When you create a method with the Advanced Authentication Generic class, the Advanced Authentication Chains field displays No Chains Configured and does not display the list of all the configured chains. This issue occurs after upgrading Access Manager from 4.3.3 or earlier supported versions to 4.4 or later.
To workaround this issue, recreate the endpoints.
Recreating the endpoints
Delete the existing endpoint from the Advanced Authentication server.
On the Access Manager Administration Console, click Devices > Identity Servers > Shared Settings > Advanced Authentication
In the Server Domain field, change the IP address of the Advanced Authentication server to a dummy IP address.
For example, if the original IP address of Advanced Authentication server is 164.99.185.123, then change it to a dummy IP address such as, 164.99.184.321.
Verify if the same dummy IP address is updated in the config.xml file on all the nodes of the same Identity Server cluster.
Log in to the Identity Server terminals of the same cluster and check if the /etc/aaplugin/config.xml file has changed the IP address to the dummy IP address.
Delete the /etc/aaplugin/config.xml files from all the nodes of Identity Server cluster.
On the Access Manager Administration Console, click Devices > Identity Servers > Shared Settings > Advanced Authentication
Specify the original IP address of the Advanced Authentication Server in the Server Domain field and apply the change.
This updates the endpoints in the Advanced Authentication server.
Verify that the config.xml file is created successfully on all the nodes of the Identity Server cluster.
