I am not shure, whether this is the right place, but the README wrote so ...

This is version 1.3 of the Hesiod distribution.

Problem description:
I use the hesinfo client on DEC RISC ULTRIX 4.3a (and on a current
Linux). The hesiod setup is the following:
rhs=.inf.tu-dresden.de
lhs=
(Please note that LHS is empty, this is contrary to the MIT Athena
Hesiod papers I read. Nevertheless this IMHO should be a valid mode
of operation.)
If i run 'hesinfo sr1 passwd', hes_to_bind (in hesiod.c) creates the
bindname sr1.passwd..inf.tu-dresden.de
Obviously this is wrong. The fix should explain the problem better
than I could.
Fix: (oops, the new file ist the first one ...)
