[Samba] please wait for the user profile service...

[Evan Ingram]

hi all

got a windows 2008 server using samba as a primary domain controller.
also got terminal services on the windows box for remote desktops, got
some clients set up with thinstation to automatically connect to the
terminal server with rdesktop.

got a problem with logging on and off, its taking about 2 minutes to log
in, "please wait for the user profile service", time increases if theres
lots of users trying to log on at the same time.

has anyone had experience of this and can provide any assistance? does
it sound like a samba problem or a windows problem?
