Hello,

Please this is very urgent.Some one please help me!

I have configured SAMBA PDC with LDAP just now. I don't know much about LDAP.
Finally i have created user using smbldap-useradd

I restarted the samba service and ldap service.Everything was fine.

When i try to login to the ldap server using ssh, i am getting following error:
"Permission denied, please try again."

The ldap server log showed following error:

Sep 2 02:12:34 twilight sshd(pam_unix)[19289]: check pass; user unknown
Sep 2 02:12:34 twilight sshd(pam_unix)[19289]: authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.100.82
Sep 2 02:12:34 twilight sshd[19289]: pam_ldap: ldap_search_s No such object


I am not able to debug this problem, can someone help me out.

Note: The howto that i refered had instructed me to install pam_ldap and nss_ldap. But i have not found pam_ldap package for FC4. Is this the problem?

Below are my Configuration files:

BTW, Distribution is Fedora Core 4
Samba 3.0.23a-1
openldap-2.2.29-1.FC4
nss_ldap-234-4
openldap-servers-2.2.29-1.FC4
smbldap-tools-0.9.2-2.fc4
openldap-devel-2.2.29-1.FC4


Thanks in advance
Gokul

hello all,

some one please respond me! Now i can authenticate linux abd windows client using ldap+sambaPDC. But i could not mount my home directory.

when i try to login to ldap client using ssh i got this ERROR:

#ssh test@192.168.100.4
test@192.168.100.4's password:

I have a how-to on my website http://www.opensourcehowto.org for setting up samba as a primary domain controller (PDC)

OpenLDAP LAM Samba as PDC
http://www.opensourcehowto.org/how-t...ba-as-pdc.html

and if you feeling a little bit more adventurous later on you could try getting into the policies with samba

Samba Primary Domain Controller with Group Policies
