CentOS 5 :: SSH & Vsftp Authentication From Remote LDAP?
Mar 10, 2011
I try to get authentication working from remote LDAP server (Novell eDirectory)So far I can get correct info from id user or using ldapsearch (so the connectivity is there)But what do I need to configure to get authentication working for SSH login & vsftp login?
I have a centos 5 system with openldap configured. I need openldap for simple user authentication. ie.. to be able to use it for authenticating it from remote applications and systems like mail clients...etc.
I was able to succefully install and configure openldap and ran a slaptest to verify the slapd.conf file for errors and found none. so now all i want to do is to add username and passwords to the ldap database.
iam just not sure what all objectClasses i need to use for Attributes uid and userPassword and what exactly should be the ldif file syntax for the above entries. I tried various sources but i do either get errors while adding or after adding do get errors trying to access it.
above all, iam able to access the ldap server from my phpldapadmin only as a anonymous user and not as a root user that i added as a first entry.
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:
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'm using openSUSE 11.1 and would like to authenticate vsftp users against a mysql database. The newest version of pam-mysql I can find is from 2005. I'm concerned about using something from what appears to be a dead project. Is there an alternative? I'm trying to come up with a solution where I can manage FTP users from an application running from Windows desktops.
i am currently trying to install vsFTP onto my new linux server and btw i just started using linux today this is my first time using linux so i got the ftp installed good it got downloaded and everything then i went to open a port for my server for vsFTP i used this comand to open it "-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT" then i closed it by pressing ESC then :wq! and it brought me back to my comand line again so now when i try to start the ip table thing with the comand "service iptables start" then when i execute that comand putty respondes with this "Applying iptables firewall rules: iptables-restore: line 1 failed [FAILED]"
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 have created a CA on my server then created a server certificate under that then exported it as a common server certificate.I have then gone to my LDAP server and enabled TLS and told it to use the common server certificate.Now on my client I have enabled LDAP TLS/SSL and it's asking me to download a certificate ... from where ? Do I export the certificate to a file and put it on a web server.If so what format as the export offers loads.
I am trying to allow my freshly installed ubuntu 10.04 to authenticate with ldap. I did follow the doc https://help.ubuntu.com/community/LD...Authentication and some other hints with no success.My needs is just to use an ldap existing server (active directory in my site, but i wish to use it via ldap, not via samba/ winbind) to validate users on services using pam modules.After the package installation the command getent passwd retrieve just local users and I don't understand if my ubuntu client is not querying the server or the server reply with some message.
One I cant figure out is a problem of authentication. I'm using open ldap server and try to authenticate a groupware (simple groupware) against it. As it fails, I tested with a ldap client to understand things better. Using GQ ldap client, I 'm able to browse my ldap tree successfully and to search some args from the base DN i specified. but when entering the exact uid as a search string iI got no answer whereas searching the cn returns the correct entry (and display its related entry including the uid I can't find ..) Here is the only thing I can trace in logs (syslog) when trying to seach firstname.lastname (= uid)
I'm trying to get LDAP working with 389 Directory Server on Fedora 13. I have the server all ready to go, and I can query it with the 389 console. But when I tried to move on to the next step, user authentication trough LDAP, it just won't work I followed the PAM Howto, but the given authconfig command doesn't work. If I manually add a user with the 389 console, I can't login with it.Since I had X11 forwarding working over SSH, I tried authconfig-gtk. I setup a SSL LDAP connection for this to work, but it still didn't work. I did have this working on my (now crashed ) Fedora 12 VM.
I installed Nconf software on a Debian server.I am trying to configure Nconf Authentication with LDAP.I edited nconf's authentication.php file accordingly and I installed php5-ldap package.When i enter user-name and password in Nconf's login screen.
I've added a new machine (desktop used by many users) to a network that uses LDAP (pam_ldap) for authentication. Can anyone post relevant configs to limit users by a groupOfNames? I've googled extensively and have found some partial comments, but no complete config examples or howto's.
The issue is as follows:
All users have one primary GID in their posixAccount entries, which is used to control access to the existing machines. So it's not really possible to change this. Now, I need to limit access to this new machine to a specific subset of users, all members of a specific groupOfNames. I can't seem to get pam_ldap to use a groupOfNames instead of a posixGroup.
We have an LDAP server (OpenDirectory on Snow Leopard Server--OpenLDAP essentially) and I am trying to configure our slackware hosts to use that LDAP server as the authentication mechanism instead of NIS/YP as they currently do.How do I change it, and is it just as simple as changing /etc/nsswitch.conf?
