Description Maarten van Gelder 2003-01-28 04:21:48 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; T312461)

Description of problem:
We have a NIS server running with NIS domain name KVI (upper case).
During the installation of RedHat 8.0 on a NIS client I typed the NIS domain 
name (KVI) in capitals.
After installation in the reboot the NIS server lookup failed.

The information in /etc/yp.conf and also from 'nisdomainname' showed the domain 
name as 'kvi'. Whereas the file /etc/sysconfig/network showed 'KVI'.

After using 'authconfig' (without changing anything) the domain name was set to 
upper case and the NIS server was found.

But after a reboot the same problem arouse: NIS server lookup failed, because 
of the lower/upper case mismatch.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Just reboot

Actual Results:  see description field

Expected Results:  Keep the original upper/lower case NIS domain name.

Additional info:

Why does the RH8.0 'system' convert the NIS domain name to lower case during 
the boot (but not everywhere)?
The NIS domain name is case sensitive (see the RFC)!

Reassigning to a more appropriate component, this issue has nothing to do with RHN.
Comment 2 Maarten van Gelder 2003-02-19 08:00:45 EST
While browsing through the system files I found a dhclient lease file that 
showed the NIS domain name in lower case. Indeed our DHCP server returned that 
option. After changing the DHCP configuration NIS domain option to upper case 
the problem vanished.

I suppose RedHat 8.0 takes the NIS domain name from DHCP whereas the previous 
versions we use (6.2 and 7.1) take the name typed in during installation.

RedHat 8.0 installation still asks for the NIS domain although DHCP is used.
So I didn't find out the changes directly ...
