can the client token be reused ?

[karman-docker]

I am using this package to authenticate my application (on Windows) against a proxy server which requires Kerberos authentication. I am using negotiate.AcquireCurrentUserCredentials() and negotiate.NewClientContext() to get the client token which gets passed to the proxy server in Proxy-Authorization header.

Can this client token be reused for subsequent calls to the proxy ? Appreciate if you have any suggestions on any golang package to achieve this for maOS using GSSAPI.
