domain members.
