Difference: TWikiUsersPasswordDotPm (3 vs. 4)

Revision 42008-01-22 - TWikiContributor

 

Package =TWiki::Users::Password

Base class of all password handlers. Default behaviour is no passwords, so anyone can be anyone they like.

The methods of this class should be overridded by subclasses that want to implement other password handling methods.

ClassMethod new ($session) -> $object

Constructs a new password handler of this type, referring to $session for any required TWiki services.

Changed:

ObjectMethod *finish

ObjectMethod finish ()

Added:

>
Break circular references.
 
Deleted:
<
<
Complete processing after the client's HTTP request has been responded to.
  1. breaking circular references to allow garbage collection in persistent environments
 
Added:

ObjectMethod readOnly () -> boolean

 
Added:

returns true if the password database is not currently modifyable also needs to call $this->{session}->enter_context('passwords_modifyable'); if you want to be able to use the existing TWikiUserMappingContrib ChangePassword topics

 

ObjectMethod fetchPass ($login) -> $passwordE

Implements TWiki::Password

Changed:
<
<
Returns encrypted password if succeeds. Returns 0 if login is invalid.
>
>
Returns encrypted password if succeeds.
Added:

>
Returns 0 if login is invalid.
 Returns undef otherwise.

Changed:
<

ObjectMethod checkPassword ($user,$passwordU) -> $boolean

>
>

ObjectMethod checkPassword ($login,$passwordU) -> $boolean

 
Changed:
<
<
Finds if the password is valid for the given login.
>
>
Finds if the password is valid for the given user.
  Returns 1 on success, undef on failure.

Changed:

ObjectMethod deleteUser ($user) -> $boolean

ObjectMethod removeUser ($login) -> $boolean

 
Changed:
<
<
Delete users entry.
>
>
Delete the users entry.
 
Deleted:
<
<
Returns 1 on success, undef on failure.

ObjectMethod setPassword ($login,$newPassU,$oldPassU) -> $boolean

 
Changed:
<
<

ObjectMethod passwd ($user,$newPassU,$oldPassU) -> $boolean

>
>
If the $oldPassU matches matches the user's password, then it will
Deleted:
<
<
If the $oldPassU is undef, it will try to add the user, failing if they are already there.

If the $oldPassU matches matches the login's password, then it will

 replace it with $newPassU.

If $oldPassU is not correct and not 1, will return 0.

If $oldPassU is 1, will force the change irrespective of the existing password, adding the user if necessary.

Otherwise returns 1 on success, undef on failure.

Changed:
<
<

encrypt( $user, $passwordU, $fresh ) -> $passwordE

>
>

encrypt( $login, $passwordU, $fresh ) -> $passwordE

  Will return an encrypted password. Repeated calls
Changed:
<
<
to encrypt with the same user/passU will return the same passE.
>
>
to encrypt with the same login/passU will return the same passE.
  However if the passU is changed, and subsequently changed back
Changed:
<
<
to the old user/passU pair, then the old passE is no longer valid.
>
>
to the old login/passU pair, then the old passE is no longer valid.
  If $fresh is true, then a new password not based on any pre-existing salt will be used. Set this if you are generating a completely new password.

ObjectMethod error () -> $string

Return any error raised by the last method call, or undef if the last method call succeeded.

Changed:
<
<

ObjectMethod getEmails ($user) -> @emails

>
>

ObjectMethod *isManagingEmails () -> $boolean

Added:
>
>
Determines if this manager can store and retrieve emails. The password manager is used in preference to the user mapping manager for storing emails, on the basis that emails need to be secure, and the password database is the most secure place. If a password manager does not manage emails, then TWiki will fall back to using the user mapping manager (which by default will store emails in user topics)
 
Changed:
<
<
Fetch the email address(es) for the given username. Default behaviour
>
>
The default ('none') password manager does not manage emails.
Deleted:
<
<
is to look up the users' personal topic.
 
Changed:
<
<

ObjectMethod setEmails ($user,@emails)

>
>

ObjectMethod getEmails ($login) -> @emails

Added:
>
>
Fetch the email address(es) for the given login. Default behaviour is to return an empty list. Called by Users.pm. Only used if isManagingEmails -> true.
 
Changed:
<
<
Set the email address(es) for the given username in the user topic.

ObjectMethod setEmails ($login,@emails) -> $boolean

Set the email address(es) for the given login name. Returns true if the emails were set successfully. Default behaviour is a nop, which will result in the user mapping manager taking over. Called by Users.pm. Only used if isManagingEmails -> true.

ObjectMethod *findLoginByEmail ($email) -> \@users

Returns an array of login names that relate to a email address. Defaut behaviour is a nop, which will result in the user mapping manager being asked for its opinion. If subclass implementations return a value for this, then the user mapping manager will not be asked. Only used if isManagingEmails -> true.

Called by Users.pm.

ObjectMethod canFetchUsers () -> boolean

returns true if the fetchUsers method is implemented and can return an iterator of users. returns undef / nothing in this case, as we are unable to generate a list of users

ObjectMethod fetchUsers () -> newTWiki::ListIterator(\@users)

returns a TWikiIterator of loginnames from the password source. If AllowLoginNames is false this is used to remove the need for a TWikiUsers topic.
