How to Fix Error 24495 on Cisco Secure Access Control System

Cisco Secure Access Control System (ACS) is a software solution that provides authentication, authorization, and accounting (AAA) services for network devices and users. ACS can integrate with various identity sources, such as Active Directory, LDAP, or internal databases, to verify the credentials of users and devices that access the network.

However, sometimes ACS may encounter errors when communicating with the identity sources, such as error 24495. This error indicates that the Active Directory servers are not available or reachable by ACS. This can cause authentication failures or delays for users and devices that rely on Active Directory for authorization.

In this article, we will explain what causes error 24495 and how to troubleshoot and resolve it.

What Causes Error 24495?

Error 24495 can occur due to various reasons, such as:

  • Network connectivity issues between ACS and Active Directory servers
  • Incorrect configuration of ACS or Active Directory settings
  • Expired or invalid certificates or credentials for ACS or Active Directory
  • Firewall or antivirus blocking the communication between ACS and Active Directory
  • Corrupted or outdated ACS software or database

How to Troubleshoot Error 24495?


What Causes Error 24495?

To troubleshoot error 24495, you can follow these steps:

  1. Check the network connectivity between ACS and Active Directory servers. You can use ping, traceroute, or telnet commands to test the reachability and latency of the servers. You can also check the status of the network interfaces and cables on both ends.
  2. Check the configuration of ACS and Active Directory settings. You can verify that the ACS has the correct IP address, hostname, port number, domain name, and join point for the Active Directory servers. You can also check that the Active Directory servers have the correct DNS records, service principal names (SPNs), and permissions for the ACS.
  3. Check the certificates and credentials for ACS and Active Directory. You can ensure that the ACS has a valid certificate from a trusted certificate authority (CA) and that it matches the hostname of the ACS. You can also ensure that the ACS has a valid account and password for joining the Active Directory domain and that it has not expired or changed.
  4. Check the firewall and antivirus settings on both ACS and Active Directory servers. You can verify that the firewall and antivirus are not blocking the ports or protocols used by ACS and Active Directory for communication. You can also check the logs of the firewall and antivirus for any errors or warnings related to ACS or Active Directory.
  5. Check the ACS software and database. You can verify that the ACS software is up to date and that it does not have any bugs or vulnerabilities that could affect its functionality. You can also check that the ACS database is not corrupted or full and that it has enough space and resources to operate.
