When ever I have an issue with our LDAP server (which I was able to fix) we see the following errors in /var/log/messages and it causes problems with our services running on that box, e.g. httpd, nrpe, xinetd, etc. Aug 8 17:44:42 hostname httpd: nss_ldap: failed to bind to LDAP server ldap://serveraddress/: Can't contact LDAP server Aug 8 17:44:42 hostname httpd: nss_ldap: reconnecting to LDAP server (sleeping 64 seconds)... I am only wanting to authenticate SSH and Sudo and not services like httpd, nrpe, xinetd etc.
View 2 Replies View RelatedI'm trying to set up a Samba share that's available over the network to a group of users in our institution. Our infrastructure is based on Novell Netware (slowly migrating to OES), and thus our authentication is managed by eDirectory. All our other shares are managed by Netware, but this one lives on a standalone Ubuntu server.
I've succeeded in setting up the share, and users can access it without a problem. The trouble is that currently it only works by treating all users as guest users and giving them the same privileges over the share. Is it possible to get Samba to authenticate users against eDirectory via LDAP? Would I have to get Ubuntu to authenticate against eDirectory, then Samba against Ubuntu, or can Samba do it directly? I've not really worked with LDAP before so I'm unsure where to start.
How to authenticate Samba server with another LDAP Server.
- I would like to set up samba server(CentOS5 samba version 3.0.33)for sharing directory. WindowXP client will can access to samba if username and password match with username and password of another existing LDAP server.
- I only know URL and DN of LDAP server and can not modify anything on LDAP Server.
- Can I config at samba server for requirement above.
How can I make the user in remote LDAP server to be used to authenticate Local Linux server ?

I had 11.1 for some time, was working fine. decided to upgrade... long story short - did a fresh install with livecd of the 11.2. I use ldap server for authentication, its on the lan. configuration during install goes through fine. fetch dn, etc... then after the bootup - authentication error for any user except root. At the same time automounter works fine, ldap requests are going through for hosts (my local hostnames are also on this ldap server), I can edit users through YAST when logged on this box, but alas! even for "su - user" I get "incorrect password", whereas if I am root, then "su - user" gets me logged in as user. password does not go through!

I have a query regarding login to roundcube via dovecot ldap. I have installed and set up the openldap on Ubuntu Server 11.04 with the help of the following article [URL]. I have also installed Postfix, Dovecot, Dovecot-ldap and roundcube as the mail client. Then, I went on to test if I can login through roundcube. I received "login failed". I'm sure the dovecot is running fine as well as Postfix and openLDAP server. All I can find from the log was "auth(default) LDAP: Can't connect to server: localhost".
View 1 Replies View RelatedI manage to get RHEL Authenticate to Active Directory using LDAP and Kerberos. When a user authenticate to the Unix, the Unix system will check (using Kerberos) to the AD. However I just found out that when the RHEL (LDAP) did the authentication to the AD (to ensure that the RHEL has the right permission to query the LDAP database), it uses simple bind which send the username/password unencrypted over the network.
1) Can We use Kerberos as well? for the initial authentication described above?
2) If Not possible, is there a way to encrypt the username/password in the storage (ldap.conf -because it's world readble)? I know that for tranmission I can use SSL.

we have a weird problem with our opensuse 11.2 server installation.
We want to set up a LDAP Server using the Yast-LDAP Server configuriation tool.
This indeed already worked weeks ago until....this week.
Maybe some updates??!
I do not know what happend exactly. The server just does not want to start again and throws following error:
Starting ldap-serverstartproc: exit status of parent of /usr/lib/openldap/slapd: 1 failed
This happend after a little check of the configuration, but without a change, with Yast. Google delivered only "reinstall your box"-answers.
So.. i did that. And now the "mystical" part: The SAME ERROR occurs with a fresh vanilla system with a brand new and simple configuration (certificats, database, pw...the first Yast config dialog...). I did not change the way i set it up.
I remember, when i did this the first time with 11.2 on that machine, when no problems occured...everything was running out of the box (except the "use commen server certificate" option...).
So far, I've been able to get my Box (Centos 5.3) authenticate users through LDAP. My next plan was to automount their home directory from our NAS device.But I'm struggling getting autofs talking to the LDAP Server.My Config Files:

i have configured ldapserver on rhel4 for creating address book
following are configuration files on ldap server

include /etc/openldap/schema/core.schema
include /etc/openldap/schema/cosine.schema
include /etc/openldap/schema/inetorgperson.schema
include /etc/openldap/schema/nis.schema
i am able to import this ldif file into database.also when i perform the ldapsearch on this server with command"ldapsearch �x �W �D �cn=manager, dc=example, dc =com� �b �dc=example, dc=com�" i get correct output.
but when i am trying to search from another client machine, i am getting "error ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)"
also when i configured address book on mozilla on server., it is working fine.but not working on another machine.is any configuration is missing on client machine.both ldap server and client are configured on rhel4es without any firewall or selinux.
i have successful secure ldap replication but i could not make ldap client to direct its authentication to slave ldap
here is my config file on ldap client (i am not sure if it is the right place though)

ip : 192.168.1.185 is slave ldap

I am using RackMonkey to map out my lab. Unfortunately, due to RM limitations, every user who accesses the site has write access UNLESS they are logged in as a user named "guest". I currently have Apache allowing only the users (sysadmins) in an LDAP group access to RM, but I would like to allow read-only access for other users as well.I found mod_authn_anon, but I am having trouble combining the two authentication methods. I am using Apache 2.2.18 (compiled myself) on SLES 11.1.
This is the common part:
Code:
AuthType Basic
AuthBasicProvider ldap anon
Order allow,deny
Allow from all
This part by itself works for the LDAP authentication:
Code:
AuthName "System Admins"
AuthLDAPURL "ldaps://example.com/ou=ldap,o=example.com?mail" SSL
Require ldap-group cn=SysAdmins,ou=memberlist,ou=groups,o=example.com
This part works by itself for guest access:
Code:
Anonymous guest
Anonymous_VerifyEmail Off
Anonymous_MustGiveEmail Off
Anonymous_LogEmail on
Require valid-user
But if I have both of the previous blocks enabled at once, then guest access does not work. If I throw in a "Satisfy any", then I am not prompted for a username at all. How can I allow access to this LDAP group and to a user named "guest", but not allow all valid LDAP users to log in?
I'm trying to set up a Linux server and I am new to this. I have gone through most of the configuration using SAMBA 3.0 and when I populate the ldap directory all I get this error before the password request:
Then when I perform an ldapsearch to see if the directory is populated I get this message:
I'm positive all my .conf files are done right.
I'm checking with a sniffer and there's activity going on between the client and the LDAP server... as a matter of fact, the sniffer shows that the search is producing one ldap item, however, php says it can't contact the ldap server (after it has bound and everything):
The script is working beautifully on another host with debian.
In the past I found some great help on this forum, so here goes. Bare with me because it's a long story. I'll try to be as complete as possible. I've installed and configured OpenLdap on a virtual machine with ip 192.168.39.134. I've added 2 users via LAM. In the ou WikiUsers and the domain is wiki.local.
I've then created another host with ip 192.168.39.133 with mediawiki installed on it. Then I added the extension LDAPAuthenthication. In the LdapAuthentication file I added this code (only the last paragraph is mine, I added the others to show it's location in the script):
Quote:
$path = array( $IP, "$IP/includes", "$IP/languages" );
set_include_path( implode( PATH_SEPARATOR, $path ) . PATH_SEPARATOR . get_include_path() );
[code]...
I know I'm close because I can't register any new users or accounts on the mediawiki site. Although I could before I added the LDAP service. This is indeed all just to test and get to know how LDAP works. That's why it's all virtual in VMWare. I did not really configure anything on the LDAP, i just installed it and chose a domain (wiki.local).
I installed openLdap on a debian machine for some testing. I followed the instructions here. [URL] Now when I try to do any thing it prompt me for password Which I do remember correctly. However it comes back with error.
Code:
~# ldapsearch cn=admin
SASL/DIGEST-MD5 authentication started
Please enter your password:
ldap_sasl_interactive_bind_s: Invalid credentials (49)
can anyone tell me what is the difference between these two files of LDAP client /etc/ldap.conf and /etc/ldap/ldap.conf and for what purposes these two files gives services. Is it necessary to have these two files at a time ?
I use these files to install LDAP client to authenticate with our LDAP server by creating a symbolic link of /etc/ldap.conf to /etc/ldap/ldap.conf.
I had a machine that is using ldap, but need to remove it completely.I edited the /etc/nsswitch.conf and removed all references of ldapand renamed /etc/ldap.conf to /etc/ldap.conf.bakI can log in as root, but cannot log in as any user in /etc/passwdIn the /var/log it shows pam_ldap: missing file "/etc/ldap.conf"I am guessing I am missing something else?I never set this machine up for ldap, was here when i got here, so not sure of steps to even put ldap on.

What do i need to do precisely. I have kerberos & Samba installed. Do i need both of them or can I just go ahead and set up one.
We're still using an NT Domain Server, and Samba is already configured properly. But the problem is if the shared folder is configured in samba to be accessed by group and not the domain username, authentication fails even if the user is member of the group.
Example#1: (authentication successful)
[sharedfolder]
valid users = domain+username
Example#2:
[sharedfolder] (authentication fails)
valid users = @domaingroup
Samba version is samba-3.0.33
I don't know what happened but sendmail suddenly stopped authenticate my users who tries to send mail.
I use slackware 13.0 and sendmail for SMTP with ssl and plain authentication. Imapd works fine.
There is nothing in logs just that the client did not issue MAIL/EXPN/VRFY/ETRN during connection.
