The libraries for 4.5.19 are broken. NIS won't work with it.
-
If you upgrade the libraries from 4.5.19 to 4.5.24 then the su
command breaks. You need to get the su command from the slackware
1.2.0 distribution. Incidentally that's where you can get the
updated libraries.
-
When a NIS server goes down and comes up again ypbind starts
complaining with messages like:
yp_match: clnt_call:
RPC: Unable to receive; errno = Connection refused
|
and logins are refused for those who are registered in the NIS
database. Try to login as root and kill ypbind and start it up
again. An update to ypbind 3.3 or higher should also help.
-
After upgrading the libc to a version greater then 5.4.20, the
YP tools will not work any longer. You need yp-tools 1.2 or later
for libc >= 5.4.21 and glibc 2.x. For earlier libc version you
need yp-clients 2.2. yp-tools 2.x should work for all
libraries.
-
In libc 5.4.21 - 5.4.35 yp_maplist is broken, you need 5.4.36 or
later, or some YP programs like ypwhich will segfault.
-
libc 5 with traditional NIS doesn't support shadow passwords
over NIS. You need libc5 + NYS or glibc 2.x.
-
ypcat shadow doesn't show the shadow map. This is correct, the
name of the shadow map is shadow.byname, not shadow.
-
Solaris doesn't use always privileged ports. So don't use
password mangling if you have a Solaris client.
