Hello,
I have a strange problem with a redhat 4.0 (all patches installed
following the instructions).
My non standard setup is:
- two yp servers (Sun with SunOS, sorry :-)) with C2 enabled;
- some linux boxes with shadow passwords and running various flavors
of nis: old slackware, debian, redhat 3.0.3 (these with the shadow
rpms and NYS) and a redhat 4.0.
On all of them my solution to make shadow and nis work together is:
* a passwd file with only the standard entries and the +::::::: when
needed (not for NYS);
* a complete shadow file built starting from the passwd.adjunct.byname
map sources, redistributed via rdist on all the linux machines.
On all the linux machine I don't have problems, including redhat
3.0.3. With 4.0 I can log in via rsh or rlogin, if I have a .rhosts
file set in the right way. But if I connect via telnet or if I try to
log from the console, the authentication fails.
If I put the entry for my account in /etc/passwd, all works in the
right way.
Ah, another thing: I wrote that I have to configure the .rhosts file
in the right way, but it isn't correct: I have to put the yp server
name, and not the name of the host from which I connect to the linux
machine. This isn't a problem for rlogin, but it's a big problem if
my printer isn't attached to the ypserver. I remember that I found
the same problem some year ago (libc 4.6.20 or so, with NYS compiled
in), but I didn't find it in redhat 3.0.3 and libc 5.2.18 so I
thought it was corrected.
Any hints? Tomorrow I'll try with compat in /etc/nsswitch.conf and
ypbind to see if the behaviour is different.
Cheers,
andrea
