ObjectMethod getMustChangePassword ($cUID) -> $flag

Returns 1 if the $cUID must change the password, else 0. Returns undef if $cUID not found.

ObjectMethod getUserData ($cUID) -> $dataRef

Return a reference to an array of hashes with user data, used to manage users. Each item is a hash with:

  • {name} - name of field, such as "email"
  • {title} - title of field, such as "E-mail"
  • {value} - value of field, such as "jimmy@example.com"
  • {type} - type of field: text, password, checkbox, label
  • {size} - size of field, such as 40
  • {note} - comment note, if any

User management forms can be build dynamically from this data structure. Each password manager may return a different set of fields.

ObjectMethod setUserData ($cUID,$dataRef)

Set the user data of a user. Same array of hashes as getUserData is assumed, although only {name} and {value} are used.

 

ObjectMethod findUserByWikiName ($wikiname) -> listofcUIDsassociatedwiththatwikiname

  • $wikiname - wikiname to look up
Return a list of canonical user names for the users that have this wikiname.

Note: This method was previously (in TWiki 4.2.0) known as getCanonicalUserID. The name was changed to avoid confusion with TWiki::Users::getCanonicalUserID, which has a more generic function. However to support older user mappers, getCanonicalUserID will still be called if login2cUID is not defined.

Package TWiki::UserMapping

This is a virtual base class (a.k.a an interface) for all user mappers. It is not useable as a mapping in TWiki - use the BaseUserMapping for default behaviour.

User mapping is the process by which TWiki maps from a username (a login name) to a display name and back. It is also where groups are maintained.

See TWiki::Users::BaseUserMapping and TWiki::Users::TWikiUserMapping for the default implementations of this interface.

If you want to write a user mapper, you will need to implement the methods described in this class.

User mappings work by mapping both login names and display names to a canonical user id. This user id is composed from a prefix that defines the mapper in use (something like 'BaseUserMapping_' or 'LdapUserMapping_') and a unique user id that the mapper uses to identify the user.

The null prefix is reserver for the TWikiUserMapping for compatibility with old TWiki releases.

Note: in all the following documentation, $user refers to a canonical user id.

PROTECTED ClassMethod new ($session, $mapping_id)

Construct a user mapping object, using the given mapping id.

ObjectMethod finish ()

Break circular references.

ObjectMethod loginTemplateName () -> $templateFile

Allows UserMappings to come with customised login screens - that should preferably only over-ride the UI function

Default is "login"

ObjectMethod supportsRegistration () -> $boolean

Return true if the UserMapper supports registration (ie can create new users)

Default is false

ObjectMethod handlesUser ($cUID,$login,$wikiname) -> $boolean

Called by the TWiki::Users object to determine which loaded mapping to use for a given user (must be fast).

Default is false

ObjectMethod getCanonicalUserID ($login,$dontcheck) -> cUID

Convert a login name to the corresponding canonical user name. The canonical name can be any string of 7-bit alphanumeric and underscore characters, and must correspond 1:1 to the login name. (undef on failure)

(if dontcheck is true, return a cUID for a nonexistant user too - used for registration)

Subclasses must implement this method.

ObjectMethod getLoginName ($cUID) -> login

Converts an internal cUID to that user's login (undef on failure)

Subclasses must implement this method.

ObjectMethod addUser ($login,$wikiname,$password,$emails) -> cUID

Add a user to the persistant mapping that maps from usernames to wikinames and vice-versa, via a canonical user id (cUID).

$login and $wikiname must be acceptable to $TWiki::cfg{NameFilter}. $login must always be specified. $wikiname may be undef, in which case the user mapper should make one up.

This function must return a canonical user id that it uses to uniquely identify the user. This can be the login name, or the wikiname if they are all guaranteed unigue, or some other string consisting only of 7-bit alphanumerics and underscores.

If you fail to create a new user (for eg your Mapper has read only access),

    throw Error::Simple('Failed to add user: '.$error);
where $error is a descriptive string.

Throws an Error::Simple if user adding is not supported (the default).

ObjectMethod removeUser ($user) -> $boolean

Delete the users entry from this mapper. Throws an Error::Simple if user removal is not supported (the default).

ObjectMethod getWikiName ($cUID) -> wikiname

Map a canonical user name to a wikiname.

Returns the $cUID by default.

ObjectMethod userExists ($cUID) -> $boolean

Determine if the user already exists or not. Whether a user exists or not is determined by the password manager.

Subclasses must implement this method.

ObjectMethod eachUser () -> listIteratorofcUIDs

Called from TWiki::Users. See the documentation of the corresponding method in that module for details.

Subclasses must implement this method.

ObjectMethod eachGroupMember ($group) -> TWiki::ListIteratorofcUIDs

Called from TWiki::Users. See the documentation of the corresponding method in that module for details.

Subclasses must implement this method.

ObjectMethod isGroup ($user) -> boolean

Called from TWiki::Users. See the documentation of the corresponding method in that module for details.

Subclasses must implement this method.

ObjectMethod eachGroup () -> ListIteratorofgroupnames

Called from TWiki::Users. See the documentation of the corresponding method in that module for details.

Subclasses must implement this method.

ObjectMethod eachMembership ($cUID) -> ListIteratorofgroupsthisuserisin

Called from TWiki::Users. See the documentation of the corresponding method in that module for details.

Subclasses must implement this method.

ObjectMethod isAdmin ($user) -> $boolean

True if the user is an administrator. Default is false

ObjectMethod isInGroup ($user,$group,$scanning) -> bool

Called from TWiki::Users. See the documentation of the corresponding method in that module for details.

Default is false

ObjectMethod findUserByEmail ($email) -> \@users

  • $email - email address to look up
Return a list of canonical user names for the users that have this email registered with the password manager or the user mapping manager.

Returns an empty list by default.

ObjectMethod getEmails ($user) -> @emailAddress

If this is a user, return their email addresses. If it is a group, return the addresses of everyone in the group.

Duplicates should be removed from the list.

By default, returns the empty list.

ObjectMethod setEmails ($user,@emails)

Set the email address(es) for the given user. Does nothing by default.

ObjectMethod findUserByWikiName ($wikiname) -> listofcUIDsassociatedwiththatwikiname

Called from TWiki::Users. See the documentation of the corresponding method in that module for details.

Subclasses must implement this method.

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

Finds if the password is valid for the given user.

Returns 1 on success, undef on failure.

Default behaviour is to return 1.

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

If the $oldPassU matches matches the user'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.

Default behaviour is to fail.

ObjectMethod passwordError () -> $string

Returns a string indicating the error that happened in the password handlers TODO: these delayed errors should be replaced with Exceptions.

returns undef if no error 9the default)

ObjectMethod ASSERT_IS_CANONICAL_USER_ID ($user_id) -> $boolean

Used for debugging to ensure we are actually passing a canonical_id

ObjectMethod ASSERT_IS_USER_LOGIN_ID ($user_login) -> $boolean

Used for debugging to ensure we are actually passing a user login

ObjectMethod ASSERT_IS_USER_DISPLAY_NAME ($user_display) -> $boolean

Used for debugging to ensure we are actually passing a user display_name (commonly a WikiWord Name)

Returns true by default.
