Hi,

We've installed iRedMail on a machine running Ubuntu 18.04 using LDAP as backend for accounts. The LDAP is used as well as backend for a moodle and nextcloud installation. Unfortunately we discovered a problem with the encoding in Roundcube/the mail server.

We create our users using a shell script which encrypts the password with SSHA. It works great. At least that's what we thought. But unfortunately we found out now that we get problems if we e.g. use umlauts in the password (ä,ö,ü) and change or set the password in LDAP via shell.
If we do this, users will still be able to login to NextCloud and Moodle, but not to Roundcube.

A similar problem occurs when users change their password. Our users usually do this in Roundcube. However, if they use an umlaut here, they can log in to Roundcube with the new password but no longer to the other services connected to LDAP.

Seems to be a bug. Is the encoding set incorrectly per default in Roundcube/the mail server?

Thanks in advance!
