Ate Douma commented on JS2-151:
-------------------------------

Task 9) will be implemented now with JS2-27, together with JS2-21 and thus will no longer depend on JS2-241.
And because the other tasks are already done, I will close this issue.

> As proposed on the list (see: http://nagoya.apache.org/eyebrowse/ReadMsg?listId=22&msgNo=18415 )
> several security enhancements will be implemented:
> Allow:
> 1) storing password encoded (initially using Base64)
> 2) requiring a minimum length and a minimum number of numeric characters in a password
> 3) keeping a history (queue) of previously used password and preventing a user to reuse one from this queue (with a configurale queue size)
> 4) automatically expire password after a configurable time
> 5) warning a user its password is going to be expired (with a configurable time before)
> 6) locking a user out when the current password is expired
> 7) forcing a user to change a password on first use
> 8) disable a password after a certain number of failures to authenticate, reset check after success
> 9) enable/disable principals: users,groups,roles (see also earlier  and never implemented issue http://issues.apache.org/jira/browse/JS2-27 )
> This will be implemented using the the following enhancements:
> - boolean enabled attribute for principals and credentials
>   false: principal/credential is *never* used in security checks, meaning:
>      - user cannot log in if its user principal is disabled
>          - user cannot log in if no credential is enabled
>          - disabled groups or roles will not be added to a subject
>          Usage for administrative purposes in *not* to be limited by this:
>          A administrator can still assign disabled groups/roles to a user/group/role or whatever.
>          They just won't have any effect *yet*.
> - int authentication failures attribute on PasswordCredential (0 as default or for other type of credentials):
>   -1 means never tried yet (to indicate enforce change password on first use)
>   0 means none or last time was successful
>   > 0 number of failures (to allow disable after configurable failures)
> - boolean valid attribute on PasswordCredential (default = true, or only false if null/empty):
>   Allows for password sanity check before even trying to authenticate or set/change a password.
>   A specific PasswordCredential implementation (see next feature) then could check against above mentioned rules like minimum length,
>   number of numeric characters, a regular expression, etc.
> - Define a PasswordCredentialComponent/Provider/Factory to allow specialized versions of PasswordCredential to be used
>   as describe above, instead of the current implementations which does hardcoded PasswordCredential instantiations.
> - Date expiration date attribute on PasswordCredential indicating the lifespan of a password,
>   null in the default implementation indicating never
> - boolean expired attribute indicating on PasswordCredential, default false:
>   true: non-valid PasswordCredential because a newer PasswordCredential is defined or the lifespan had ended.
> - An enhanced CredentialHandler enforcing most of my above requirements, configurable through the jetspeed-spring.xml
>   with parameters like: password history size, password expiration time and max authentication failures.
> - A new pipeline security value (in addition to the current one) which checks on a authenticated user (Subject)
>   - if a password change is required: force the user to a change password page/portlet
>   - if a password is about to be expired: inject some sort of warning message into the aggregated output
>     (I don't have clue yet how to do that, probably some kind of javascript message, maybe need an additional valve for that)
> The above implementations will initially only be available as system wide features, not (yet?) per user, group or role.
