[Samba] workgroup > join domain with same name = no issue? I don't get it

[Michael Schmitt]

Hi list,

right now I run a test setup for samba as a PDC, nearly everything works
great but I have some issues / questions. One is related to the docs
(samba howto collection), there is stated that it is not a good idea to
have a local workgroup and create a domain with the exact same name and
join the windows boxes ther. It is said that this will fail or at least
it will have some problems. But here, what should I say, it worked like
a charm. I kicked the boxes again out of the domain, rejoind them,
purged the PDC stuff, restarted from scratch and tried it again, all the
time with the same domain / workgroup / local DNS domain.
As this is right now just testing I am a bit worried I may run into
preblems if I do this in production networks. Could someone elaborate on
this please?

regards
Michael
