I just went through a painful upgrade from 8.04 to 10 LTS. I've made a lot of progress but am still having email problems. Dovecot seems to not be able to run, the log is continually reporting:
Aug 22 23:47:34 amd64 postfix/smtpd[22298]: fatal: no SASL authentication mechanisms
Here's this section of dovecot.conf:
auth default {
mechanisms = plain login
passdb pam {
}
[Code]....
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?
Is there any way to provide different methods of authentication on a apache directory (used for webDAV). I need it to use htpasswd and winbind, can't find any guides on implementing them both. Basically domain users need to be able to access the webdav and other users (who will be provided with a username and password NOT on the domain).

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 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 am trying to setup Postfix along with dovecot on RHEL4. I have done the necessary settings in dovecot.conf, yet I am not able to log into the POP3 server. The error I can see through WireShark/Ethereal is "Err- Authentication failed" Some of the important settings in /etc/dovecot.conf are
disable_plaintext_auth = no
auth_mechanisms = plain
auth_userdb = passwd
auth_passdb = pam
auth_user = root
The users/passwords are setup on Linux file system without MQSql or any other database. SASL etc is not configured at all.
