By default, the Kerberos credentials for the Active Directory account you used to log on to the Windows computer are used for authentication on remote computers. If the remote computer is found and authentication is successful, you are not prompted to provide a password.
If you open a secure shell session using alternate Kerberos credentials or the Centrify PuTTY client cannot locate the target computer using the Kerberos credentials you provided, it will prompt you to provide the new credentials.
If you are prompted for a password, you can select Remember my password to have your password stored in the Windows credential cache the password so that you are not prompted for again the next time you access the same remote computer. By saving your password or your user name and password in the Windows credential cache, you can have single sign-on (SSO) access to remote UNIX and Linux computers using your Active Directory user credentials.
If the Centrify PuTTY client cannot find the computer you specify using your own or the alternate Kerberos credentials you have specified, you can try other credentials or other configuration options, such as Find machine from trusted domains. If the new credentials or configuration options are successful, you can then select Remember my password to access that computer the next time you open a connection to it. After saving your information, you can use single sign-on to access computers in external or untrusted forests or in disjointed domains.
You can manage cached passwords by using the Credential Manager Control Panel or by opening a Command Prompt window and typing
The number of times you can type the wrong password before Kerberos authentication fails and other authentication options are used can be configured by group policy settings.
