[Dovecot] Change mail_location for one user?

[Scott Galambos]

I tried something similar already.

passdb {
   driver = shadow
}

userdb {
   driver = passwd-file
   args = username_format=%n /path/to/passwd
}

With only the one sarah user defined in /path/to/passwd. But then all 
other users cannot log in anymore.  Thunderbird says "Sending of 
password did not succeed".  Does anyone know if specifying a userdb 
stops passdb/shadow from being used?  Do I need to copy all users from 
the passdb/shadow system to /path/to/passwd?  Was hoping to just specify 
single users I wanted to override in /path/to/passwd.
