Package TWiki::Users

Singleton object that handles mapping of users to wikinames and vice versa, and user authentication checking.

ClassMethod new ($session,$impl)

Construct the user management object

ObjectMethod finish

Complete processing after the client's HTTP request has been responded to.

ObjectMethod findUser ($name[,$wikiname][,$nocreate]) -> $userObject

• $name - login name or wiki name
• $wikiname - optional, wikiname for created user
• $nocreate - optional, disable creation of user object for user not found

Find the user object corresponding to $name, which may be either a login name or a wiki name. If $name is found (either in the list of login names or the list of wiki names) the corresponding user object is returned. In this case $wikiname is ignored.

If they are not found, and $nocreate is true, then return undef.

If $nocreate is false, then a user object is returned even if the user is not known.

If $nocreate is false, and no $wikiname is given, then the $name is used for both login name and wiki name.

If nocreate is off, then a default user will be created with their wikiname set the same as their login name. This user/wiki name pair can be overridden by a later createUser call when the correct wikiname is known, if necessary.

ObjectMethod createUser ($login,$wikiname) -> $userobject

Create a user, and insert them in the maps (overwriting any current entry). Use this instead of findUser when you want to be sure you are not going to pick up any default user created by findUser. All parameters are required.

ObjectMethod addUserToMapping ($user) -> $topicName

Add a user to the persistant mapping that maps from usernames to wikinames and vice-versa.

ObjectMethod initializeRemoteUser ($remoteUser) -> $loginName

Return value: $remoteUser

Acts as a filter for $remoteUser. If set, $remoteUser is filtered for insecure characters and untainted.

If not user is passed, the remote user defaults to $cfg{DefaultUserLogin} (usually 'guest').

If we got here via an authentication status failure, then the remote user is set to blank, effectively signalling an illegal access.

If no remote user name was passed in, the user defaults to $cfg{DefaultUserLogin}.
