When the network connection is slow or unstable, the client logon or unlock process can take several minutes. A solution to this is to enforce the cached logon. In this case the Client will connect to Advanced Authentication Server to validate the credentials in background after the cached logon. By default, the enforced cached logon is not used and the Client will always try to connect to Advanced Authentication Server to validate credentials.
Perform the following steps to allow users to use the enforced cached logon:
Open the configuration file \Library/Security/SecurityAgentPlugins/aucore_login.bundle/Contents/etc/aucore_login.conf. If the file does not exist, create a new file.
Specify forceCachedLogon: true (default value is false) in the aucore_login.conf file.
Save the configuration file.
Restart the system.
