<adm:synopsis>
|
The
|
<adm:user-friendly-name />
|
determines whether a proposed password is acceptable by measuring
|
how similar it is to the user's current password.
|
</adm:synopsis>
|
<adm:description>
|
In particular,
|
it uses the Levenshtein Distance algorithm to determine the
|
minimum number of changes (where a change may be inserting,
|
deleting, or replacing a character) to transform one string into
|
the other. It can be used to prevent users from making only minor
|
changes to their current password when setting a new password.
|
Note that for this password validator to be effective, it is
|
necessary to have access to the user's current password.
|
Therefore, if this password validator is to be enabled, the
|
password-change-requires-current-password attribute in the
|
password policy configuration must also be set to true.
