broken NIS clients
Hello friends,
I recently ran an upgrade on my system which is debian sid(most of it) during
the upgrade I noticed that libc6 version is also being upgraded .
After the upgrade I noticed that my machine rejects any NIS login. It allows
login through local accounts though.
I have attched two sections of auth.log file
here user shashank is a NIS user. If I do ypcat passwd or passwd.byname I get
the entire passwd db from NIS sever. also ypwhich points to correct ypserver.
We have only one NIS server on the network and no NIS slaves running.
My experience with NIS is not very vast.
I went through google but those docs did not help me much.
version of libc6 running on the system is 2.3.2-3
version of nis on system is 3.9-6.3
