yes it is.  the imposition on samba of map files is ... painful, to say
the least.  it's causing problems.

most people, running without trusted domains, will be completely

some people _may_ want a MYSAMBASERVER\Administrator account in

hmm, good point, can think of horrible reasons for doing this, plus it's
not necessary: default domain is HOME anyway.

... hmm, smbpasswd is "local SAM database" accounts.  can do some
name-munging there.

for ROLE_DOMAIN_PDC, samdbname = domainname.  therefore, entries in
/etc/passwd would not have domainname in front of them.

for ROLE_DOMAIN_MEMBER and ROLE_STANDALONE, samdbname = wkstaname,
therefore for checking entries in smbpasswd against /etc/passwd, you'd
have to strip out WKSTANAME from the /etc/passwd name.
