Re: [Fedora-directory-users] Forgive the misunderstandings of a "newb"



I am running Fedora Core 5 and have (as far as I can understand) all required modules, etc. installed, I have checked the ldap.conf file and it is pointing to our LDAP server, I have checked the nsswitch.conf file and it appears to be configured correctly. But after having deleted the user from the local machine, I now cannot login because of authentication failure.
System-config-authenticatin in pam.d contains this:

#%PAM-1.0
auth            include         config-util
account         include         config-util
session         include         config-util


So, back to the drawing board and more searching on the web. It seems as if most of these how-to's are geared toward people what have a working understanding of how all of this integrates into LDAP. An assumption that I wouldn't necessarily make, especially in light of the fact that if you come from a Windoze server environment, AD is used which doesn't have all of these configuration issues (you just get a whole new set of issues).

Thanks Nathan, but where did I miss that in the how-to?
It appears to be missing from the how-to (some of the how-to's do make reference to nss_ldap being required though).

I thought I was smart until I dove into LDAP. I am the sole
part-time IT
Manager for a charter school (240 students, 20 staff, 60 computers)
and
am migrating away from a Windows server environment to Linux. The
only
services that are being provided by a Windows server now are AD,
file
and print sharing services. Since we are turning about 15 of our
student
computers into Linux stations, I decided on a "simpler" method of
managing authentication, login etc. and chose Fedora Directory
Server
(after having beat my head against the wall with strictly OpenLDAP
for a
month). I have successfully set up FDS and entered all students and
staff. I have decided not to sync against our AD server because we
are
changing the student login method, the old format was locker number
for
user name and then a password. I have decided to use the first.last
name
for user name and then a password.

I am trying to set up posix authentication and Samba and am having
difficulties with both, technical on the former and understanding on
the
latter. First posix, I have followed the how to on the FDS Wiki, but
there seems to be some steps missing. I have gotten an authenticated
student logon, but only after having created an account on the local
machine with the same UID. I made sure that the password was
different
in FDS than when I created the user on the local machine and I am
able
to login to using either password which would indicate to me that I
am
successfully authenticating to FDS. However I don't particularly
care to
have to add 240 students on all 15 computers to make this work, not
to
mention all of the "home" directories that will be mounted from the
NFS
server. So the questions is, what steps am I missing here?
It sounds like you need to configure nss_ldap.  Assuming you have
nss_ldap installed on your client systems, you should be able to add
"ldap" as a service for looking up users and groups in your
/etc/nsswitch.conf file.

-NGK
Samba. As I understand it, Windows will only authenticate against an
NT
or "NT like (aka. Samba)" server, which means as far as I can tell
that
either I have Samba sync against FDS or I use pGina on the Windows
side
to authenticate directly against LDAP or scrap LDAP all together and
just use an NIS server (don't think this is a good idea, but it is a
possiblity). Of course trying to assess the pros and cons of either
has
been somewhat difficult at best. Also the FDS Samba how-to doesn't
cover
computer management which Samba is going to have to deal with as
well.
Before someone replies with a "RTFM", I have read the Install Guide
as
well as the Red Hat Directory Server documentation and I am
currently
half-way through the book "Understanding and Deploying LDAP
Directory
Services", so I have a reasonable understanding of how to get into
trouble. Of course none of these provide in-depth (nor should they)
information as to how to integrate with other services. I have spent
a
month reading, tinkering etc., and I am not asking anyone else to do
my
work for me, but I have seem to hit a wall and need a couple of
"breadcrumbs" to get me back on the trail. Thank you for your
patience
and understanding.
