hello,

I'm new to this forum:) I couldn't found any topic with the same problem and I'm sorry for the inconvenience if there is already one.

I'd like to use Dovecot with an authentification from Samba4 via Kerberos. I've followed this procedure : http://wiki2.dovecot.org/Authentication/Kerberos but I cannot connect to the domain.

I have not met any difficulty with Samba ; I have others servers that are connected to the samba4 domain via samba/winbind

wbinfo -u / -g et getent passwod / group works fine.

I don't find the error and the logs are fruitless :

Oct 4 09:03:46 mail dovecot: imap-login: Aborted login (no auth attempts

in 0 secs): user=<>, rip=MY_IP, lip=IP_SERVER, session=<4ilrqQQ+2AAKaBFq> Oct 4 09:03:46 mail dovecot: imap-login: Aborted login (no auth attempts in 0 secs): user=<>, rip=MY_IP, lip=IP_SERVER, session=<7SprqQQ+2QAKaBFq> Oct 4 09:03:55 mail dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=MY_IP, lip=IP_SERVER, session= Oct 4 09:03:55 mail dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=MY_IP, lip=IP_SERVER, session=

This is my docevot -n

# 2.2.13: /etc/dovecot/dovecot.conf
# OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.6
auth_default_realm = DOMAIN.COM

auth_mechanisms = gssapi

}
prefix =
}
plugin {
sieve = ~/.dovecot.sieve
sieve_dir = ~/sieve
}
protocols = " imap pop3"
ssl = no
userdb {
driver = static
}

I wish to use maildir and I wish not to have multidomain. The server is a Debian 8 with compilated samba 4.4.5 + dovecot 2.2.13 (deb file).

i dovecot-core - secure POP3/IMAP server - core files
i dovecot-gssapi - secure POP3/IMAP server - GSSAPI support
i dovecot-imapd - secure POP3/IMAP server - IMAP daemon
i dovecot-pop3d - secure POP3/IMAP server - POP3 daemon
i dovecot-sieve - secure POP3/IMAP server - Sieve filters su

And this is what telnet returns :

telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE

IDLE LOGINDISABLED AUTH=GSSAPI] Dovecot ready.

Can you give me a hint, please ? Thank you !
