Issue: After installing Mac OS X Client and rebooting the system, the Client prompts an error message Endpoint not found and a user is unable to log in.
Reason: An endpoint for the client exists in the server or in the configuration file of the client.
Workaround: Perform the following steps:
Remove the endpoint for the client on the server in the Endpoints section of the Administration portal (if the endpoint specific to client exists).
Boot in the Safe mode and remove the endpoint_id, endpoint_name, and endpoint_secret parameters from the configuration file /Library/Security/SecurityAgentPlugins/aucore_login.bundle/Contents/etc/aucore_login.conf.
Restart the operating system.
