Brian is troubleshooting a Group Policy Object (GPO) that seems to defy the order in which they apply. In Active Directory, Brian has defined different GPOs regarding minimum password length. The organizational unit (OU) GPO dictates the minimum length as 8 characters. However, at his particular facility, the site GPO has the minimum as 10 characters. On his personal workstation, he has set a local override GPO to set minimum password length at 6 characters. Brian believes his password length should require only 6 characters. What is the actual minimum password length of Brian's password?
