NIS and autofs trouble with FC5

Hi,

We have been successfully using NIS with autofs for several years.
However, recently when I upgraded one of our servers, and my desktop
client machine to use Fedora Code 5, things started to fall apart.
We have an "auto.home" file that is provided by our NIS server. If
the NIS server is running on our old server (running EL 1), everything
works great from all client machines. However, if the FC5 server is
handling NIS, when I attempt to access an autofs directory from my FC5
client, ie: /home/steve, I get the following error reported to the log
on my client machine:

Nov 8 08:55:59 steve-pc3 automount[14242]: >> mount: special device
/mnt/users/software/steve does not exist
Nov 8 08:55:59 steve-pc3 automount[14242]: failed to mount /home/steve

It appears that the server "marge:" is being stripped from the mount
device.

The line in auto.home is the same as it has always been:
steve marge:/mnt/users/software/steve

ypcat auto.home displayes the correct auto.home file.

Interestingly, if I attempt to access /home/steve from another client,
not running FC5, for instance an old Solaris machine, everything works
fine.

Anyone have any ideas?

Thanks in advance,

-Steve

So on the client you get
# ypcat -k auto.master
/home auto.home

# ypcat -k auto.home
steve marge:/mnt/users/software/steve
(there is only one string of white spaces in there)

# nslookup marge
works

... a manual mount works? (Cut/Paste it to make sure it is spelled the same)
mkdir /tmp/steve
mount marge:/mnt/users/software/steve /tmp/steve

just to be sure automount is up top date
# service autofs reload
# ps -ef | grep auto.home
automount --timeout=60 /home yp auto.home
.... actually I dont have that running, it should be about that.

# cd /home/steve
still fails... same error?

Maybe be really sure?
# ypcat -k auto.home | od -c

but it works on non FC5 machines... I don't know.

Hi Mike,

I found the problem. A regular mount was also failing when I was
pointed to the new NIS server. I tried to determine which NIS maps
that mount depended upon; then, I noticed that I neglected to copy our
"group" file over to the new NIS server! Once I did this, everything
began to work properly.

Thanks for your help.

-Steve
