Symptoms

Customer cannot change property of his domain. Any domain modification fails with the error:

Error: system user update is failed: Unable to execute usermng: usermng: PAM password change failed: 20, Authentication token manipulation error System error 111: Connection refused usermng: Failed to set password for user 'user_name' System error 111: Connection refused

Cause

This error is caused by system misconfiguration. Record  for the domain FTP user is missed in the file /etc/shadow.

Resolution

Check if the record about domain FTP user exists in the files /etc/passwd and /etc/shadow.
# grep ftpuser /etc/passwd
ftpuser x:10001:2523::/var/www/vhosts/domain.tld:/bin/false
# grep ftpuser /etc/shadow
#

Use the domain FTP user name instead of ftpuser.

Missed entry on the file /etc/shadow can be fixed with the utility pwconv.
# pwconv

This utility creates shadow from passwd. Missed record for user should be created. 
# grep ftpuser /etc/shadow
ftpuser:$1$cwJm/Trv$2UFLfaAlsvmFzvc6rzJP.0:15455:0:99999:7:::
