|
||
|
|
authenticating to the iSeries using Kerberos. To install and configure iSeries for
|
||
|
|
Kerberos, see the Single signon topic, in the Security topic collection.</p>
|
||
|
|
<p>To
|
||
|
|
install and configure Linux for Kerberos, see one of the many <span class="q">"How To's"</span> available
|
||
|
|
on the Internet. For example: <a href="http://www.linux.com/howtos/Kerberos-Infrastructure-HOWTO/client-configure.shtml" target="_blank">www.linux.com/howtos/Kerberos-Infrastructure-HOWTO/client-configure.shtml</a></p>
|

|
<div class="note"><span class="notetitle">Note:</span> Most Linux distributions
|
||
|
|
have at least one (Heimdal and MIT) version of Kerberos 5 included with them.
|
||
|
|
However, some distributions neglect to create a symbolic link for the Kerberos
|
||
|
|
shared library (Heimdal /usr/lib/libgssapi.so or MIT /usr/lib/libgssapi_krb5.so). iSeries Access
|
||
|
|
for Linux dynamically
|
||
|
|
loads the Kerberos shared library by that name and if a symbolic link to that
|
||
|
|
name is not available, you get the following error: CWBSY1015 - Kerberos not
|
||
|
|
available on this version of the operating system.</div>
|
||
|
|
<p>To use Kerberos
|
||
|
|
with iSeries Access
|
||
|
|
for Linux,
|
||
|
|
you must first authenticate to your Kerberos domain using the <samp class="codeph">kinit</samp> command
|
||
|
|
or by setting up your initial Linux login to authenticate with the pluggable
|
||
|
|
authentication module (PAM) Kerberos plugin. After successful authentication,
|
||
|
|
you should be able to do a <samp class="codeph">klist -f</samp> to see the status of
|
||
|
|
your Kerberos tickets.</p>
|
||
|
|
<p>For any iSeries Access function, you can use <samp class="codeph">*kerberos</samp> in
|
||
|
|
place of the iSeries user
|
||
|
|
profile to use your Kerberos tickets. Any password will be ignored in this
|
||
|
|
case. For example: <samp class="codeph">/opt/ibm/iSeriesAccess/bin/rmtcmd CRTLIB Test /system:iSeriesSystemName
|
||
|
|
/user:*kerberos</samp>.</p>
|
||
|
|
<p>The Kerberos principle name will be based
|
||
|
|
upon the fully qualified TCP/IP name received from the reverse lookup of the
|
||
|
|
TCP/IP address. If you use a hosts file to resolve TCP/IP addresses, be sure
|
||
|
|
to include the fully qualified TCP/IP system name. For example: <samp class="codeph">1.2.3.4
|
||
|
|
MyiSseries.MyDomain.com MyiSeries</samp>.</p>
