---+ Package =TWiki::Users::BaseUserMapping=

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.

The BaseMapper provides support for a small number of predefined users.
No registration - this is a read only usermapper. It uses the mapper
prefix 'BaseUserMapping_'.

---++ Users
   * TWikiAdmin - uses the password that was set in Configure (IF its not null)
   * TWikiGuest
   * UnknownUser
   * TWikiContributor - 1 Jan 2005
   * TWikiRegistrationAgent - 1 Jan 2005

---+++ Groups
   * $TWiki::cfg{SuperAdminGroup}
   * TWikiBaseGroup


%TOC%

---++ ClassMethod *new* <tt>($session)</tt>

Construct the BaseUserMapping object



---++ ObjectMethod *finish* <tt>()</tt>
Break circular references.



---++ ObjectMethod *loginTemplateName* <tt>() -> templateFile</tt>

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



---++ ObjectMethod *handlesUser* <tt>($cUID,$login,$wikiname) -> $boolean</tt>

See baseclass for documentation.

In the BaseUserMapping case, we know all
the details of the users we specialise in.



---++ ObjectMethod *login2cUID* <tt>($login) -> $cUID</tt>

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)



---++ ObjectMethod *getLoginName* <tt>($cUID) -> login</tt>

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



---++ ObjectMethod *getWikiName* <tt>($cUID) -> wikiname</tt>

Map a canonical user name to a wikiname



---++ ObjectMethod *userExists* <tt>($user) -> $boolean</tt>

Determine if the user already exists or not.



---++ ObjectMethod *eachUser* <tt>() -> listIteratorofcUIDs</tt>

See baseclass for documentation.



---++ ObjectMethod *eachGroupMember* <tt>($group) -> listIteratorofcUIDs</tt>

See baseclass for documentation.

The basemapper implementation assumes that there are no nested groups in the
basemapper.



---++ ObjectMethod *isGroup* <tt>($name) -> boolean</tt>

See baseclass for documentation.



---++ ObjectMethod *eachGroup* <tt>() -> ListIteratorofgroupnames</tt>

See baseclass for documentation.



---++ ObjectMethod *eachMembership* <tt>($cUID) -> ListIteratorofgroupsthisuserisin</tt>

See baseclass for documentation.



---++ ObjectMethod *isAdmin* <tt>($cUID) -> $boolean</tt>

True if the user is an admin
   * is a member of the $TWiki::cfg{SuperAdminGroup}



---++ ObjectMethod *getEmails* <tt>($name) -> @emailAddress</tt>

If $name is a cUID, return their email addresses. If it is a group,
return the addresses of everyone in the group.



---++ ObjectMethod *findUserByWikiName* <tt>($wikiname) -> listofcUIDsassociatedwiththatwikiname</tt>

See baseclass for documentation.



---++ ObjectMethod *checkPassword* <tt>($login,$passwordU) -> $boolean</tt>

Finds if the password is valid for the given user.

Returns 1 on success, undef on failure.



---++ ObjectMethod *setPassword* <tt>($cUID,$newPassU,$oldPassU) -> $boolean</tt>

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.



---++ ObjectMethod *passwordError* <tt>() -> $string</tt>

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

returns undef if no error
