HELP Intranet Access using AD user Account matching ADLDS User Proxy


I'm working on a project which consist of accessing Intranet with Active directory user account which matches ADLDS UserProxy object.

Project Description

1- The goal is ADLDS will hold unique users comming from different forest after it's been provisionned by FIM 2010.

2- Users will keep there Login and access Intranet without the  need to  use there credential
After they log on they just have to click  Internet Explorer and  taaaddddaaaa!!!!


1- FIM provision ADLDS with UserProxy accounts with a cn that  looks like <Firstname>.Lastname> example: Jhon.cooper

2- Jhon AD Samaccount looks like <First letter of the first name><Lastname> Example: jcooper

3- jhon UserProxy object is bind to his AD account


1 - When Jhon authenticate to AD with his AD account (jcooper) he can not acces the intranet

2 - When i create  an AD user account for jhon with the login that's looks like <Jhon.cooper> (Same as the UserProxy object cn in ADLDS)
Jhon can acces Intranet successfully!!!!!

3 - Obviousely Jhon can't autheticate on AD with his ADLDS cn (This is normal) and the goal is the user keep there actual AD login to access Intranet


I don't understand why with formal user AD account they can't access Intranet but when recreating another user account which match the ADLDS userproxy cn it works fine ????

NB: For testing reason we've exported all AD forest from Production environment in to a testing lab environment.

Thank You

probably the intranet application is checking on the wrong field.... is there some way you can log the query result in the application (i mean: there should be a part of the code looking for userproxy field, querying AD)

Another option is that FIM doesn't provision the userproxy field correctly...

as per read here, userproxy should be the "linkage" betw ADLDS and AD...
