Cannot Get More SSO Users

Denny Chanditya Posted 28 Aug 2023 13:38

Hi,

We have several IAG 5000 series, that setup with the SSO / MS AD Domain so the Sangfor can get username for the IP, rather than only the IP Address.
Our issue is the IAG only read several users with username on the tab Users, we was check the connectivity is OK, ask the principal and use the Mirror interface for read users list but it still cannot work properly. only few users are show

is there any troubleshooting or any test that i need to do? on other IAG was works normally it can read the users from AD.

Thanks.

Troubleshooting the issue of the Sangfor IAG 5000 series not properly retrieving usernames from the Active Directory (AD) for some users can involve several steps to identify and resolve the problem. Here's a systematic approach to help troubleshoot the issue:
  • Review Configuration: Double-check the configuration settings on the IAG 5000 series that is experiencing the issue. Compare it with the configurations of the IAG units that are working correctly. Ensure that the settings related to SSO and AD integration are consistent.
  • Verify Connectivity: Ensure that the IAG unit can properly communicate with the Active Directory. Test the connectivity by pinging the domain controllers and ensuring that DNS resolution is working correctly.
  • Check AD Integration: Review the integration between the IAG unit and the Active Directory. Verify that the LDAP configuration settings, including the domain name, domain controllers, and authentication credentials, are accurate.
  • Check for LDAP Issues: Monitor the IAG's logs or diagnostic information for any LDAP-related errors or warnings. LDAP authentication issues could potentially prevent the retrieval of usernames.
  • Check User Attributes: Confirm that the users for whom usernames are not being retrieved have the necessary attributes in the Active Directory. The IAG might rely on specific attributes to identify users.
  • Test with Different Users: Experiment with different user accounts to determine if the issue is specific to certain users or applies to a broader range. This can help narrow down whether it's a configuration problem or an issue with particular user accounts.
  • Check for Account Lockouts or Expiry: Verify that the affected user accounts are not locked out or expired in the Active Directory. Account status issues could prevent successful authentication.
  • Mirror Interface Configuration: Since you've mentioned using the Mirror interface, ensure that it's properly configured to capture the necessary traffic. Check for any limitations or settings that might impact the traffic monitoring process.
  • Test Different Interfaces: If possible, test using different interfaces to retrieve user information. This can help identify whether the issue is specific to the Mirror interface or is more widespread.
  • Update or Firmware Check: Ensure that the IAG unit is running the latest firmware or software updates. Sometimes, updates can address known issues or improve compatibility.

When you're experiencing issues with an IAG (Internet Access Gateway) appliance not properly retrieving user information from Active Directory (AD) for Single Sign-On (SSO), there could be several reasons behind it. Troubleshooting this issue may involve checking various aspects of your configuration and network environment. Here are some troubleshooting steps and tests to perform:

Check Active Directory Integration:
Ensure that your IAG appliance is properly integrated with your Active Directory domain. This includes verifying that the configuration settings for AD integration are correct, such as the domain name, LDAP server details, and user search base.

User Permissions:
Ensure that the IAG appliance has the necessary permissions to query the Active Directory. The service account or credentials used for AD integration should have read access to the necessary AD attributes for user identification.

Check User Accounts:
Review the user accounts in Active Directory. Ensure that the users who are not appearing in the IAG's user list have their accounts and attributes properly configured in AD, including the attribute that the IAG uses for identifying users.

LDAP Connectivity Test:
Use a tool like ldapsearch or a similar LDAP testing tool to verify that the IAG appliance can successfully connect to and query the Active Directory server. Test the LDAP connectivity using the same settings as configured in the IAG.

Example LDAP test command:

ldapsearch -x -H ldap://your_ad_server -b "ou=Users,dc=example,dc=com" -D "cn=admin,dc=example,dc=com" -W
Replace the placeholders with your actual LDAP server details.

Logging and Debugging:
Enable and review logs on the IAG appliance for any error messages or clues about the issue. Look for logs related to the AD integration and user identification process. Increasing the logging level may provide more detailed information.

Firewall and Network Configuration:
Verify that there are no firewall rules or network issues that might be blocking or disrupting communication between the IAG appliance and the Active Directory server.

Mirror Interfaces:
Ensure that the IAG appliance is properly configured to mirror traffic to the interfaces where AD authentication is taking place. Sometimes, not mirroring the correct interface can lead to user identification issues.

Software Updates:
Check if there are any firmware or software updates available for your IAG appliance. Updating to the latest version may resolve known issues or bugs.

Compare Configurations:
Compare the configuration of the problematic IAG appliance with those of the working ones. Ensure that there are no discrepancies or missing settings.

Contact Vendor Support:
If the issue persists and you've exhausted your troubleshooting efforts, consider reaching out to Sangfor's support or the vendor's support for assistance. They may have specific knowledge and tools to diagnose and resolve the issue.

When you're facing issues with Sangfor IAG (Internet Access Gateway) not properly retrieving user information from Microsoft Active Directory (AD) for Single Sign-On (SSO), there are several troubleshooting steps and tests you can perform to diagnose and potentially resolve the problem. Here's a step-by-step approach to address this issue:

    Check Network Connectivity:
        Verify that the Sangfor IAG appliance has proper network connectivity to the Active Directory server. Ensure DNS resolution is working correctly.

    Review Configuration:
        Double-check the configuration settings on the Sangfor IAG:
            Ensure that the AD integration settings are correctly configured, including the LDAP server information.
            Verify that the AD integration account used by Sangfor IAG has the necessary permissions to query AD for user information.
            Check for any errors or misconfigurations in the Sangfor IAG settings related to SSO and AD integration.

    Test LDAP Connectivity:
        Use a tool like ldapsearch or ldp.exe to manually test the LDAP connectivity from the Sangfor IAG appliance to the AD server. This will help ensure that the Sangfor IAG can reach the AD server and query user information.

    Check User Permissions:
