/* Some remarks on thread safety ...
|
||
|
|
*
|
||
|
|
* The thread safety of this class depends largely upon the thread safety of
|
||
|
|
* the underlying GSSAPI and Kerberos libraries. This code just loads the
|
||
|
|
* system GSSAPI library, and whilst it avoids loading known bad libraries,
|
||
|
|
* it cannot determine the thread safety of the the code it loads.
|
||
|
|
*
|
||
|
|
* When used with a non-threadsafe library, it is not safe to simultaneously
|
||
|
|
* use multiple instantiations of this class.
|
||
|
|
*
|
||
|
|
* When used with a threadsafe Kerberos library, multiple instantiations of
|
||
|
|
* this class may happily co-exist. Methods may be sequentially called from
|
||
|
|
* multiple threads. The nature of the GSSAPI protocol is such that a correct
|
||
|
|
* implementation will never call methods in parallel, as the results of the
|
||
|
|
* last call are required as input to the next.
