 *    pwd      {IN}     Password.
 *    wallet   {IN/OUT} Initialized wallet structure.

 *

 *    -----------       ----------------------
 *    File              Pathname (e.g. "file:/home/asriniva")
 *    Oracle            Connect string (e.g. "oracle:scott/tiger@oss")
 *
 *    There are also defaults.  If the WRL is NZT_DEFAULT_WRL, then
 *    the platform specific WRL default is used.  If only the wallet
 *    type is specified, then the WRL type specific default is used
 *    (e.g. "oracle:")
 *
 *    There is an implication with Oracle that should be stated: An
 *    Oracle based wallet can be implemented in a user's private space
 *    or in world readable space.
 *
 *    When the wallet is opened, the password is verified by hashing
 *    it and comparing against the password hash stored with the
 *    wallet.  The list of personas (and their associated identities)
 *    is built and stored into the wallet structure.
 *
