I Installed the fresh cyberpanel installation when I created a email with the domain and tried to login with the same it shows
Authentication failed
Server message: AUTHENTICATIONFAILED Authentication failed.
I am using VPS server from contabo:
OS: Ubuntu 18.04 (64 Bit)
Installed Cyperpanel using below command.
sh <(curl https://cyberpanel.net/install.sh || wget -O - https://cyberpanel.net/install.sh)
When I checked for the errors I got below Error:
Sep 14 19:44:42 vmi1011202.contaboserver.net dovecot[733]: auth-worker(1939): Error: sql([email protected],127.0.0.1,<TgoNr6boGLp/AAAB>): Invalid password in passdb: crypt() failed: Invalid argument Sep 14 19:44:44 vmi1011202.contaboserver.net dovecot[733]: imap-login: Disconnected (auth failed, 1 attempts in 2 secs): [email protected], method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, TLS, session=<TgoNr6boGLp/AAAB>
This was because of dovecot version once we upgrade devecot from 2.2.x to 2.3.x it'll work.
Follow below steps.
Add the reposity key of dovecot to the rpm key store:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 18A348AEED409DA1
Add the official dovecot Ubuntu Repo to sources.list (this example is for Ubuntu 18)
sudo nano /etc/apt/sources.list.d/dovecot.list
insert into:
deb [arch=amd64] https://repo.dovecot.org/ce-2.3-latest/ubuntu/bionic/ bionic main
Save it and close editor
Do a:
