In Cisco UCS, modifying user accounts involves several considerations. Disabling a user account does indeed maintain all the data in the Cisco UCS Fabric Interconnect, which means that the user's settings and privileges are retained even though the account is inactive (A). Local user accounts have precedence over remote authentication server accounts. This means that if a user account exists both locally and on a remote server like TACACS, RADIUS, or LDAP, the local account settings will take priority (D).
