username lookups against the Iowa State University hesiod
servers fails.  ISU uses HS class records in its database, rather
than the more common IN records.

libnss_hesiod apparently only successfully resolves for class IN
records.

To reproduce, use a hesiod.conf file containing the following
lines:

rhs=.IASTATE.EDU
lhs=.ns
#and alternately

classes=HS,IN

Do 'hesinfo deejoe password' with stand-alone hesiod (from MIT
for example, or the hesiod-3.0.2 rpm that is available via
rpmfind) the try 'id deejoe' with nsswitch.conf set to query
hesiod (assuming the username deejoe is not resolveable by some
other method specified in nsswitch.conf).  If stand-alone
hesinfo works, but id (using libnss_hesiod.so) doesn't, then
you've reproduced the problem.

This bug is preventing the incorporation of Mandrake 7.2 system
into the unified login scheme available to any of the ~40,000
users at ISU.

For a more detailed discussion, read down into this email from our
user's group archive.  Ignore the "I haven't tried this with
glibc-2.2" at the top of the message.  Later down in the same message,
Langasek indicates the results of trying it with glibc-2.2.
