    2. Portallogin.html - This is the alternative portal login page when NTLM Authentication fails.
    3. Logout.html - This is the portal logout page when using NTLM Authentication.

  • Third-Party files

    1. Msxml3.dll - This is the Microsoft XML Parser version 3.0 w/sp1.

    • IV. Basic Configuration

    1. Local.properties file

      1. Located in [Portal_Install_Dir]/properties/local.properties
      2. Modify the login.impl variable to reflect the example below:
        login.impl=com.ca.portal.base.util.NTLMLogin
      3. Add the login.href variable:
        login.href=http://[IIS Server Name]/[Virtual Directory]/portallogin.asp
      4. Add the logout.href variable:
        logout.href=http://[IIS Server Name]/[Virtual Directory]/logout.html

  • Edit the portallogin.asp file. Please view the file in a text editor for details

    1. Make sure that the admin password that is defined in this file is correct. By default the admin password is admin, and this is what is used as an example in this file. If the admin password has been changed, make sure that it is reflected correctly in the portallogin.asp file.

    2. Under the commented out heading ''Native Login UI URL when not using NT authentication" please change the NativeLoginURL to the actual name of your IIS server.

      NativeLoginURL = http://[IIS Server Name]/portal/portallogin.html

    3. pecify your domain for Domain = array("")
      Ex. Domain = array("DOMAIN1","DOMAIN2","DOMAIN3")

  • Edit the portallogin.html file

    1. Modify the [portalserver_name] variable to point to the running Portal server. Example:
      http://[portalserver_name]:8080/servlet/portal

  • Edit the logout.html file

    1. Modify the [portalserver_name] variable to point to the running Portal server. Example:
      http://[portalserver_name]:8080/servlet/portal

    • V. Advanced Configuration

    1. Adding Multiple Domains to Authenticate Against

      1. Edit the Domain variable in the portallogin.asp file. Example: Domain="abc|xyz|aaa
      2. The domains you add have to either be trusted or you have to change the file permissions on the portallogin.asp file to include the "Authenticated Users" group from each domain you want to authenticate against. Again, this is not necessary if the domains trust each other.

  • Using NTLM and LDAP Simultaneously

    1. In order to use LDAP and NTLM together, you must make the following changes to the portallogin.asp file:
      1. Build User = False
      2. RemoveDomain = True
      3. Password = Your LDAP Server Password (This is normally ?LDAP# - where # is the number of your LDAP server.)
