Add information about openid requirements to /admin/info
Issue #3431 asked for information about the installed openid requirements. Resolution was to add some documentation.
For an admins trying to enable openid authentication (like myself) it is however not initially clear that a further dependency (i.e. the
ruby-openid gem) is necessary. Therefore I propose a patch to add the information about the (not) installed gem to
The most informative patch however would be a short notice just below the checkbox stating in 3 words that the
ruby-openid could not be found. Thus the admin wuould not be forced to search for hints on why the checkbox might be disabled.
