39 - [[BulkResetPassword]] if for administrators who want to reset many passwords at once
40 - [[ChangeEmailAddress]] changes the hidden email address stored in the password file
42 ## <a name="Changing User Account Names"></a> Changing User Account Names
44 To change the user's [[WikiName]]:
46 - Rename the user's TWiki homepage in the Main web, such as from `JaneSmith` to `JaneMiller`.
47 - Fix backlinks in the Main web only
48 - Make sure the group topics are updated (if any.)
49 - Edit the [[Main.TWikiUsers|Main/TWikiUsers]] topic and move the user's entry so that the list is in proper alphabetical order.
50 - Recreate the old topic with a pointer to the new topic, so that links in other webs work properly. Example content:%BR% `%M% Jane Smith is now known as JaneMiller`
52 If external authentication is used and you want to change the login name:
54 - The login name needs to be changed in the authentication server (e.g. Active Directory)
55 - In TWiki's [[Main.TWikiUsers|Main/TWikiUsers]] topic, fix the mapping from login name to [[WikiName]]:%BR% ` * JaneSmith - jsmith - 13 Sep 2006` %BR% to: %BR% ` * JaneMiller - jmiller - 13 Sep 2006`
57 ## <a name="Removing User Accounts"></a> Removing User Accounts
59 To remove a user account (FredQuimby, who logs in as "fred"):
61 1. If you are using a `.htpasswd` file, edit the `.htpasswd` file to delete the line starting `fred:`
62 - **Warning:** Do **not** use the Apache `htpasswd` program with `.htpasswd` files generated by TWiki! `htpasswd` wipes out email addresses that TWiki plants in the info fields of this file.
63 2. Remove the `FredQuimby - fred` line from the Main.TWikiUsers topic
64 3. Remove `FredQuimby` from all groups and from all the `ALLOWWEB/ALLOWTOPIC...` declarations, if any.%BR% **_Note:_** If you fail to do this you risk creating a security hole, as the next user to register with the wikiname FredQuimby will inherit the old FredQuimby's permissions.
65 4. _[optional]_ Delete their user topic Main.FredQuimby (including attachments, if any.)
67 **_Note:_** Consider leaving the user topic file in place so their past signatures and revision author entries don't end up looking like [[AnUncreatedTopic]]. If you want to make it clear the user is no longer around, replace the topic content with a note to that effect. The existance of the UserName topic should also prevent that user name from being re-used, sealing the potential security hole regarding inherited permissions..
