	This structure is modeled after authinfo structure from Courier Authlib.

	Either sysusername or sysuserid may be NULL, but not both of them.
	They, and sysgroupid, specify the authenticated user's system
	userid and groupid.  homedir points to the authenticated user's
	home directory.  address and maildir, are obvious.

	After populating this tructure, the lookup function calls the
	callback function that's specified in its second argument.  The
	callback function receives a pointer to the authinfo structure.

	The callback function also receives a context pointer, which is
	the third argument to the lookup function.

	The lookup function should return a negative value if the userid
	does not exist, a positive value if there was a temporary error
	looking up the userid, or whatever is the return code from the
	callback function, if the user exists.
