PAM: problem establishing PAM_RUSER

["Oliver Elphick" <olly@lfix.co.uk>]

Setting up dictd (1.4.9-2) ...
Restarting dictionary server: dictdsu: problem establishing PAM_RUSER
dpkg: error processing dictd (--configure):

What does this error mean?

And why does any attempt to do "su user" (where "user" is other than root)
result in diald's bringing up my Internet connection?