On this moment i configure a testenvironment with 1 Microsoft active directory server and 1 Opensuse 11 samba filesharing server. But i have a issue. The samba server is add to the domain and the servers can communicate with eachother. I can login to the domain on the samba server and the LDAP settings tab on yast2 samba configuration tool tell me that samba and the MS LDAP server can communicate with eachother. I can see the shares on the samba server but i can't autenticate myself. When i whant to logon than see i always "domain: domainname.local" and "access denied". My question is now how can i give the MS administrator account rights to view the shares and configure the rights for the other users.Samba config file
I've just installed Ubuntu Server for the first time with the goal as setting it up as a proxy server for our Apple computers here since I can get neither ISA of OS X Server's firewall to play properly. So far I have the machine authenticating against our OS X OpenLDAP server and multiple NIC's setup ready to be connected to the outside world. My question is does anyone have a preference on what proxy I should be using? So far my search efforts seem to of turned up Squid Proxy as a favorite among Ubuntu users but I can't seem to work out how to get it authenticating against my OpenLDAP server.
i am taking another stab at this. The last time i attempted it, it seemed like everyone had a different way to do it, but nobody could give me an answer on how to do it...
I currently have a Domain Controller Running sme server and a domain controller, using ldap as a backend. I have two file servers runing ubuntu 10.04. My overall goal is to have it so when i create a username on the domain controller, it is then automatically copied over to the fileservers. This way everyone will have their own username and password to access the fileservers and ill be able to track what people do on the fileservers.
The next necessity is for me to be able to apply permissions to the folders on the fileserver based on the users that are created on the domain controller.
LDAP Authentication for Web Access I am trying to build a LDAP server to allow access to the wireless network in conjunction with Meraki wireless access points. I am using Ubuntu 10.10 and trying to install OpenLDAP from their documentation but I keep running into the error "configure: error: MozNSS not found - please specify the location to the NSPR and NSS header files in CPPFLAGS and the location to the NSPR and NSS libraries in LDFLAGS (if not in the system location)" I have OpenSSL installed but I also got these when I ran ./configure

I have installed openldap version 2.4.21 and configured with the help of the site [URL] and the LDAP address book is working fine. But I need to create an LDAP directory such that it will contain the user name and passwords for the users and when user is logging to any application he is authenticated from LDAP directory
e.g Users who need to browse the internet need to authenticate with username and password for access from the firewall (Juniper Netscreen) and similarly other applications like oracle ERP such that they will have only 1 username and password stored in LDAP directory and all other applications will search for the user name and password for authentication.
I Configured LDAP Server on ubuntu Server 10.04 ,(using url ldap) and Client also it's working fine. After that I changed to ssl encryption and create certificate in server side. Now it's not authenticating from server it's shows Incorrect Password, but I can login though terminal if I am root user ,then it not ask any password it's logon to ldap user. After I changed to ldap server to ssl encryption and made one changes in client side uri ldaps://ip-address/ (/etc/ldap.conf).
I have more than 150 Linux desktop computer in my office IT setup.
I want to configure LDAP centralize network authentication for all the desktop computer.
My requirement is below mentioned.
The LDAP server will only authenticate the desktop computer at the log-in time when the user start computer.
The home directory of all the user should be create in their desktop local computer not in the LDAP server.
And flexibility of user log-in for every desktop. (any user can log-in any computer with his/her username and password)and the home directory will create automatically in the local desktop computer automatically the moment any user will log-in to any computer in the network and the LDAP server will authenticate for desktop-network log-in in to the computer.
Install and configure Samba as a primary domain controller with LDAP on Linux.i setup it step by step following article without error until step 10.i want to join windows client when press user name and password for domain then display message:The following error occurred attempting to join the domain BIGTIME: The network path was not found.
I'm having a pretty weird problem, and really have no idea where to begin in tracing and fixing it. But here goes.I'm running Ubuntu 10.10 on 2 machines, and have installed OpenLDAP as per the guide https://help.ubuntu.com/10.10/server...ap-server.html it all seemed to be going well having it installed and running on Server A, including authentication. So a few days later I decided to setup server B to be a slave replica. Which after a little bit of fiddling seems to working and keeping the records in sync.
Then I did an apt-get upgrade on server A. then my problem started.Basically getent passwd, only returns one entry from the LDAP and so does getent group.But a search of LDAP returns everything that's there.I've been comparing the config files between Server A and Server A for PAM etc, and everything is the same.but if I change ldap.conf on server A to point the uri ldap://server B/ and rerun getent passwd it returns all the users and getent group returns all the groups.I've compared the LDAP entries between Server A and Server B and they're staying in sync.It looks like it's more to do with ldap than the auth config if just changing the server fixes it, but as server A is the master LDAP server I'm really at a loss.
