similar to: Enable IMAP only for certain users/IP

Hello, I have a problem to which I have not been able to find a solution by myself or online. I have Dovecot running together with Qmail on a CentOS server. I need to be able to control which users are allowed IMAP access and at the same time allow IMAP access for all users when the requests are coming from a specific IP. My problem has two parts, detailed below.

Hi, I'm trying to use pam_listfile.so to deny logins from all others but few users (names in /etc/loginusers). With password authentication it works fine, but with public key authentication OpenSSH lets in users whose names arent't in /etc/loginusers. AllowUsers in sshd_config does what one would expect. I'm using OpenSSH-3.0.2p1 on Debian testing (package version 1:3.0.2p1-6)

hi all, i'm setting up Dovecot on OSX to use PAM authentication against a flat_file/static userdb (tho i will _eventually_ mv to pgsql ...). iiuc, to do so i need something like: =================================== (EDITOR) /etc/pam.d/dovecot.imap auth required pam_listfile.so item=user sense=allow file=/var/dovecot/imapusers onerr=fail =================================== for a userdb

Hello. Tried search, no luck, sorry, if this is already answered, but I'm still looking a solution using pam_auth how to define in dovecot which user can access which protocol, for example, default is: protocols = pop3 pop3s imap imaps I'd like to use something like this: exclude_using_pop = user1, user2, @group exclude_using_pops = user1, user2, @group exclude_using_imap = user1,

Hi folks, I can't seem to log into my system via vsftpd. All other services using PAM are fine...Am I missing something simple? ftp> user (username) user 331 Please specify the password.

Hi, I have tested the current snapshot portable release (dated Jan 9 2004). configuration has: UsePAM yes PasswordAuthentication no ChallengeResponseAuthentication yes UsePrivilegeSeparation yes two problems: first pam_motd does not work anymore. second, I needed a quick way to disable normal user logins without disabling admin accounts (members of group wheel). the best option i could come

I'm using libvirt in desktop environment. Single host machine, pair of users, a few guest machines. The first thought was that unix socket restricted to specific group is just enough for authentication. But virsh has the power like sudo: you could define pool on real device and write anything on it. So I decided to authenticate with password for each virsh use. I'm using SASL + saslauthd +

Hi, I'm trying to control access to different services on an Debian server using /etc/group. So that a user I create for FTP usage doesn't fill up my server with IMAP folders or samba garbage. Services like proftpd have: "AllowGroup ftpgroup" sshd have "AllowGroups sshgroup" And samba have "valid users = @smbgroup" But I can't find the correct

Hi, I am running dovecot on Fedora Linux in our organization and use IMAP as well as POP3 protocols for mail retrieval. I want to impose the following user based restrictions: (a) I want to permit only selective users to access either POP3 or IMAP server or both. (b) The server can be accessed from LAN as well as WAN. However I want to allow only selective users to be able to access POP3 or

Greets ... I am not getting it. I have samba (old one, 3.0.22-11-SUSE-CODE10) in an ADS-context, winbind works OK ... I am trying to connect vsftpd to winbind via PAM, this works TOO GOOD ;-) currently I am able to login to vsftpd with ANY password, that's bad. I am not understanding that PAM-stuff and I have some pressure to get that ftp-server up, so please would someone help me out? My

We use samba 2.2.9 with winbind. We use winbind for authentication. I was able to selectively limit pop3 use among winbind users on redhat 9 with this pam configuration. (As you would use it in ftpusers, in the reverse sense.) auth required /lib/security/pam_listfile.so item=user onerr=fail sense=allow file=/etc/pop3users This is the best solution for my situation, and I want to have that on my

I have my Redhat 5.4 linux server fully integrated into my companies AD.? The biggest issue I have is that I am using a rid backend which means that anyone with an AD account can log into the server.? So my quesiton is, how can I restrict server login via AD groups?? I have tried using pam?with pam_listfile, but for some reason it does not work, I keep getting errors about sshd refusing the user.?

I'd like to toss a feature request on the table for consideration. We currently use a different popd because of a feature that allows us to restrict pop access based upon an allowed users list. This is the only thing that keeps us from using the popd in dovecot currently. It's a simple text file of usernames that are allowed to use pop, if the name isn't in that list then pop

Hi, I am currently trying to configure AD (Windows 2003) + Linux (CentOS 4.4) to allow user logins for certain users, namely, developers. The winbind authentication part of it is working correctly, but every user in AD can login to the servers via ssh. I have tried to limit users by adding valid_users = @"domain+developers" (+ is the separator) on /etc/samba/smb.conf, but this

I would like disable password authentication in sshd for particular users, without locking their UNIX password, and without requiring all users to use PubkeyAuthentication. I cannot find a documented way to accomplish this in OpenSSH. Is it currently possible? If not, I think this would be a very useful feature to add. I believe that each user should have some control of which authentication

Hello! I was wondering if it possible now (or possible to implement something like that in the future) that the daemon does only accept connections if a specific file is present at the moment of the connection request. I want to achieve that a connection to my server is only possible if I plug in e.g. an USB stick (which would contain the file) and is always rejected if that
