I'm having a problem whereby I'm able to send mail to a mailbox from several different email addresses and SMTP servers (gmail, RoadRunner broadband), but I'm unable to send mail to the same address from one particular account, the SMTP server for which runs on a mediaTemple (dv) 3.0 box with CentOS 5 Final.I've spent a full workday on the forums, trying to troubleshoot the issue, and I'm running out of ideas.The server on which I'm having the mail processing problem is a mediaTemple (ve) running Ubuntu 10.04 x64 (Linux 2.6.18-028stab070.7 #1 SMP Fri Oct 1 13:53:00 MSD 2010 x86_64 GNU/Linux), with ISPConfig 3.

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.
True or False: If you have a user on your Linux/Samba machine with a password, example:
User = Bob
Password = Password0
And Bob is on an XP computer, where his username is also Bob and his password is also Password0, is it normal for Bob to go to:
\SambaServer, double click on Bob's share (valid users = Bob only) and Bob get RIGHT in without being prompted?
On my prior setup, the user HAD to log in. If they wanted auto login next time with their credentials, they had to check "remember password." But now it's as if Samba knows who they are. It's very strange. What's the normal behavior? Must EVERYBODY authenticate with passwords, or if the Windows credentials are the same as Samba does it just somehow auto-detect it and allow them through?
I want to make changes on my router bios for my server I have to go to my windows booted laptop rather than just 192.168.1.1 right here at my server. I only have to do a 360 in my chair and I am at my laptop but I don't want to. Everytime I type the gateway ip it reads off the name of my router and looks fine. But I enter my authentication info and it just returns the login window blank... something ubuntu-side?
WRT160v2 linksys wireless N router (Of course I have cat 5 running to my server)
Ubuntu 10.04 LTS running desktop ontop (because I am still learning how to navigate the console)
Im using linux (Suse 11.1) on my laptop in my new job, however I need to set up my accounts and any account to authenticate using the existing windows ADC server.
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.

I'm trying to expand my Courier+MySQL+Postfix+PostfixAdmin server to use SASL logins on Postfix so I can relay on my server. After following several guides I still can't get it to work: Postfix logs show the user transcript and end with "Authentication failure" but it does not tell me what told it that the login failed. The messages log show this:
Feb 19 22:48:55 sportlaan-server saslauthd[7254]: do_auth : auth failure: [user=berend] [service=smtp] [realm=mydomain.com] [mech=pam] [reason=PAM auth error] Which I don't get because I don't think it should be using PAM... I think...
The setup is similar to this one: http://www.howtoforge.org/virtual_users_postfix_courier_mailscanner_clamav_centos_p6

I'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.
I am wondering how websites like banks are able to determine if you have previously used a certain computer to access the website, even if your router's IP address may have changed and your system's cookies have been cleared. I have users that need to access our HTTP intranet from outside locations. Those locations will have dynamic IP addresses most of the time, so I can't just "allow from [ip]" in my Apache proxy configuration. Originally we considered a VPN, but determined that a VPN will be overkill to access just an internal website, since we do not want external users to have permission to the rest of the network, only the website.I currently have it working over HTTPS with basic authentication against an internal LDAP server, but I want a little more security for such an important website.

View 2 Replies View RelatedWe have a small group of linux servers, currently with local logins. I want to eliminate the local logins and authenticate against the corporate AD. I've been looking at PAM - but winbind requires each machine to be added to the AD. This becomes a pain if we create new virtual or physical servers. Is it possible to have one server authenticate directly with AD, and the other servers authenticate against this server, which defers to the one server that is registered in AD?

i need to find a way to securely authenticate a decryption mechanism of some sort where the authentication is provided remotely without any user-interaction. Right now i have a number of boxes that all inform a central server when they are online. When they do this an OpenVPN connection is set up between them and the server.
However, i have been given the task to ensure that the scripts involved in this process are encrypted by default. This requires some form of self-decryption, which to my mind kind of goes against the whole idea of encryption/authentication in the first place. I need some way to leave decrypted the bare essentials required to boot a box and securely connect to the central server automatically. Then the server would automatically send a key/passphrase and the rest of the files on the box would then be decrypted on the fly.
This is installed and I get this error. I am attempting to install razor-agents 2.84 and get this error along with: Warning: prerequisite URI::Escape 0 not found.
Both of these were install in CPAN. When I attempt to install them again, they say they are up to date.
How can I make the user in remote LDAP server to be used to authenticate Local Linux server ?

I am struggling to get dspam to work properly.
I have follow the instructions [URL] to the letter but when I send spam/ham to the ham@mydomain.net address I see a problem in the logs.
The problem appears to be that when dspam filters the mail it stores the digests in:
/var/spool/dspam/data/mydomain.net/<user>
But when it tries to find the digests to add them to the spam/ham database it looks in:
/var/spool/dspam/data/local/<user>
But I can not find anywhere in the config that controls this.
As I followed the instructions on the ubuntu forums I can not be the first person to see this problem.
