I am new to Fedora DS and have installed 1.0.4 onto a Fedora Core 6
(+ enhancements) build. I have built the install using the dsbuild

system using the 'admin' user and the "CN=Directory Manager"
identity. I have SSL working and now want to use our Kerberos
environment to provide SSO to the server.
Our Kerberos environment is based on an AD KDC and is supporting
other application successfully. We have created the 'ldap/...'
service principal and imported it into the system keytab.
First test with ldapsearch using GSSAPI fails with permission denied
from the GSSAPI function. So I thought I would try the mapping
facility as documented in the administration manual and set up to map
the Kerberos identity to the correct search DN for the AD. As we only
have the one Domain/Forest I set up a simple map that takes any name
and maps to this DN. I then set up a referral inside the DS to point
to the AD controllers in the hope that this would activate the
necessary logic. No joy.
Looking in the code for 'saslbind.c' it looks like the code only
allows for locally registered users. If I am reading this right does
this mean my next step is to remove the referral and add a replica
for the AD into my DS using the procedure outlined in the
Administration Guide section "Windows Sync".
Yes. I believe you have to have an entry associated with the
principal in Fedora DS. So yes, you will have to sync your user
information from AD to Fedora DS.
In doing this will I have then enabled GSSAPI/Kerberos authentication
or will I still be missing something? If I do this will I be causing
problems in the future with other parts of the AD as I want to get
referrals when the data is not held in the DS?
Well, it depends. What are you using Fedora DS for? Are you just
using it as an authentication gateway to AD? If so, then you could
probably just use something like pam_winbindd and skip Fedora DS
altogether.
(Given that I will be syncing users (and groups?) only). I can use OU
trees for this and tie the referrals there of course but then I will
need to sync the entire CN=Users tree.
I understand that I will need to create a separate DIT (root) for the
AD data to ensure that I can sync to multiple domains in the future,
is this correct?
I'm not really sure. Can you explain more about your topology and how
you want to use Fedora DS?
Any advice or even a description of the set of steps that will make
this dance work would be much appreciated.

Richard,
I am implementing the Fedora DS to provide data from other domains than
my AD. So I have other roots in the Directory Store already. I also will
be storing additional information for users in the DS to support RADIUS
and other applications. However our primary authentication store is on
Windows 2003 using the KDC. I have users who have Kerberos tickets
granted and can do GSSAPI exchanges with the AD to retrieve LDAP
results. The DS has a map which I believe should take a Kerberos/GSSAPI
identity and map it to a LDAP lookup. I have arranged for users to be
synchronised using the Windows Sync and am trying to match on
uid=<samAccountName>,OU=People,DC=example,DC=com for the user.
From the debug logs I am not sure that the DS is doing the GSSAPI look
or executing the maps but I get permission denied response with
'ldap_sasl_interactive_bind_s: Invalid credentials (49)' as the primary
message.
I am not sure where to look next unless what I need to do is to add some
acl's for the users currently I just want to get LDAPSEARCH working with
Kerberos.
Howard.
