Thread:Project:Support desk/forgot password directs to Special:PasswordReset , but results in Permission Error

I am new to mediawiki. Created a private wiki. When I'm logged out, the link for forgotten password leads to the Special:PasswordReset page, but I see the message:

"You do not have permission to edit your private information, for the following reason:

The action you have requested is limited to users in the group: Users."

How can I debug this ? (I see there used to be a permission variable passwordreset that went along with an extension PasswordReset, but according to the extension's page, it's obsolete) Thanks!

{ Resolved: turned out I'd set $wgGroupPermissions['user']['editmyprivateinfo'] = true; instead of $wgGroupPermissions['*']['editmyprivateinfo'] = true; }
