2 passwd passwd Changes the password for the specified user. Synopsis passwd ["user account"] Description Use this command to change a user account password. Operands When this command is invoked without operand, the password is changed for the current login account. The following operand is optional: "user account" Changes the password for the specified user account. The user account must be enclosed in quotation marks, The user account must be an existing account, either default or user-created. Only users with accounts of type "root", "factory" "SecurityAdmin", or "admin" can execute this operand and have permission to change passwords for accounts other than their own. Notes Passwords can be changed locally on any switch. For the password database to be distributed to other switches in the fabric, the switches must be configured to accept the password database with the fddCfg command. The password database is distributed manually with the distribute command. The execution of this command is subject to Admin Domain restrictions that may be in place. If RADIUS authentication is enabled, password change is blocked for users changing their own password. Administrators with the privilege to change passwords for other accounts may do so regardless of whether RADIUS authentication is enabled; all such password changes operate on the local password database. The passwd command cannot be run on the Standby CP. When an admin account or a securityAdmin account changes password for other accounts, it does not prompt for the current password, unless the target account is factory or root account. Any chosen password must satisfy the following password strength rules: • Password contains the minimum required number of lowercase characters • Password contains the minimum required number of uppercase characters • Password contains the minimum required number of numeric characters • Password contains the minimum required number of punctuation characters • Password must be between minlength and 40 characters long • Password may not contain the colon ":" character • Password must satisfy repeated and sequential character constraints The password history policy is enforced across all user accounts when the user is setting his own password. The password history policy is not enforced when an administrator sets a password for another user, but the user's password history is preserved and the password set by the administrator is recorded in the user's password history. The passwd command behaves as follows: • If you are changing your own password, you are prompted to enter the old password and, if your entry is valid, you are prompted to enter the new password. 366 Fabric OS Command Reference 53-1000599-01
