Hi all
I finally got work cyrus-imapd with cyrus-sasl (and with openldap as backend to authenticate users)
I did telnet tests to both pop and imap services from localhost and worked great.
but when I tried to do the same tests from other machine authentication fails:
mail:~ # telnet 192.168.1.1 143
Trying 192.168.1.1...
Connected to 192.168.1.1.
Escape character is '^]'.
* OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID AUTH=PLAIN AUTH=CRAM-MD5 AUTH=LOGIN AUTH=DIGEST-MD5 SASL-IR COMPRESS=DEFLATE] firewall Cyrus IMAP v2.3.16 server ready
imap LOGIN test secret1
imap NO Login failed: authentication failure
. logout
I checked logs and found that openldap got authcid as: 'cyrus@joan.com.bo' instead of only 'cyrus' (my new proxyuser) (LOGS below)
I have joan.com.bo configured in other linux server with named service installed and running for the LAN
so I think that when doing pop and imap tests from any other computer from LAN but localhost, the user sent from telnet to the server is filled up with that domain.
Is there a way to bypass this? or a way to fix this problem?
I know that cyrus-imapd can handle more than 1 domain, so I guess that it's probably a misconfiguration in openldap or cyrus imapd (CONFIGURATION FILES below)
I also left OPENLDAP DATA at the bottom of this mail.
Thanks in advance for any suggestions.
Fernando
