Our company B had merged with company A. The company A running on companyA.com and had hosted Exchange, Sharepoint 2007.
We had move all of the PC on company A to join our domain companyB.com. Their mailbox also hosted on our Exchange server. There is forest trust between our AD and their AD. Every morning staff at company A will log on to PC to our domain companyB. There have no issue about it.
Their file server also had joined to our domain except their sharepoint server. When their staff want to log on their sharepoint, we will launch IE and IE will prompt asking for username and password, they will key username in format companyA\client01
The issue is when opening their sharepoint, the address og sharepoint will be http://companyA.com
, after they log in, a few second later, another box asking for username and password will appear. I had used Mozzila broswer to test the situation. The result is on 1st prompt credential is asking for http://companyA.com
, for 2nd prompt it will asking for https://companyA.com
. On second prompt, either they keyin password or click on cancel, they still able to access their sharepoint as normal.
I also notice that it they access their sharepoint via https://companyA.com
, there will be no second prompting for username and password.
Another thing is, company A had impliment ISA as their internet security and we don't ISA on our side.
