System: NetBSD 1.5.3_ALPHA NetBSD 1.5.3_ALPHA (MLB) #6: Fri Nov 16 17:55:25 EST 2001 i386
Architecture: i386
Machine: i386

NIS is having trouble with some (but not all) accounts, whereby using rlogin,
for example, fails to successfully authenticate at first, requiring the user
to enter a password regardless of the presence of a correct entry in .rhosts.

Here's the relevant excerpt from a destination system:

Nov 21 12:47:38 targetsystem inetd[16773]: connection from originatingsystem, service login (tcp)
Nov 21 12:47:38 targetsystem rlogind[16773]: someuser@originatingsystem as someuser: iruserok failed

The NIS server in all cases is 1.5.3_ALPHA, and destination systems have been
1.5.2, -current, and 1.5.3_ALPHA systems.

Note that while rlogin seems to fall back on a password exchange with
the user which then works, things like "rsh target foo" will just fail
out of hand every time for non-working accounts. Also note that what
distinguishes working accounts from non-working accounts is not yet
known. Being logged in to the destination box already seems not to make
a difference.

Note that "ypcat passwd" returns everything it should consistently.


Use NIS.


No idea what's wrong, yet.
