Dear All After struggling last 2/3 days I have been able to setup postfix and dovecot. Through command line, I can send mail out.
Now I have installed roundcube in mail server side, and I am able to access like https://mydomain/webmail.com Login was failing. Then I debugged and modified settings in dovecot and using PAM for authentication. Now I trying to login to email server. I can see that login by dovecot (authentication) is successful, but in roundcube web interface I see 'Login failed". I enabled logging for dovecot. The below logs I get when a user "try" logs in. Oct 21 07:44:55 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Oct 21 07:44:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Oct 21 07:44:55 auth: Debug: auth client connected (pid=15357) Oct 21 07:44:55 auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=128.199.214.27 rip=128.199.214.27 lport=993 rport=43323 resp=AHRyeUBsb2FkbXVsdGlwbGllci5jb20AdHJ5MTIz Oct 21 07:44:55 auth-worker: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Oct 21 07:44:55 auth-worker: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Oct 21 07:44:55 auth-worker: Debug: pam(try,128.199.214.27): lookup service=dovecot Oct 21 07:44:55 auth-worker: Debug: pam(try,128.199.214.27): #1/1 style=1 msg=Password: Oct 21 07:44:55 auth: Debug: client out: OK 1 user=try Oct 21 07:44:55 auth: Debug: master in: REQUEST 1571291137 15357 1 b3cc155dfd3bb2fd576bfeeceaf1ce3d Oct 21 07:44:55 auth: Debug: passwd(try,128.199.214.27): lookup *Oct 21 07:44:55 auth: Debug: master out: USER 1571291137 try home=/var/mail/ mail=maildir:/var/mail/try system_groups_user=try uid=5001 gid=5001*Oct 21 07:44:55 imap-login: Info: Login: user=<try>, method=PLAIN, rip=128.199.214.27, lip=128.199.214.27, mpid=15361, TLS Oct 21 07:44:55 imap(try): Info: Disconnected: Logged out bytes=29/399 >From the logs in bold, one can see (hope I am correct), authentication passed. Now my doubt is, why in roundcube web interface I see Login Fail. Kindly experts please help. Regards Austin
