When viewing the htpasswrd on the IDP page, at the bottom of the list of users, there will be a link to "View all users ( x )" where "x" is the total number of users if the user is an admin and has the feature gate enabled. This link will go to a htpasswrd IDP details page.

If the user is not an admin or has the feature gate enabled then "( x more )" text will be at the bottom of the user list where "x" is the number of users beyond the 5 shown. (Current behavior)

Note: this was spun off from OCMUI-2966
