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.
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...).
Just installed openldap server on a VM CentOS called 'ldapsrv', it works fine, ldapsearch returns all ldap information.
Installed openldap client on another VM CentOS called 'ldapclient1', configured it with most basic configuration, no ssl/tls etc. but ldapsearch returns error:
ldapsrv is pingable:

i have configured ldapserver on rhel4 for creating address book
following are configuration files on ldap server
/etc/openldap/slapd.conf
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.
why i can't login on the ldap-client via ldap, so here is a short description of my machines (i use openvz virtualising)I have on the HN (Debian Lenny) 2 VE's, which are in the same subnet (192.168.1.0/24)The first VE (Hostname: ldap1, IP: 192.168.1.91) is the ldap-server, which is so configured, that i can manage the server via phpldapadmin.The second VE (Hostname: ftp1, IP: 192.168.1.31) is the ldap-client, there should run a sftp-server in the future and the sftp-server(ssh-server) should use ldap-usernames to login. on the ftp1, i get with this command getent passwd the users configured on the ldap-server, but with the command id USERNAME the result is, that the user doesn't exist. (USERNAME is this name, i get returned by getent) and if i try to login via ssh, i get permission denied. and because the machines are openvz-virtual-machines, so i can't login on them like on a normal system, but a su USERNAME doesn't work too, because the user is not known on the system.
my installation:
i don't think, that the ldap-server is the problem, because the phpldapadmin and getent on ftp1 are working perfectly, but if you want, i can post the config here too. the VE ftp1 was configured with the following how-to: [URL] and pam is configured like in the chapter "PAM setup with pam_ldap" on [URL]
I took to yast to install ldap. I creating the CA cert, server key and server cert and specified them during the yast ldap server dialogs.
The firewall is open for ldap.
I also went through yast's ldap client ... though I didn't exactly see to anything (presuably it wrote up a configuration file somewhere).
However when trying use the basic ldap tools, like ldapwhoami. Well it doesn't connect and gives me the above error. Of coure the ldap db is unpopulated as yet, so it probably is not able to say who am at all. But ldapadd doesn't work either.
It seems to point to my SSL usage not being correct .. so I'm trying to double check that now.
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 : 192.168.1.183 is master ldap
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 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.
I installed CentOS 5.2 and then run yum update. I configured this server as LDAP/Samba primary domain controller. LDAP seems to be OK and for testing I am able to create users with:smbldap-tools useradd -am usernameI can ssh into the server as root and also as a Linux user which was locally created in the server. But ssh into the server as LDAP user fails (from a Fedora 11 machine) with "Permission denied, please try again", prompting again for password.Some data:
# rpm -qa | grep ldap
python-ldap-2.2.0-2.1
php-ldap-5.1.6-23.2.el5_3

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.
View 2 Replies View RelatedIn 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 have set it up, but I'm not sure whether the admin username and password are set correctly. How do I confirm? Also, if someone has any links explaining the format of an LDIF file.

View 18 Replies View RelatedI am aware that there is a qmail-ldap package to have ldap back end for qmail. But I need only user authentication for qmail through ldap (not the backend; i.e still keeping Mysql as the database). I am pretty new to mail server configuration.

I've setup an Ubuntu 10.10 LDAP Client to authenticate off my LDAP server. I've install the following: sudo apt-get install libpam-ldap libnss-ldap nss-updatedb libnss-db nscd ldap-utils pam_ccreds Here's my /etc/nsswitch.conf: passwd: files ldap [NOTFOUND=return] db group: files ldap [NOTFOUND=return] db

I've compiled openssh-5.4p1 on RHEL 4.8 with Openssl 0.9.8m + pam It works perfect without pam (pam-0.77-66), both with password and public key auth. Whith pam enabled and LDAP (openldap-2.4.21, from scratch) something strange happens: system users: I can do ssh with both password and public key LDAP users: public key works for remote users, still I cannot do ssh with just password. I'm trying a custom PAM configuration, because the default one (even with authconfig + LDAP ) blocks ssh even with system users.
My pam SSHD configuration is:
#%PAM-1.0
auth required pam_env.so
auth sufficient pam_unix.so likeauth nullok
auth sufficient pam_ldap.so use_first_pass

My LDAP users are ok: i can do "su - " remote LDAP (so that nss_ldap is OK), also getent passwd and getent group is ok.
How can I verify the following service configuration files/setup are ok with?(in RedHat)
httpd
sendmail
ldap
DHCP
DNS
SQUID
For example, I can use "testparm" to verify the my samba configuration . I want a similar kind of testing option for the above mentioned options.
I am using centos 5.5 x85_64 2.6.18-194.3.1.el5 The server is hanging at start up due to the follwoing error

udevd[746] failed to bind to LDAP ser er ldap://192.168.0.100 cant contact ldap
It fails and then tries again, and again, each time increasing the sleep time. This is happening before network sercvices are started so ther is no way it can connect to ldap. anyone know a way to fix this problem?
I have LDAP authentication working via SSSD using authconfig-tui and a few minor modifications to sssd.conf (ie: max_id etc). The problem I am having is it would appear /etc/ldap.conf is being ignored and/or setups that work perfectly on RHEL5, F11 and F12 no longer work on F13. Specifically Im referring to "pam_check_host_attr" and "nss_map_attribute". It refuses to honor either of these options and I can only assume a number of the other options in our ldap.conf. For instance, "nss_map_attribute" is defaulting to the standard "homeDirectory" rather than "homeDirectoryLinux". This is related to a bunch of OSX clients we have and its not optional to use another setup. The host restriction is also a major issue.
Relevant sssd.conf:
[domain/default]
auth_provider = ldap
cache_credentials = True

I am facing login issues when i try to login as admin using phpldapadmin into ldap server. Installed phpldapadmin for administering ldap server from the repository:

2)yum install phpldapadmin
Able to see the default phpldapadmin login page.
ldapadmin throws the error as "Bad username/password.Please try again"
But when i login as anonymous i am able to login but the web page asks whether to create the root domain?
whether anything needs to be done for making it login as admin.
The details of my set up are as follows:
My slapd configuration:
I have a set of two amd64 machines with Debian Lenny. Machine 2 reads all the users' information from the Machine 1 through LDAP. Also, in Machine 2 I set up a dchroot environment for 32 bits compatibility ( following [URL]
In addition to the above instructions, on this Machine 2, I set up /etc/libnss*, /etc/ldap/*, and /etc/nsswitch.conf both for the amd64 and for the i386 environments. I have no problems if I'm in the native amd64 mode. However, once I enter the i386 dchroot, some strange things happen:
1) For users from uid=1000 to uid=1031, I get an error if running 'whoami' (Cannot find name for user ID XXXX) and if I run 'id' , I get all the correct group numbers but no translation to group names in parenthesis as it should be. 'ls -l' also only lists group numbers but no names.
2) for user 1032 I cannot even change into the dchroot, I get the error "E: Group '1,031' not found"
So I am creating a LDAP server for my school's Linux lab, so users on our school network can log into the Linux machines.
I found a guide here url...Authentication

In researching current ldap issue (not being able to do anything but log in) it seems that there are no concepts of privileges, roles, etc. that could be assigned to a user in LDAP.
I've only seen fields that deal with name, organization, etc., not with application-specific access control.
I have to assign certain access privileges to users authenticated via LDAP server based on the privilege level mentoned in the LDAP server. How to attain this.
