Here in this SharePoint 2016 tutorial we will discuss about what is an alternate access mapping in SharePoint 2016? How we can configure alternate access mapping?
What is Alternate Access Mapping (AAM)?
Alternate Access mappings in SharePoint allows you to create multiple URLs for the same web application. This will helps users from the internal company networks users to access intranet site by simply using http / https URL and forcing outside the network users accessing it from the internet to use the fully-qualified domain name.
Note: Alternate Access
Internal users: http://contoso.com
External users: http://intranet.contoso.com
There are 2 type of Alternate Access Mappings can be configured in SharePoint 2016 they are:
1. Internal URLs
2. Public URLs
We could say Internal URL is simply an alias for the same site. Which means when users type this URL in browser SharePoint redirects them to Public URL of this Web Application.
This is the other URL configured/mapped to the SharePoint Web Application. This URL completely looks different than the actual URL of the Web Application. However, this URL will be pointed/linked to the same Web Application.
1. User requested SharePoint site and it must be resolved in DNS fist and then it will routed back to load balancer (or) SharePoint Web Front End Server (SP-WFE)
2. IN WFE, IIS will receive the request and look for an IIS binding or an IIS Site
3. Once IIS matches the one of the Sites then the request will go to SharePoint and render the SharePoint site to user
Note: The load balancer can any this like F5 / NetScaler / Kemp etc
Please follow the below 3 key points white working with Alternate Access Mappings
- Alternate Access Mappings managed from Central admin will affect only in SharePoint alone.
- Changing an Alternate Access Mapping does not make any changes in DNS or IIS
- Whenever a new URL to be mapped to a Web Application nor edit the existed should be implemented in 3 different places:
1. DNS (Domain Name Server)
Create and Configure Alternate Access Mapping:
1. Log-on to Application server with FARM administrator account
2. Central Administration -> Configure alternate access mappings
3. It will take you to next page and you will be able to add / edit the Alternate Access Mappings
4. Click on “Add Internal URLs”
5. As soon as you create the Alternate Access Mapping you need to ensure that same has been added to DNS. It can be done by only IT.
6. After adding the DNS entry you need do the mapping in IIS also.
Steps to be followed:
– Open Internet Information Services
– Expand Sites and select the required web application
– Click on the bindings under Actions
– Click on add on Add on the popup
– Enter the URL and click on OK.
7. Open the URL in IE
