the supported mechanisms

worked

public static void worked(Oid mechanism)

Report that this mechanism was used successfully.

Parameters:

mechanism - that worked

Mark the mechanisms as failed.

Parameters:

mechanism - to mark

resolve

Parameters:

remote - to resolve

Returns:

the resolved InetAddress, or null if unresolved.

getCanonicalName

public static String getCanonicalName(InetSocketAddress remote)

Determines a canonical host name for use use with GSS-API.

Parameters:

remote - to get the host name from

Returns:

the canonical host name, if it can be determined, otherwise the unprocessed host name.

createContext

public static GSSContext createContext(Oid mechanism,
 String fqdn)

Creates a GSSContext for the given mechanism to authenticate with the host given by fqdn.

Parameters:

mechanism - Oid of the mechanism to use

Returns:

the context, if the mechanism is available and the context could be created, or null otherwise

closeContextSilently
