"AuthInfoRequired" in CUPS configuration file "printers.conf" is rewritten in RHEL

Issue

• The AuthInfoRequired parameter was set into none, but it's being rewritten to username,password automatically.
• problems with printer authentication
• We are having problems with the authentication of the printers. Basically the problem consists of the CUPS configuration used in a system without authentication ("AuthInfoRequired none"), but periodically this value changes and stays configured for authentication with user and password ("AuthInfoRequired username,password").
• Currently we are experimenting a problem with the printers.conf file. This file within its parameters has the AuthInfoRequired value as "none" for all the printers; however, it tends to overwrite eventually with the value, "username,password"
