The code that sets home directories (by placing them into 'getpwnam
responses') in winbindd strips out 'werid' characters, and replaces
them with an _.  I'm not sure if this correct behaviour, but when I
looked at changing it, it was more difficult than I had hoped.  (This
change could also break some notion of 'backward compatability').

pam_mkhomedir whould be trying to create the directory reported by
winbindd, and so *should* just create it with the _ and everything
should be fine.  That much is either a pam_mkhomedir bug, or a
misconfiguration.

However, if you had a username that was all 'werid' characters (like
in Japan), then a homedir of /home/DOM/_____ is not very useful.  So
please file a bug on this broken winbind behaviour, so we can look at
how to fix it.
