This new constant is a tuple of the exception types used by the underlying GSSAPI/SSPI implementation.
A paramiko server is now able to handle a restart of the user authentication during the GSS-API token exchange. This may occur, if the client detects a local GSSAPI problem (e.g. a missing kerberos ticket) and continues with another authentication method. The added test case test_2_auth_trickledown still fails, because the paramiko client contains a bug too.
Paramiko now tries other authentication methods, if "gssapi-with-mic" authentication may fails for a local reason (i.e. no kerberos ticket). Befor this change, any exception from the GSSAPI/SSPI caused the transport to be closed.

AuthHandler: handle "gssapi-with-mic" errors
Paramiko now tries other authentication methods, if "gssapi-with-mic" authentication fails (i.e. no kerberos ticket). Before this change, any failure of GSSAPI token exchange caused the transport to be closed.
