PodWiki supports basic authentication using cookies, which are expiring after one day.
Each page can be protected separately for either reading and/or writing. Permissions can be granted to one or more groups of users or to one single user.
Each user can be a member of one or more groups.
The administrator can configure users and groups from the SiteAdmin page which appears if you are logged in as root.
Users can also register themselfes from the login page.
Passwords are stored in encrypted form. So, if a user forgets his password, you (root) have to change/reset it.
The user can also change his own password if he knows the current password.
You can protect a page for writing which makes it possible to have read-only pages. In this case just add an options block of the following form to the page to be protected:
=begin options write = sales, orderadmin =end
In this example members of the groups 'sales' and 'orderadmin' are able to modify the page in question.
You can also write protect a page for a single user:
=begin options write = user:max =end
This allows the user 'max' to write the page only.
You can also restrict read access to a page, which makes it possible to have "private" pages which are not visible to the public.
You can configure this using this example:
=begin options read = noc, support =end
In this case the protected page is only visible by 'noc' and 'support' members.
You can also read protect a page for a single user:
=begin options read = user:max =end
This allows the user 'max' to read the page only.
PodWiki can be configured to run in a read-only mode. Thus it only displays the content, it does not provide links to edit pages, no upload boxes and stuff. You can do this by setting the read_only variable in the config to yes.
In addition you can define a number of users who have the right to override this setting by configuring 'read_only_override_users', you can add there one or more users separated by comma. If a user listed there logs in, he will get the usual controls to maintain the site, such as the edit bar, or upload links and stuff. Any other user will not get this.
