Hi,
Hope you are doing well.
Based on screenshot we can see the "Required Password Quality " section on the "Password Management Basics " tab is set with password quality 8. Whereas the custom policy setting is blank.
"Required Password Quality " section under "Password Quality Settings " in the "Password Management Basics " tab is applicable to Internet password.
Due to this if user try to set the password lower than the value set in "Required Password Quality " section i.e. password quality 8, the Internet password (verse) change will not be successful.
Please refer the following HCL support link for more information about What takes precedence if policy settings configured with “Required Password Quality” and “Custom Password Policies”
Password Quality
Please guide user to use the password matches to value set in “Required Password Quality” option i.e. password quality 8. Based on your business requirement, you can adjust the “Required Password Quality” settings.
I hope the above information will help in answering your queries.
Thanks & Regards
Nishant Shendre
