Trying to figure out which step is causing me not to be able tologin. I am using a password file,
passdb { driver = passwd-file args = scheme=SHA512-CRYPT username_format=%u /etc/dovecot/passwd }
We will assume that the pw I created using 'doveadm pw -s SHA512-CRYPT' matches the password I will be using to login below. I crank the debugging mode,
auth_debug_passwords = yes auth_debug = yes
And then try to login
[root@mail ~]# nc -t localhost 143
- OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN AUTH=GSSAPI] Howdy a login raub@example.com password [blank]
which from what I gathered from /var/log/dovecot means it found matching username but did not match password:
secured session=lyJttvyQ9I0AAAAAAAAAAAAAAAAAAAAB lip=::1 rip=::1 lport=143 rport=36340 resp=base64-reply (previous base64 data may contain sensitive data) Aug 26 03:25:52 auth: Debug: passwd-file(raub@example.com,::1,<lyJttvyQ9I0AAAAAAAAAAAAAAAAAAAAB>): lookup: user=raub@example.com file=/etc/dovecot/passwd Aug 26 03:25:52 auth: Debug: client passdb out: OK 1 user=raub@example.com Aug 26 03:25:52 auth: Debug: master in: REQUEST 1520959489 26560 1 63ee7f45236f85fd39573a5c8a2eb46a session_pid=26563 request_auth_token Aug 26 03:25:52 auth-worker(26562): Debug: passwd(raub@example.com,::1,<lyJttvyQ9I0AAAAAAAAAAAAAAAAAAAAB>): lookup Aug 26 03:25:52 auth-worker(26562): Info: passwd(raub@example.com,::1,<lyJttvyQ9I0AAAAAAAAAAAAAAAAAAAAB>): unknown user Aug 26 03:25:52 auth: Debug: passwd-file(raub@example.com,::1,<lyJttvyQ9I0AAAAAAAAAAAAAAAAAAAAB>): lookup: user=raub@example.com file=/etc/dovecot/passwd Aug 26 03:25:52 auth: Error: plain(raub@example.com,::1,<lyJttvyQ9I0AAAAAAAAAAAAAAAAAAAAB>): user not found from any userdbs Aug 26 03:25:52 auth: Debug: master userdb out: NOTFOUND 1520959489 Aug 26 03:25:52 imap: Error: Authenticated user not found from userdb, auth lookup id=1520959489 (auth connected 1 msecs ago, handshake 0 msecs ago, request took 1 msecs, client-pid=26560 client-id=1) Aug 26 03:25:52 imap-login: Info: Internal login failure (pid=26560 id=1) (internal failure, 1 successful auths): user=<raub@example.com>, method=PLAIN, rip=::1, lip=::1, mpid=26563, secured, session=<lyJttvyQ9I0AAAAAAAAAAAAAAAAAAAAB>
Per [1] I decided to see what the response (base64-reply) I am submitting to dovecot looks like:
echo 'base64-reply' | base64 -d raub@example.compassword
Which has the right username and password but follows the userpassword format, not useruserpassword as I was led to believe by [1]. Is that to be expected? If it is then the issue is further down the line.
