Questions on openldap and kerberos....

[John Tobin]

Dear Kerveros,

Please inform me if this is inappropriate for the kerberos forum,
I understand this is probably a user bug...
I have looked under a number of different pieces of documentation,
I am probably looking in the wrong places.
Assistance is requested from those who may be able to provide guidance.
I may even try to document my efforts if that will make it reasonable for
rookies [like me!]
Sorry for the length.

I have installed kerberos 1.10.2 from suse 12.2.
I have installed openldap 2.22.2 from suse 12.2 also.
I am assuming that there are a few people who have this working.

I have followed the Chapter 6 of the suse admin guide:³Network
authentication with Kerberos² from
http://doc.opensuse.org/documentation/html/opensuse121.....:
And followed the directions from 6.4.11. Using Ldap and Kerberos
This set of directions creates the  principal:
Ldap/ldap.dark1.net,
And tells me to add this entry to the keytab:
kadmin: ktadd ldap/ldap.dark1.net

Then goes over options for making the keytab readable by ldap [group], which
I did.

The suse documentation has been my guide to get kerberos working, and that
has been successful.

I can login with a kerberos id using ssh, as well as login with a standard
id, so I assume kerberos is working.

A standard ldapsearch ­x ­b for a known id works [the ­x allows ldapsearch
to work without sasl ­ so without kerberos],
A [I assume kerberos] ldapsearch ­b Œdc=dark1,dc=net¹... Does not, see the
errors in the case doc.

Below I have a quick outline of the case :
current status of tasks for kerberos and ldap,
the 2 queries,
Kdc.conf
krb5.conf
Ldap.conf [client]

Assistance would be appreciated.

Sincerely, 
tob
