On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Plesk for Linux DoNotDelete:docref kb: fixed kb: bug ABT: Group A

Applicable to:

  • Plesk for Linux

Symptoms

  • Mail accounts with Access to the Control Panel option set in Domains > example.com > Email Addresses > mailbox name cannot log into Plesk GUI with PLAIN password if the password is encrypted in the database. The following error is displayed:

    PLESK_ERROR: Error: You have entered incorrect username or password.

  • The users had an encrypted password before the upgrade:

    # mysql -uadmin -p`cat /etc/psa/.psa.shadow` -Dpsa -e "select mail_name, domains.name as domain from accounts, mail,domains where dom_id = domains.id and mail.account_id = accounts.id and type='crypt'"
    +-----------+--------+
    | mail_name | domain |
    +-----------+--------+
    | admin | example.com |
    +-----------+--------+

  • PLAIN authentication to the mail server itself works without issues, only Plesk GUI login does not work.

Cause

Product issue:

  • #PPPM-1405 "It is now possible to log in to Plesk with an email address account, whose password was encrypted."
    Fixed in:

Resolution

Please consider updating your server:

Workaround

  1. Connect to the server via SSH
  2. Get a list of mail users with encrypted passwords (affected users):

    # mysql -uadmin -p`cat /etc/psa/.psa.shadow` -Dpsa -e "select mail_name, domains.name as domain from accounts, mail,domains where dom_id = domains.id and mail.account_id = accounts.id and type='crypt'"
    +-----------+--------+
    | mail_name | domain |
    +-----------+--------+
    | admin | example.com |
    +-----------+--------+

  3. Change the password for all users retrieved from the list in Domains > example.com > Email Addresses > mailbox name

As a workaround for Plesk 12.5 and Plesk Onyx, use:

Note: This fix below will resolve the issue for encrypted passwords which starts with "$1$".

Note: For Plesk 12.5 the custom fix can be applied without password changing.
