[Samba] RID idmap backend: difficulties looking up a user by its uid

[Jakob Ahlin]

Thanks for your answer, Dale. You were right, I had that line wrong. 
However, I think it just affected what uids the users would get, because 
the problem remains.
I have configured the TDB, LDAP and AD backends successfully; only the 
RID backend gives me the problem I explained in my original message.

I tried using the "idmap config" directive as well...
   idmap backend = tdb
   idmap uid = 1000000-1000010
   idmap gid = 1000000-1000010

   idmap config WBLABB : backend  = rid
   idmap config WBLABB : range    = 10000 - 1000000
   winbind use default domain = yes

...with the same result, i.e I need to retrieve the "passwd" entry by 
username before I can do the reverse.
