[ERROR] Failed making utility Call to Plesk. Error: [DATE] 53340:65780abbe1688 ERR [util_exec] proc_close() failed ['/usr/local /psa/admin/bin/usermng' '--mod-user' '--old-user=example.example._naza1c1jhjo' '--new-user=example.example._naza1c1jhjo'] with exit code [255]An error occurred during domain update: An error occurred during changing of hosting settings: System user update is failed: Unable to execute usermng: usermng: PAM password change failed: 20, Authentication token manipulationerror
It can be resolved by editing the /etc/pam.d/plesk_usrmng_encrypted file and commenting out the line, password requiredpam_deny.so. Please note that this line is not present in a clean Plesk Installation.The resulting file contents should be:
#password required pam_plesk.so try_first_pass
#password required pam_deny.so
password required pam_plesk.so try_first_pass
