If 'bobw' is in /etc/passwd and there is also a user in AD with the 
samaccountname 'bobw', then delete the one in /etc/passwd. You cannot 
have the same username in /etc/passwd and AD. If you add 'winbind use 
default domain = yes' to your smb.conf, then 'mydomain\bobw' will become 
just 'bobw'. For example, my record is in AD:

getent passwd rowland
rowland:*:10000:10000:Rowland Penny:/home/rowland:/bin/bash

You do not use usermaps any more, except for Administrator and yes, you 
may have to chown file ownership. There is a way around this though, but 
only if you have access to a domain DC, you give your users a uidNumber 
attribute and Domain Users a gidNumber attribute and then use the 
winbind 'ad' backend instead of 'rid'. You could use the IDs your users 
already have, if you want to go down this path, we can discuss this further.

Definitely not, as you have seen, Unix knows who I am, but 'cat 
/etc/passwd | grep rowland' returns nothing

Changing the idmap range would only be of use if the winbind 'ad' 
backend is used, the 'rid' backend calculates the ID from the user or 
groups RID.

Possibly, but I do not do mind reading ;-)
