ADAM setup for AD .net memebership provider

I have been working on a project lately called RAI. I am not going to talk about it here, but basically it is an external facing and internal facing application for one of the organisations I provide IT services for. For the external client we decided to use ADAM for the authentication source, so I started to have a look at using ADAM and the AD membership provider. Well lets just say that was 5 days I will never get back. So just in case you are ever in a situation where you need to get the AD membership provider to work with ADAM these are the step to installing ADAM so it is setup ready for you.


ADAM can be downloaded from Microsoft at
http://www.microsoft.com/downloads/details.aspx?FamilyId=9688F8B9-1034-4EF6-A3E5-2A2A57B5C8E4&displaylang=en#filelist

The following steps are required to install ADAM for use with the Active Directory .Net membership provider.




1. Run the ADAM installer.
2. Select “unique instance” , press next
3. Set the instance name to your project name in this case I am using “RAI” , press next
4. Set the LDAP port to 50000 and the SSL port to 50001 ,press next
5. Select “Yes, Create an application directory partition” and set the partition name to “O=[projectname]” , again in this case I use RAI press next.
6. Accept default or select a suitable place for the files , press next
7. Choose default for Service Account Selection
8. Choose "Currently logged on account" for ADAM Adminstrators
9. Import "MS-InetOrgPerson", "MS-User" and "MS-Userproxy"
10. Click next to complete the install
The ADAM instance for RAI will now be installed on the application server. It must now be configured.


11. Open "ADAM ADSI Edit" from the ADAM program group in your start menu
12. Select "Action->Connect to..."
13. For name use your projectname
14. Alter the correct portnumber in the Port textbox (50000)
15. Change to “Well-Known naming context” and select “Schema” and then press OK



16. Right click on the schema item and select new object. From the class menu select “AttributeSchema”.
17. Create the following 5 new attribute schema entries

cn: PwdQuestion

18. Close the "ADAM ADSIedit" program
19. The user schema object in the ADAM instance needs to be modified to support the additional attributes created in step 17. This needs to be done via the mmc ADAM snap-in. To create an MMC file for the ADAM Schema snap-in

You will obviously need to setup your application web.config to use this ADAM instance. Have a look at http://authors.aspalliance.com/aspxtreme/sys/web/security/ActiveDirectoryMembershipProviderClass.aspx and http://msdn2.microsoft.com/en-us/library/ms998360.aspx for this information.
