The behavior is intentional - but can be configured. Since the index-page contains often content that an admin wants to control, admin permissions are required per-default for editing the index page.
Background: The standard permission policy of an xowiki instance is policy1, which is defined as follows (in xowiki/tcl/package-procs-tcl)
Policy policy1 -contains {
...
Class Page -array set require_permission {
view none
revisions {{package_id write}}
diff {{package_id write}}
edit {
{{regexp {name {(weblog|index)$}}} package_id admin}
{package_id write}
}
...
This means, that for objects of class Page (i.e. all kind of xowiki pages)
edit operations are allowed under the following premises:
- when the name of the page ends with weblog or index, the user has to have admin rights on the package_id
- otherwise, the user has to have write permissions on the package_id.
This is exactly. what you observe.
One can modify this policy by editing package-procs.tcl, or one can use one of the other predefined policies, or one add site-specific policies (e.g. in a separate file) and configure it in the package parameters...
all the best
