Configuring Selective Auto-Login for Specific Portals in DNN

Information

To configure selective auto-login for specific portals in your DNN instance, follow these steps:

1. Active Directory Authentication Setup:
   • For each portal where you want to enable auto-login:
     1. Go to the specific portal's settings.
     2. Navigate to Admin > Extensions > Authentication Systems.
     3. Find and edit the "DNN_ActiveDirectoryAuthentication" provider.
     4. Ensure the "Enabled?" checkbox is selected for this portal.
     5. Configure the Active Directory settings as needed (Root Domain, Username, Password, etc.).
2. Auto-login IP Address Configuration:
   • In the Active Directory Authentication settings for each portal where you want auto-login:
     1. Find the "Auto-login IP Address" field.
     2. Enter the IP ranges for your internal network. For example:
        • "192.168.1.1-192.168.1.255; 10.0.0.1-10.0.0.255"
     3. This will ensure that only users coming from these IP ranges will be auto-logged in.
3. Verify Network Configuration:
   • Ensure that the IP ranges you've specified accurately represent your internal network. You may need to consult with your network administrator to get the correct ranges.
4. Test and Verify:
   • After configuring each portal:
     1. Clear the DNN cache.
     2. Restart the application pool in IIS.
     3. Test access from both inside and outside your network to ensure it's working as expected.
5. Consider Using Windows Authentication:
   • For internal portals, consider using Windows Authentication instead of or in addition to Active Directory Authentication for a seamless single sign-on experience.

If the built-in options don't provide enough flexibility, you might need to develop a custom authentication provider that can handle more complex auto-login logic based on both portal and IP address.
