Hi Rowland,

     Just to let you know, we removed all the idmap entries we had on the smb.conf of our 
two DCs and the ids reported by getent passwd at the DCs were in the 3.000.000 range, as 
you said. We had to add back 'idmap_ldb:use rfc2307 = yes' to get the user listing with 
the original numbers on the DCs.

Here's what we commented out on the configurationfiles.

         # Default idmap config used for BUILTIN and local accounts/groups
         #idmap config *:backend = ad
         #idmap config *:range = 2000-9999

         # idmap config for domain E-TRUST
         #idmap config E-TRUST:backend = ad
         #idmap config E-TRUST:schema_mode = rfc2307
         #idmap config E-TRUST:range = 10000-40000
         #idmap cache time = 1
         #idmap negative cache time = 1
         #winbind cache time = 1
         idmap_ldb:use rfc2307 = yes
