Hello good morning everyone, after performing the v84.0.12 update, I am having some problems, some email accounts are not authenticating. I get error 401, as in the log below. 1x.8x.x2.1x - vendas%40xxxx.com.br [11/19/2019:12:35:33 -0000] "POST /cpsess6801626870/3rdparty/roundcube/?_task=mail&_action=refresh HTTP/1.1" 401 0 ": 550 5.1.1 User doesn't exist: xxxx@xxxx.com.br"

  Hello, This is an issue we're aware of and currently working to resolve as upon updating to version 84.0.12, many email users found they were unable to authenticate, as well as inbound emails reporting 'No Such User'. This is occurring due to Cpanel::PwCache::Find
  not being able to handle shadow files with invalid bytes. Right now the only viable workaround is the following: cp -av /home/$(/scripts/whoowns domain.tld)/etc/domain.tld/shadow{,.bak} dos2unix /home/$(/scripts/whoowns domain.tld)/etc/domain.tld/shadow

  Login log was showing that the hash didn't exist as well. /usr/local/cpanel/logs/login_log FAILED LOGIN webmaild: user password hash is missing from system (user probably does not exist) Seems the /home/CPANELUSER/etc/DOMAIN.TLD/shadow file was not updating the \@pwcache/USERNAME file either.
