I am looking to build a SharePoint 2016 website, with custom authentication requirements:
1- External users should be authenticated against AD1 and the site should provide custom registration pages for them with reset password etc.
2- Internal users should be authenticated against AD2 (no registration required as they exist in the comapny's AD)
Moreover, the site should have a professional layout. More details could be obtained after we decided about the developer.
Note: please send me examples of similar requirements that you have implemented before
