After working on a new server a few days i cannot login into Roundcube anymore - always get the error “Ungültige Anfrage” - in the logfile of roundcube (/var/log/roundcube/error.log) i found “Plaintext authentication disabled. in /usr/share/roundcube/program/lib/Roundcube/rcube_imap.php on line 211”.
This error seems to be since years - go to /etc/dovecot/conf.d/10-auth.conf and change the line #disable_plaintext_auth = yes
to
disable_plaintext_auth = no
Don’t forget to uncomment. Than a /etc/init.d/dovecot restart and everything works again.
I hope I can give some guys a fast solution for this error.
Must be a OS thing. I’ve never touched that.
During install script there is a question about plain text or encrypted, not sure if it is related.
I always select plain text.
One important difference: we install Roundcube systemwide, so not with the scripts. Why? Because in this case the Server is only a Mailserver and we don’t want to install roundcube on every single domain (because of to many instances). One serverwide redirect to https://server.name/roundcube
You do know that even with script, a user from a different domain can still use the authentication from that other domain. Its authenticating to the mail server not the domain its in. So still systemwide.
