View 1 RepliesWe have CentOS 5.3 and are using sendmail for outbound emails. We are trying to switch over to authsmtp service. Authsmtp requires sendmail built with SASL suport.
How do I find out if my sendmail has been built with SASL support? If it is not, is it easy to build it with SASL support?
Am unable to send mail from Outlook to my Postfix SMTP server.

I'm using postfix with unix accounts for a while now and I just realized today that SASL authentication, instead of working only with the USERNAME, it also works if the username is followed by ANYDOMAIN.COM
So, let's say I have the following UNIX users: tim, mike, john. If I set the Outgoing Username:[URL]..(where whatever.com can be any name you can think of) IT WORKS, even though it shouldn't, it should only work with tim, mike and john without any domain name. Does anyone know what might cause this and what's the workaround to this problem?
I am running the following on CentOS 5.5 (Final)
dovecot 1.0.7
saslauthd 2.1.22
When I send an email via TLS I see the following log entries.
Code:
Oct 14 11:53:06 ns2 postfix/smtpd[11372]: connect from unknown[172.16.1.159]
Oct 14 11:53:06 ns2 postfix/smtpd[11372]: setting up TLS connection from unknown[172.16.1.159]
[Code]....
What I'm really curious about is there is an intial TLS connection with a 256 bit cipher, but then.. The last entry states "sasl_method=PLAIN" - so surely this is not encrypted? Or am I misunderstanding how it works?
I am re setting up a server of mine running red hat enterprise Linux server 6 and I had all of this working befor but for some reason I had troubles getting sasl to work and now when I login my smtp server I get an error stating that my username or password is incorrect though I am sure I am entering both correctly. Would anyone know what could be happening? I have been spending days on the web looking for the solution and only went from sasl not working when started as a service to this. For some reason I can't use Pam with saslauthd and had to use shadow instead of which from what I hear I get to use better methods of secure authentication with smtp

I have sendmail setup with sasl and multiple domains.I'm sure there is an easy fix for this but I can send emails to anyuser@<anyofmyvirtualdomains.dom> and it will be accepted. I'm just trying to cut down on any confusion that may occur later. Is it possible "restrict" or classify a user into a particular domain? I've setup virtusertable and aliases but no luck in accomplishing my goal.I've searched to find no particular information on this.

I need define a user /password for sasl but want the authentication at runtime be automatic - no explicit prompting the user while accessing a tcp socket with some applications that need the authentication (e.g libvirt)
so I try : saslpasswd2 -c -p -a libvirt <user>
and it hangs (if i now press Enter it says : "invalid parameter supplied") . if I avoid the -p flag the above commad works fine and prompts for password and later when using the tcp it prompts for the above defined user/password and autheticates ok .
But I want without the explicit authentication
The man pages says -p Pipe mode - saslpasswd2 will neither prompt for the password nor verify that it was entered correctly. This is the default when standard input is not a terminal.
In the past (before some upgrading of libvirt via rpm) I had the SASL authentication at runtime done automatically with no explicit prompting the user

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.
