with 1.10.8 do you still get nt domain integration for accounts (in
pserver mode)?

right i think this is a failing of cvs (not cvsnt) but if cvsnt could work
around it that would be great.

this is where i start to get confused, especially with the impersonation
stuff.  i don't care about ntserver, i have unix and 95/98 clients that
needs access and if i understand correctly ntserver will not work at all
in that model.

so i need pserver with domain integration (since that's the whole reason
we want to move to cvsnt).  however any domain user that is created has
full access to all the repositories unless you can implement file systems
permissions.  right?

now i thought that with pserver and ntserver impersonation turned on, i
got a system where file system permissions could be implemented to control

if this doesn't work how do you control access to your repositories?

ugg, yeah, that's a pain.  we just use stunnel.  it's not as secure as ssh
but you can use cvs' account database and nothing is plain text.

okay so more questions.  what are the SANDBOX, HOME and TEMP variables
that i'm supposed to set actually used for?

yah, our data is important.

thanks for all the info.
