    I upgrade a server with courier to cpanel 11.40 then switch to dovecot. Strange errors appear on authentication and blank webmail pages:

    /var/log/maillog

    Code:
    Nov  7 07:35:39 s5 dovecot: auth: Fatal: execv(/usr/local/cpanel/bin/dovecot-wrap) failed: Permission denied
    Nov  7 07:35:39 s5 dovecot: auth: Error: checkpassword(user123@domain.dom,123.123.123.123,<YK7Loo/qTQCynLG/>): Child 15910 exited with status 84
    Nov  7 07:35:41 s5 dovecot: pop3-login: Aborted login (auth failed, 1 attempts in 2 secs): user=<user123@domain.dom>, method=PLAIN, rip=1
    Code:
    # ll /usr/local/cpanel/bin/dovecot-wrap
    -rwsr-x--- 1 root root 9176 Nov  6 22:25 /usr/local/cpanel/bin/dovecot-wrap*
    
    /usr/local/cpanel/logs/error_log
    Code:
    PHP Fatal error:  Call to undefined function logout_error() in /usr/local/cpanel/base/3rdparty/squirrelmail/plugins/login_auth/functions.php on line 282
    
    Upgrade to 11.40 was 100%completed with no error. No client was able to authenticate on pop3/imap. Switched back to courier until you fix this error.

    Please open a ticket using the link in my signature. This problem is likely a symptom of a problem with your system's rpm database. The correct permissions for dovecot-wrap on 11.40 are as follows.

    # ls -l /usr/local/cpanel/bin/dovecot-wrap
    -rwsr-x--- 1 root dovecot 9176 Apr 9 2013 /usr/local/cpanel/bin/dovecot-wrap*

    From your message, looks like the group was not set to dovecot. I set it, swith back to dovecot but now all users get authentication error:

    Code:
    dovecot: pop3-login: Disconnected (auth failed, 1 attempts in 2 secs): user=
    It happens again on a distinct server where automatic updates ran few hours again.

    Ticket means remote connection to server and debugging. I cannot do this for a production server.

    yum update reports no update. /usr/local/cpanel/scripts/check_cpanel_rpms --fix run with no message.

    I had the same problem and fixed it with this command:

    Basically fixes the missing permissions problem.

    I hope that helps someone.
