Hi all
I configured cyrus-imapd to authenticate through cyrus-sasl with ldapdb auxprop.
I did all tests suggested on cyrus-imap, cyrus-sasl, and openldap documentacions
but when trying with telnet command I got this error
firewall:/usr/lib/sasl2 # telnet localhost imap
Trying ::1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4 IMAP4rev1 LITERAL+ ID LOGINDISABLED AUTH=CRAM-MD5 AUTH=DIGEST-MD5 SASL-IR COMPRESS=DEFLATE] firewall Cyrus IMAP v2.3.16 server ready
LOGIN test secret1
LOGIN BAD Please login first
I saw all logs, but only showed these lines
Nov 25 18:29:52 firewall master[10454]: about to exec /usr/lib/cyrus/bin/imapd
Nov 25 18:29:52 firewall imap[10454]: executed
Nov 25 18:29:52 firewall imap[10454]: IOERROR: opening /var/lib/imap/user_deny.db: No such file or directory
Nov 25 18:29:52 firewall imap[10454]: accepted connection
it seems that cyrus-imapd isn't authenticating at all with cyrus-sasl
I tested imtest, cyradm, pluginviewer and I got espected results (please see TESTS section below)
I also tested my openldap configurations (proxy configurations) with ldapwhoami command with no problem (please see TESTS section below)
At the bottom of this mail are all the software used and its config files
I don't know what else to do to solve it, please any hint will be appreciated
Fernando
