NIS Client 's /etc/passwd
|
|
|
Hi ,
I've set up an NIS Server on a Linux machine (Red hat) and verified
according to the Linux
NIS How -to : http://www.tldp.org/HOWTO/NIS-HOWTO/index.html
I try to login to the client with my NIS username but I get "unknown
user"
a look at the system log /var/log/messages gives me "unknown user". I
checked up some
FAQs but not able to find an answer.
I guess I am missign something basic to do with the local /etc/passwd
file.
Can someone throw some light?
Thanks in advance!! |

Check your /etc/nsswitch.conf file.

1) Make sure your nsswitch.conf has the following lines:
passwd: files nis
shadow: files nis
group: files nis
or
passwd: compat
group: compat
Otherwise, the OS is just looking it up on local files.
2) Make sure you have nscd installed. Made that mistake recently.
rpm -qa | grep nscd
3) Make sure you can bind correctly -- ypmatch -k <username> passwd
should return you your entry. May need to be root to do this.

In which case you have to insert the BSD style "separators" into the
passwd and group files.

Why? Nscd and NIS interact very badly. You make a change to a map and nscd
has cached the old value and it doesn't take effect. IME it is not a good
idea to run it in a NIS environment (or indeed at all unless you have some
serious performance problems with your name services). I do not have nscd
installed on this (Debian) NIS client.

You don't need to be root.
