Password Validation
Note
Password validation options apply only to user passwords stored in the 
CiscoSecure user database. They do not apply to passwords in user records 
kept in external user databases nor do they apply to enable or admin passwords 
for Cisco IOS network devices.
Setting Password Validation Options
The password validation options are listed below:
Password length between X and Y characters—Enforces that password 
lengths be between the values specified in the X and Y boxes, inclusive. 
Cisco Secure ACS supports passwords up to 32 characters in length.
Password may not contain the username—Requires that a user password 
does not contain the username anywhere within it.
Password is different from the previous value—Requires a user’s new 
password to be different from the previous password.
Password must be alphanumeric—Requires a user password to contain 
both letters and numbers.
