Cant authenticate to LDAP domain with Redhat9


Hi,

I'm new to ldap and fairly new to linux as well so bare with me.....


I've recently installed Red Hat 9 over Gentoo due to some commerical software support. My problem is that I can not get Red Hat to authenticate to the ldap domain.
Here is the current ldap software I have installed:

[root@hostname root]# rpm -qa | grep ldap
openldap-2.0.27-8
openldap-clients-2.0.27-8
nss_ldap-202-5
openldap-devel-2.0.27-8
openldap-servers-2.0.27-8
php-ldap-4.2.2-17.2

Here is current openssl:
[root@hostname root]# rpm -qa | grep openssl
openssl-0.9.7a-20.2
openssl-perl-0.9.7a-20.2
openssl096b-0.9.6b-15
openssl-devel-0.9.7a-20.2
openssl096-0.9.6-25.9

I also have autofs installed and running.
I have copied the exact files for /etc/ldap.conf, /etc/nsswitch.conf, /etc/pam.d/system_auth, and /etc/ssl/certs/eeca.pem, and /etc/autofs/auto.master
which work on other linux computers (Mainly Gentoo).
I also copied ldap.conf into /etc/openldap/ldap.conf and copied /etc/autofs/auto.master to /etc/auto.master.

So my config files must be correct if they work on other computers...
Leaving me to believe that must be extra config files on Redhat that I must setup.
I took out the hostname and domain names in the following test.

Test:
[root@"hostname" root]# ssh -ltestuser "hostname"
testuser@"hostname's" password:
Permission denied, please try again.

Log file:
sshd(pam_unix)[14275]: check pass; user unknown
sshd(pam_unix)[14275]: authentication failure; logname= uid=0 euid=0 tty=NODEVssh ruser= rhost="hostname"."**"."***".edu
sshd(pam_unix)[14275]: check pass; user unknown
sshd(pam_unix)[14275]: 1 more authentication failure; logname= uid=0 euid=0 tty=NODEVssh ruser= rhost="hostname"."**"."***".edu



Any Ideas on how to resolve this issue? Thanks.

Unhappy Help

Either I always pick the hard questions to ask or there so easy no one bothers to answer....

Anyways I have been working on this problem for days and any info will be most appreciated.

Also here is some more info on the problem.
When I run ldapsearch i get this...

[root@blochEE root]# ldapsearch -x -b "dc=ee,dc=ucr,dc=edu" uid=grad-adm
version: 2

#
# filter: uid=grad-adm
# requesting: ALL
#

# grad-adm, People, ee, ucr, edu
dn: uid=grad-adm,ou=People,dc=ee,dc=ucr,dc=edu
uid: grad-adm
cn: Graduate Affairs
sn: Affairs
mail: grad-adm@ee.ucr.edu
labeledURI: http://www.ee.ucr.edu/~grad-adm
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: top
objectClass: shadowAccount
loginShell: /bin/bash
uidNumber: 30501
gidNumber: 402
homeDirectory: /home/eemisc/grad-adm
gecos: Graduate Affairs

# search result
search: 2
result: 0 Success

# numResponses: 2
# numEntries: 1
[root@blochEE root]#


And when I get this running getent:
[root@blochEE root]# getent passwd grad-adm
grad-adm:x:30501:402:Graduate Affairs:/home/eemisc/grad-adm:/bin/bash
[root@blochEE root]#

From my understandings it looks like the client can communicate ok with the server, so I am at a loss as to why I can not login using users on the ldap server?


If you need any more info. please let me know and I'll be happy to provide it.
Any responses will be most appreciated.
Thank you.
