Ubuntu Installation :: Cannot ID LDAP User On LDAP Client
Dec 2, 2010
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 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 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:
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:
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 have 389-DS ( Fedora DS) setup on CentOS 5.3 and working fine. I configured LDAP Client and want to login as user created under fedora DS Client. From Client Machine, I can easily see: Code: [root@fedoraDS-Client ~]# id ajrain uid=569(ajrain) gid=569 groups=569 context=root: system_r:unconfined_t:SystemLow-SystemHigh
This is User from LDAP Server (fedora DS Server) which is showing in Client Machine. So It means its retreiving value from Server. Correct? Now When I am trying to login , it says "Server unexpectedly closed network Connection". When I supplied user password: Code: login as: ajrain ajrain@fedoraDS-Client's password:
The File /var/log/secure says: Code: Jan 27 02:39:27 localhost sshd[3996]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=10.210.53.104 user=ajrain Jan 27 02:39:27 localhost sshd[3996]: Failed password for ajrain from 10.210.53. 104 port 1241 ssh2 Jan 27 02:39:27 localhost sshd[3997]: fatal: Access denied for user ajrain by PAM account configuration
I am facing problem in adding new users in ldap server and client for a long time. I configure ldap server and client successfully and I can login the client machine by a user. User is created on server during configuring the server but after same time when I create a new user on server and create a home dir for the same user on client machine and assign 700 permission on home dir of same user and copy the /etc/skel/.* /home/user-dir and when run the command "#chown -R user:users /home/user" it shows invalid user error.
how to make a new Ubuntu 9.10 box use our LDAP/Samba server for user authentication. Our Red Hat and Windows machines all use it just fine. I've been trying to use the auth-client-config and libnss-ldap packages for this purpose, but I must be missing something. I'm pretty green with LDAP, so this is my first time diving in... Is there a good How-To or step-by-step read on this? All of my searches lead me to setting up Ubuntu as the server, and that isn't what I want. I've also tried the steps listed in [URL] for the LDAP Authentication section.
I have configured LDAP Server on RHEL 5.2 successfully and client can login to the server. But I do no how a client can change its LDAP password on his client machine.
I have a openldap server running on one machine (fedora10) and pam_ldap.so and nss_ldap.so running on the other machine.
I have added a new user to the LDAP server database, this user is not created on client machine.
1. Can i login to the client machine using this new user?
2. Now if i try logging with this new user I am getting error messages, the error messages are as follows at client side
Sep 2 10:34:36 localhost sshd[8484]: Invalid user kim from 10.254.194.148 Sep 2 10:34:36 localhost sshd[8485]: input_userauth_request: invalid user kim Sep 2 10:35:16 localhost sshd[8484]: pam_ldap: error trying to bind as user "cn=min soo,ou=people,dc=samsung,dc=com" (Invalid credentials)
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:
I've followed the Host Based Authentication Part from this page: [URL]...I cannot get it to work. When I delete the 'ldap' from the shadow line in /etc/nsswitch.com all my ldap users cannot login. Yes I've uploaded the ldapns.schema, activated hostObject and added the machine name to the host attribute to my test ldap users. I get this error from /etc/auth.log: sshd[3979]: pam_ldap: ldap_initialize Bad parameter to an ldap routine
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 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'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'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.
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.
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 am getting a problem that whenever I loged in with my ldap user on a ldap client and try to change the password of ldap user it doesn't allow me to do so...
azizf@pc:~$ passwd passwd: User not known to the underlying authentication module passwd: password unchanged azizf@pc:~$
We have several FC machines (from 6 to 12) that use an OpenLDAP server running on Centos 5.4 for authentication. I have now tried setting up a FC13 workstation. I notice that the authentication GUI has changed and wants me to use Kerberos or a TLS enabled server. Is there a way to get FC13 to behave like FC12 in this respect. Or (less desirable) what changes do I have to make to the server to accommodate FC13?
The workstation knows who the users are, but will not authenticate if they try and log in.
I have 389 fedora Directory Server which is nothing but LDAP Server running on 389 Server.Its working fine on CentOS. Now I am in search of script which can be put on boot time so that the new Machine can automatically come under LDAP Client.Generally the machines are RHEL 4/5.
I have configured ldap client on openSUSE 11.3 with yast2config. Since I am able to get list of all users through getent, it seems configuration done properly. But while logging in with ldap id its prompting for password change.
Code: login as: testuser Using keyboard-interactive authentication. Password: Using keyboard-interactive authentication. Your password has expired. Choose a new password. You are required to change your LDAP password immediately. Enter login(LDAP) password: I have other solaris machine as ldap clints, which are working fine. Do I need to change any pam config?
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.
how to login with ubuntu ldap server account from ubuntu client(karmic). Ubuntu server and client setup is done properly but not knowing how to login to ldap server graphically from ubuntu client. I don't want to login via SSH
(This was posted at the end of another thread, where it probably didn't belong, so reposting here)I have Active Directory set up on one machine (and I can't really adjust the settings very much) and Ubuntu Server 10.04, which I would like to use as a client.I followed the directions at https://help.ubuntu.com/community/LD...Authentication, but when I get to
Code: getent passwd I don't see anything from the LDAP, and ssh'ing into the box from an LDAP/AD username certainly doesn't work.
In addition, I've attempted to use Webmin's LDAP Configuration module to configure it. I can connect to the server and can browse it with the LDAP browser with my settings, but the Webmin package doesn't recognize the users (which are organized in one of four Organizational Units (OUs) within the OU that I have as my Search Base) as users,
I have an LDAP server holding user/pass/group for many users. Due to network issues, the server sometimes is unreachable and clients cannot login, current sessions usually freeze after a while. All client have ubuntu 10.04.2 x64.
I have went through the outdated howto to cache the LDAP credentials.
I setup the required packages daily cron "nss_updatedb ldap" and edited '/etc/nsswitch.conf' to have "files ldap [NOTFOUND=return] db" for both passwd and group.
I'm new LDAP kind of stuff.I want to configure LDAP server and Client on windowsXP. could you tell me which Open source LDAP Server and client are best fit for windowsXP. Is OpenLdap not suitable for windows?