If getent was only returning local users it'd be something, but it's returning local + 1 LDAP user or 1 group. Which just seems weird.Any help would be greatly appreciated. I'm sure posting some logs would be helpful, but I have no idea which so if someone can let me know what extra info would be more helpful I'll post it back asap.
I have an issue with Apache2 and ldap authentication. Here are the specs: Linux 2.6.32-24-generic i686 GNU/Linux Ubuntu 10.04.1 LTS Apache/2.2.14 (Ubuntu) PHP/5.3.2-1ubuntu4.5 with Suhosin-Patch configured
I have installed our site onto a newer server as we were previously running SLES 9.3. The site has installed correctly, however, It seems to be serving the pages a hell of a lot slower than SLES (eventhough the specs etc are much improved). The main problem seems to be with Ldap - sometimes taking 2 or 3 minutes before authenticating/serving the user - and sometimes one minute it works, another minute it doesn't! We know it's a problem specific to this Ubuntu machine, as the older server has no issues with ldap whatsoever. Also, sometimes the ldap authentication fails all together with a timeout, resulting in a 500 status code. I'm not sure whether this a problem with the apache config, the network settings or the server setup. We know ldap itself is fine.
Here's the /etc/apache2/sites-available/default config for ldap. Are these directives correct? (I know a lot of changes were made between apache2 and apache2.2 that may affect this config): Code: ScriptAlias /home/ "/var/www/cgi-bin/" <Directory "/var/www/cgi-bin/"> AuthType Basic AuthzLDAPAuthoritative On AuthBasicProvider ldap AuthName "Active Directory Authentication Required." AuthLDAPURL "ldap://x.x.x.x:3268/DC=xxxxxx,DC=com?userPrincipalName?sub?(objectClass=*)" NONE AuthLDAPBindDN "firstname.lastname@example.org" AuthLDAPBindPassword xxxxxxxx require valid-user Options +ExecCGI -Includes AllowOverride None </Directory>
Here's some examples of some of the log messages we have been receiving: 1. This one occurs upto ten times in a row when the client is being authenticated: Code: [Thu Nov 04 12:47:19 2010] [debug] mod_authnz_ldap.c(377): [client x.x.x.x]  auth_ldap authenticate: using URL ldap://x.x.x.x:3268/DC=xxxxxxx,DC=com?userPrincipalName?sub?(objectClass=*), referer: http://x.x.x.x/home/page
2. This is output when the authentication works: Code: [debug] mod_authnz_ldap.c(474): [client x.x.x.x]  auth_ldap authenticate: accepting email@example.com, referer: http://x.x.x.x/home/page
3. And this one is always output after the error above. This one is more interesting. What does this mean exactly? And why does it say 'declining to authorise' directly after saying 'accepting firstname.lastname@example.org'? Surely this makes no sense: Code: [debug] mod_authnz_ldap.c(546): [client x.x.x.x]  auth_ldap authorise: declining to authorise (no ldap requirements), referer: http://x.x.x.x/home/page
4. This one is output when the authentication attempt times out (after 10 outputs of error number 1): Code: [warn] [client x.x.x.x]  auth_ldap authenticate: user email@example.com authentication failed; URI /home/page [LDAP: ldap_simple_bind_s() failed][Can't contact LDAP server], referer: http://x.x.x.x/home/page
I am posting this as I have tried several times to work this out. I have read article after article, post after post and tutorial after to tutorial to sort this issue. I have an Ubuntu 10.04 machine running as the LDAP and NFS server with two Opensuse 11.3 desktop machines. Both of the Opensuse machines can login using the LDAP server for authentication and this works fine. The server also exports the NFS Shares no problem but I am unable to mount the shares from the Opensuse machines. I have been using Yast, NFS Client to mount them.
Yast NFS Client can see the shares and lists them however when I apply the settings it states:
'Unable to mount entries in etc/fstab' I need to mount the shares according to the LDAP details as I want the users to be able to access their files no matter which machine they login at. Can anyone shed any light on the issue. Any help would be great and I would be enternally grateful as I am now beginning to pull my hear out slightly.
I would like to know whether ldap can be used to authenticate wireless clients with my server.server and clients are connected to a wireless router and i am able to get wireless adapter work in my ubuntu. Is there any anything extra which is required or the openldap server will work for wireless clients?
