Can't get SSO with NTLM to work

Hi!

Im using Adobe Connect 9.1.1, and I have followed the instructions to activate SSO with NTLM in the installation guide:

* Synched user-accounts with my AD, by using LDAP

* Changed login policy to use account-name instead of email

* Changed authentication mode to use LDAP-authentication

* Added NTLM_DOMAIN=mydomain (tried normal name, windows 2000 name, etc), to "9.1.1\Custom.ini"

* Added NTLM_SERVER=IP of my AD-server, to "9.1.1\Custom.ini"

* Modified appserv\web\WEB-INF\web.xml, so I have uncommented NTLM-section and commented out Header-section

* Restarted "Central Application"-service and "Meeting"-service

It works if I manually log in with my AD user/password on the normal Adobe Connect login-page. But SSO wont work.

If I log on to the server with my AD-account and open Internet Explorer and go to the login-page, It first shows the Windows standard "Login to domain" popup. I type in my correct account-name and password, but then I get redirected to the normal Adobe Connect Login-page .

I only see "NO_ACCESS_NO_LOGIN" in the "logs\access.log"

My Adobe Connect services are installed on a Windows 2008 R2 Server, and my AD is installed on a WIndows Server 2012. Could that be a problem?

Any help appreciated!

thanks.
