2000-10-04  Chris Toshok  <toshok@helixcode.com>

	* providers/nntp/camel-nntp-auth.c (camel_nntp_auth_authenticate):
	borrow some code from the imap provider to query the user for
	their password, and pass the user/passwd to nntp.  be extra
	paranoid and zero out the password before freeing it.

	* providers/nntp/camel-nntp-store.c (camel_nntp_store_init): add
	ALLOW_USER/ALLOW_PASSWORD/ALLOW_AUTH to the url flags.
	(nntp_store_query_auth_types_generic): return our list of
	auth_types.
	(nntp_store_query_auth_types_connected): broken, return same as in
	query_auth_types_generic.
